A. Site Selection & Mounting Template:

The R93PAT1 can be configured to house batteries & equipment in several configurations. The two most common are as follows:

• Mounted on a concrete pad at grade (Greenfield application).

• Mounted on a reinforced surface within an existing structure (e.g. rooftop) Regardless of configuration, a reinforced mounting pad or I-beam supporting structure is required for the enclosure to prevent the cabinet from shifting or overturning. The pad may require steel rods to prevent cracking and to ensure that the anchor bolts will not be pulled out of the pad. A slab on grade is not sufficient because of the effect of frost heaving on the pad. The pad provides door clearance and a work area around the enclosure. If a larger work area is desired, a slab on grade can be poured around the mounting pad. The slab must be designed and installed in accordance with local building codes.

NOTE When designing a pad or supporting structure, be sure to account for the maximum weight of both cabinets. R93PAT1 cabinet (~1500 lbs. cabinet with AC Demark Cabinet, DC Plant, & 4x Battery Boxes) and all accessory items (power supplies, batteries, etc.) that will be installed (Typically up to 3500 lbs. with 400A, -48V DC Plant, 4x Battery Boxes, [16] 170Amp*Hr batteries). R93BTS1 cabinet (~1400 lbs. cabinet with fully loaded Siemens UMTS,) and all accessory items that will be installed. Design the footprint of the pad to accommodate the R93PAT1 and R93BTS1 Cabinets and personnel access (~2'-3' for door swing-out) as necessary.

The site should be chosen to avoid these potential situations as well:

• small alcoves that enclose the cabinet on 3 or 4 sides

• small alcoves that receive direct sun in the mid to late afternoon

• any surface within 4 feet (120 cm) of the rear of the cabinet

• hot air exhaust from neighboring buildings/structures

• hot surfaces such as dark asphalt, tarred roofs, crushed rock

• areas with architectural controls or environmental restrictions

• areas prone to flooding

The first five items may cause premature high-temperature shutdown. Small spaces or certain surfaces that receive direct sunlight tend to retain the solar energy resulting in a much hotter microclimate. Hot exhaust from neighboring structures or re-circulated heat exchanger exhaust due to a nearby surface can also result in an undesirable temperature rise above design targets. Heat gain within the cabinet has many dependencies such as site loading and traffic, solar thermal loading, geographical location, time of day, weather, cabinet orientation, surroundings, and external air movement. Plan the site to meet or exceed the requirements of any local architectural codes, bylaws, or environmental restrictions, if applicable. The cabinet should not be subject to flooding conditions, as the sealing design is not intended for complete or partial immersion in water, mud or debris.

WARNING PERSONAL INJURY HAZARD 1. Carefully factor in the combined weight of all materials to be lifted (cabinet, internal equipment, air conditioners, etc.) before engineering a lifting apparatus. A site installation engineer should be consulted to verify adequate support prior to lifting anything. 2. Furthermore, DO NOT lift the cabinet with batteries installed. The structure may bend from the excessive weight causing damage to the cabinet and/or the batteries resulting in a potentially hazardous material spill.



3. Carefully follow any installation directions from the manufacturers of installed equipment (radio gear, etc.), which may include populating the cabinet after it has been lifted on site. Failure to do so may result in equipment damage and lapse of warranty.

Figure 2 below shows the pad layout for mounting hardware for the R93PAT1/R93BTS1 Cabinet(s). The R93PAT1 cabinet can support up to (16) 170Ahr batteries for a combined weight of ~3500 lbs. The R93BTS1 cabinet can support up to ~1400 lbs. The bottom area of the two cabinets is ~14.85 ft

2 which

means that the pad (or supporting structure) must be designed to support ~330 lbs./ft2 minimum:

Figure 2 – R93PAT1/R93BTS1 Pad Layout.

1. Pad Install: For pad install, locate mounting anchors in the pad according to the layout in Figure 2. Section C covers specific instructions for accessing lifting eyes and mounting/securing the cabinet.



B. Unpacking and Preparing for Mounting:

WARNING Do not lift a cabinet with any optional batteries installed. Once the cabinet has been securely set in place, follow instructions for battery installation.

1. Remove packaging materials to expose the cabinets as mounted on the provided pallet for

shipping. 2. The cabinet(s) is (are) pre-mounted to a plinth, simply unbolt the plinth from the pallet and

retain the mounting hardware for future mounting to the pad/support structure. 3. The following table gives cabinet details so it can be determined if lifting apparatus is

required for mounting or if standard hand-trucks & dollies may be used: (Verify any transporting equipment is rated for the weights specified)

C. Accessing Lifting Eyes/Mounting the Cabinet (If necessary):

WARNING PERSONAL INJURY HAZARD 1. Carefully factor in the combined weight of all materials to be lifted (cabinet, internal equipment, air conditioners, etc.) before engineering a lifting apparatus. A site installation engineer should be consulted to verify adequate support prior to lifting anything. 2. Furthermore, DO NOT lift the cabinet with batteries installed. The structure may bend from the excessive weight causing damage to the cabinet and/or the batteries resulting in a potentially hazardous material spill. 3. Carefully follow any installation directions from the manufacturers of installed equipment (radio gear, etc.), which may include populating the cabinet after it has been lifted on site. Failure to do so may result in equipment damage and lapse of warranty.

1. To access the pre-installed lifting eyes to set the cabinet(s), remove the hardware securing

the Top Cap to each respective cabinet (front retaining screws) and lift it off (See Figure 1). 2. Secure lifting apparatus as necessary to the 4 lifting eyes. 3. If installing the cabinet on a concrete pad, it may be necessary to lay down a layer of ½"

thick neoprene gasket where the cabinet will be placed prior to setting it down to prevent potential corrosive effects. This can be supplied by Purcell Systems upon request.

4. If installing the cabinet on a steel supporting structure, verify the steel is adequately galvanized to prevent possible corrosion with the aluminum cabinet.

5. Once the cabinet (and/or optional plinth) is settled over the intended mounting bolts, secure using appropriate hardware (washers, nuts).



D. Grounding Service Connection:

1. The various "Equipment Grounds" of the cabinet (DC Plant 0V Buss, BTS grounds) are bonded to the cabinet's Master Ground Bar (MGB) that is accessed on the inside left side of the Equipment Compartment. The MGB is subsequently bonded to an Equipment Ground Bar (EGB) located inside the Telco Demark Cabinet. (See Figure 3 below)

2. All necessary grounds for future equipment to be installed in the Equipment Compartment should be bonded to the MGB (see Figure 3) via 2-hole lugs (5/8" centers, ¼"x20 stainless steel h/w).

3. The ground riser from the site "Single-Point Ground" (e.g. buried ring) should be connected to the EGB via CAD-weld to establish the "Equipment Ground." (See Figure 3)

4. For the "Telco Ground," another ground riser from the site "Single-Point Ground" should connect to the Telco Ground Bar (TGB) mounted inside the Telco cabinet via CAD-weld. (See Figure 3)

5. All other "dead-metal" (cabinet, rack rails, Telco Cabinet, etc.) are bonded to the cabinet frame itself. To tie the "Cabinet Ground" to the site "Single-Point Ground," attach a #2 solid riser with 2-hole lug (5/8" centers,1/4" dia.) to the external cabinet ground studs located below the front door. Treat the surface with No-ox prior to connection and use appropriate hardware.

6. Grounding of the optional plinth is up to the interpretation of the installation contractor according to customer grounding specifications.

NOTE Adherence to grounding specifications from equipment manufacturers and end-users is strongly recommended. Failure to do so may void warranties for that gear.

3. AC Power Hookup using Purcell Power Cabinet (PPC) Termination Module (TermMod):

For R93PAT1 cabinets using the PPC for AC power distribution, it is assumed that the site meter is mounted at a remote location and the incoming service is brought to the cabinet in either appropriately sized conduit (see Figure 4) or an overhead drop. Once the AC service is brought to the cabinet, it is designed to enter from beneath the PPC through either of 2 runs of 2" conduit near the rear of the cabinet. The field contractor must couple to the provided runs that will transport the AC Power Service through the Telco Compartment into the AC Power Compartment (See Figure 4):

3.1 Install adequately sized conduit & fittings from the previously installed utility service

stub-up area (refer to "Site Preparation Instructions") and connect to the provided 2" conduit stubs.

3.2 The internal connection points can be accessed by opening the PPC's swing-out dead-front.

3.3 The two "hot" conductors (Line1 & Line2) should be installed in the "Utility Main Breaker Input Lugs" on the top of the Commercial Main Breaker (see Figure 5. MTS unit shown).

3.4 The Neutral conductor (white) should be installed in the large lug position of the Neutral Buss located above the 30-position Load-Center.

3.5 The Ground conductor (green) should be installed in an available position on the Ground Buss located next to the Load-Center (see Figure 5). Per Code, the AC Service Ground should be bonded accordingly to a driven rod, etc. by the field contractor.

3.6 For PPC's with MTS's: Under normal circumstances, the "Manual Transfer Switch" (sliding bar) should have the open end over the left-most breaker allowing the Commercial Disconnect to be ON (see Figure 5).

3.7 The electrician should ensure all other breaker, ground & neutral connections are secure & tight before closing up the PPC dead-front & cover.

4. Initial Automatic Transfer Switch Set Up 4.1 The ATS requires some initial set up and programming before power up. 4.2 Refer to the ASCO manual for programming of the available ATS features. 4.3 The internal connection points can be accessed by opening the TermMod's swing-out

dead-front. 4.4 The ATS exercise timer has a back up battery (9 volt). This battery has a jumper that

needs to be changed in order to work (refer to Figure 7). 4.5 Move the battery jumper to the ON position. This will ensure that the timer program is

saved in the case of complete power failure. 4.6 The two "hot" conductors (Line1 & Line2) should be installed in the "Utility Main

Breaker Input Lugs" on the top of the Commercial Main Breaker (see Figure 5). 4.7 The Neutral conductor (white) should be installed in an empty lug of the Neutral Buss

located to the left of the ATS Switch (see Figure 6). 4.8 The Ground conductor (green) should be installed in an available position on the

Ground Buss located next to the Load-Center (see Figure 6). Per Code, the AC Service Ground should be bonded accordingly to a driven rod, etc. by the field contractor.

*The electrician should ensure all other breaker, ground & neutral connections are secure & tight before closing up the PPC dead-front & cover.

5. Generator Operation with MTS Option (refer to Figure 5 for procedures): During the loss of Commercial power, it may be necessary to switch over to generator power by hooking a generator up to the provided Generator Input on the right side of the PPC. This input is pre-wired to the Generator Main Breaker, Neutral & Ground busses.

5.1 Connect portable generator connector to the side input of the PPC. 5.2 Open the front door of the PPC to access the Manual Transfer Switch (it should be

positioned so that the blocking "tab" is over the Generator Main Disconnect (right side breaker).

5.3 To slide the Manual Transfer Switch to a position where the Generator Disconnect can be turned ON, you must first turn the Commercial Disconnect OFF (slide switch lever DOWN).

5.4 Move the blocking "tab" of the Manual Transfer Switch to the leftmost position. 5.5 Now the Generator Disconnect can be set to the ON position (slide switch lever UP).

This will allow the generator to feed power to the load-center below. 5.6 Once commercial power is restored, the Generator disconnect can be set to the OFF

position, the Manual Transfer Switch can be moved, and the Commercial disconnect turned back ON.

6. Generator Operation with ATS Option: During the loss of Commercial power, it may be necessary to switch over to generator power by hooking a generator up to the provided Generator Input on the left side of the TermMod. This input is pre-wired to the Generator Main Breaker, Neutral & Ground busses.

6.1 Connect generator connector to the side input of the TermMod. 6.2 Open the Top Door of the TermMod and Open the Dead Front Cover. 6.3 Connect the Generator Run Signal Wires to the ATS Switch (refer to ASCO Manual) 6.4 Ensure the Generator Main Breaker is in the ON position. 6.5 Leave both Main Breakers in the ON position to ensure that ATS will transfer to Utility

Power as soon as it is available. 6.6 Follow the instructions for the Grasslin Timer to set the Generator Exercise Timer. 6.7 Refer to the ASCO manual to set the exercise timer for full load test or no load test.

NOTE The ATS will not transfer back to utility power unless it can turn off the generator. The generator run signal wires must be connected to the ATS. Refer to the ASCO manual for more information



7. Additional Electrical Features: 7.1 Utility AC Receptacles:

There is a 4-receptacle gang-box on the inside left wall of the front of the RAC82PWACSMX4SD that is wired to a 20 Amp, 1-pole breaker in the PPC. Two of the four receptacles are GFI-protected and can be used by service personnel for misc. equipment.

7.2 Interior Light: On the front of the ceiling of the Power and Battery Bays, there are interior lights that can be turned on manually by pressing the rocker switch to ON. (If DC-powered lights & smoke alarms are used, verify the DC Breakers feeding those components are ON for operation).

7.3 Smoke Alarm: There is a smoke alarm installed on the front right corner of the Battery Bay ceiling. It has a manual test switch and reports a Normally Closed dry-contact alarm.

7.4 Installing & wiring additional load-breakers: QO compatible load-breakers (10kAIC rated) can be installed in the available positions of the Load-Center for future loads (e.g. BTS heater inputs) when the ISATS200 PPC is used. Ensure installation & wiring is performed by a licensed electrician according to NEC and any other related codes.

NOTE Ensure the power & grounding systems are engineered to meet the specific application as well as local & national electrical codes.

F. Communications Service Connection (Optional):

1. Telco demarcation and provided T-span surge suppression equipment can be mounted inside the optional Telco Demark Cabinet on provided plywood.

2. Bring in service through any of the bottom conduit knock-outs in the Telco Demark Cabinet. 3. Ensure approved conduit fittings are used to maintain a weather-tight seal. 4. Connect incoming Telco lines from previously stubbed-up conduit to the dedicated

demarcation equipment (e.g. channel bank, etc.) according to equipment instructions & specifications.

5. There is a small dedicated ground buss inside the Telco Demark Cabinet for grounding installed equipment and any surge suppression (Refer to the provided installation manual for the optional Surge Suppressors for details on mounting, grounding, and maintenance).

NOTE Strict adherence to installation & grounding specifications from equipment manufacturers is strongly recommended. Failure to do so may void warranties.



G. Battery Installation:

CAUTION Installation or maintenance of batteries should be done by qualified personnel because of potential exposure to harmful DC voltages and chemicals if batteries are misconnected or damaged. The batteries should always be disconnected (Quick-Connects or breakers) when working on them. In addition, careful attention should be given for proper battery polarity connection. Failure to connect batteries correctly could result in injury to personnel from arcing and damage to the DC rectifiers and any connected equipment that may void its warranty. Batteries are very heavy so extreme caution should be exercised when handling.

The R93PAT1 can have up to 4 battery boxes located at the bottom of the Equipment Compartment (See Figure 1) that can accommodate up to 150-170 Amp*hr strings per tray (shipped separately) of Valve-Regulated Lead Acid (VRLA) batteries (1 string = 4x12V batteries configured with intercell connectors for 48V systems). Further, battery cables & optional temperature compensation sensors are pre-connected to the DC Power Plant making hook-up fast and easy. Hydrogen vent tubing is also in place (with per string attachment kits) for rare occurrences of battery "out-gassing."

1. Open the door of the Equipment Compartment after the cabinet has been securely mounted in place.

2. Make sure the batteries are disconnected (via rear Quick-Connects or Battery Breakers).

3. At initial installation, any optional rectifiers (packaged in boxes) located in the battery trays need to be removed and stored in a safe location before populating them in the DC Power Plant (covered in Section G of this manual).

4. Battery String1 should be installed in the bottom tray, String2 (optional) above String1, etc. 5. Move the battery cables/temp sensors out of the way during battery install. The batteries

should be placed so there is ~ ½" gap between them (there should be 4 to a row). 6. The battery connection cables come pre-crimped with a 1-hole lug to connect to the Batt1(-)

and Batt4(+) terminals for each string (See Figure 8). For safety, they have insulating heat-shrink over the metal lugs. For each string of batteries to be installed ONLY, strip off the insulation covering the metallic lug on the battery cables.

7. Once the lugs are exposed, connect the cable labeled "Str1 +" to the Batt4(+) terminal. 8. Next, connect the cable labeled "Str1 -" & the Battery Temperature Compensation probe

(with ring terminal) to the Batt1(-) terminal. (See Figure 8) Connect battery cables to batteries (Batt1[-] & Batt4[+] for String 1) before any intercell connectors are installed 9. Connect the intercell connectors as seen in Figure 8 (Batt1[+] to Batt2[-], Batt2[+] to

Batt3[-], Batt3[+] to Batt4[-]). NOTE: When the last intercell connector is attached, there may be a slight spark. This is normal operation.

10. Refer to the Battery Manufacturer's documentation on how to hook up the hydrogen vent tubing (see Figure 8). Each shelf of batteries should be strung together and then attached to the pre-installed manifold.

11. If a 2nd or 3rd string of batteries is to be installed, follow steps 8-10 above for "String2" and/ or "String3."

12. When all batteries are installed, complete the circuit to the DC Plant (plug in Quick-Connects or turn Battery Breakers ON).

NOTE If the batteries do not have outgassing "ports", disconnect the tubing from the top & bottom outgassing valves located on the right side of the front door to allow the cabinet to passively vent. See Figure 9.

H. DC Power Plant Setup & Operations:

The DC Plant has been pre-configured and wired to power one Siemens NB-580 cabinet via 2x 125 Amp breakers. DC powering cables are pre-installed so verify these breakers and the Battery Disconnect Means are in the OFF position before making any connections to the BTS's. It is recommended that the DC Power Plant go through initial start-up testing before connecting DC Power Cables. Several other DC breakers are pre-configured to feed various systems (Emergency Vent System [EVS], DC lights, etc.). Additional ones can be installed.



The "Installation & Operations Manual" for the dedicated DC Power Plant comes with every R93PAT1 cabinet in the document holder. It is strongly recommended to refer to that manual for specific instructions regarding operation and programming of the plant.

1. Connecting Future DC Loads (Performed by Qualified Technician ONLY):

1.1 Future DC loads can be installed in the user-defined 23" rack area and wired from any available breaker positions.

1.2 Follow the appropriate section in the DC Plant Installation Manual for putting load breakers into any of the available positions and wiring to the loads.

1.3 Cables should be routed over the top sides of the DC plant and come down

I. Installing the Siemens NB-581 into the R93BTS1 Cabinet:

The mounting pattern for the R93PAT1 & R93BTS1 Cabinets (into which the Siemens NB-580 UMTS rack is installed) are shown in Figure 2:

With the R93BTS1 Cabinet, and its internal BTS mounting plinth (see top “Before BTS Install” photo in Figure 10 below), securely tightened down with flat-washers, lock-washers & nuts to the pad, the following steps should be followed to install the UMTS NB-580 onto the internal mounting plinth (platform):

1. Open the front door of the R93BTS1 and remove the bottom wind-prop hardware to allow

for full door swing out. Retain all parts for re-installation. 2. The internal mounting plinth is pre-installed with the Siemens Zone4 BTS Feet Retaining

Brackets that are used to secure the feet of the R93BTS1 Bay (see Figure 10 below). At initial installation, remove the hardware securing the Retaining Brackets and set aside for future install.

3. Carefully maneuver the Siemens BTS through the front door of the R93BTS1 and position it onto the internal plinth so that the brackets can retain the feet.

4. Using the methods called out in the Siemens Installation Instructions, adjust the leveling feet of the BTS until it is balanced on the plinth.

5. For the front & rear feet, re-position the BTS Feet Retaining Brackets so that they secure the BTS in place on the plinth. Securely tighten down the bolts& washers holding the Retaining Brackets to the Plinth. (See “After BTS Install” photo at the bottom of Figure 11)

Alternate Mounting Option: The photo to the right in Figure 9 shows an alternative Zone4-compliant mounting structure. Instead of bolting the Siemens Zone4 Brackets to the internal plinth, a set of slotted steel “skis” with securing brackets can be installed in the R93BTS1. The BTS is positioned in a similar manner from the front of the cabinet except its feet are captive inside the “guide slots” until it reaches the back of the skis. At that point, the front retaining brackets are bolted in place securing the R93BTS1 Bay in place.

6. The top rear panel of the BTS should be secured to the pre-installed Support Brace located

at the rear of the cabinet. Figure 11 shows this procedure.

Figure 13 below shows the mechanical & electrical connections that need to be made between the Power Cabinet and the UMTS BTS Cabinet:

Figure 13 – Power and BTS Cabinet Connection Points

Refer to Notations (1 through 7) in Figure 12 for the Following Connections:

1. Connecting Top Cable Raceways: 1.1 With the BTS Cabinet mounted adjacent to the Power or AuxBatt Cabinet per the

layout depicted in Figure 9, first remove the Top Caps and side Cable Raceway cover plates for the cabinets to be connected. Then, secure the Cable Raceway Ports together between the 2 cabinets by using the provided 8 sets of ¼”-20 bolts, washers & nuts.

NOTE: This procedure can be done for additional cabinets (Battery, MCPA, additional BTS’s, etc.) in the future if the site is expanded.

2. Routing 16-Pair Alarm Cable: 2.1 A 16-Pair Alarm Cable should be routed from the Main Alarm Block in the R93PAT1

through the cable port and enter the BTS Cabinet via one of the small waterproof grommets on the left rear side of the R93BTS1. It should then route to the “Mounting Plate for relocated Ext Alarms” (item 50, Figure 1) and connect to the corresponding External Alarm input terminals of the Siemens BTS. Each alarm (0 through 15) has a labeled Signal and Return wire. (Refer to Siemens documentation for details)

NOTE: This procedure is done only to the first cabinet.

WARNING If moving or accessing the BTS power cables, verify that the corresponding DC breaker and battery disconnect on the DC Power Plant in the Equipment Compartment of the R93PAT1 is in the OFF position. Failure to do so may result in personnel injury or damage to equipment. Work should be done only by a qualified technician.

3. Routing DC Power Cables to Feed BTS:

3.1 Route the DC Power Cables through the left-most 4” dia. port in the top of the BTS cabinet and connect the (+) and (-) power terminals, as well as the cable Ground per Siemens’ Installation Instructions.

WARNING Verify the AC breaker in the PPC feeding the R93BTS1 air conditioner is in the OFF position before doing any electrical work. Only qualified technicians should perform this work.

4. Route 230VAC Power Cable & Install 30A Feed Breaker for Air Conditioner:

4.1 The air conditioner in the BTS Cabinet has been pre-wired with a length of power cord spooled up in the top compartment to route to an appropriate breaker in the PPC of the Power Cabinet. Route the 3x#10 AWG Power Cord (Figure 12) over to an available cable access port/grommet and feed it down and into the PPC. Remove the provided 30A, 2-pole breaker from the BTS cabinet and install it into an available position in the PPC Load-Center (in the OFF position) after opening its front door & removing the interior dead-front. Connect the power cord to the breaker just installed.

5. Route DC Power Cable for Emergency Vent System: 5.1 The High-Heat Emergency Vent System (EVS, See Section M for details) in the BTS

Cabinet requires a 15A (48VDC) feed from a breaker in the DC Plant PDU. Purcell Systems has provided a spooled-up length of cable (with crimp-on ring terminals) to route from the BTS Cabinet to the Power Cabinet and feed into the DC Plant. Figure 12 shows the path for this cable as it is inserted through an available small gray grommet above the DC Plant. Once inside the Equipment Compartment of the Power Cabinet, route enough wire length to reach the DC connection terminals for a pre-installed 10A breaker, cut the extra length, then strip back ~3-4” of the outer jacket of the 2x#14AWG cable to reveal the white & black wires. Strip the wires and crimp on the provided ring-terminals. The white wire should connect to the Zero Voltage buss in the DC Plant (top) as it is the (+) terminal. The black wire should connect to the –48V buss plate above a 15A breaker (bottom) as it is the (-) terminal.

6. Route BTS Alarm Cable to “Grouped” Alarm Block: 6.1 Each BTS Cabinet is capable of reporting 3 Normally Closed dry-contact alarms

(Door Open, Hi-Heat System ON, and Air Conditioner Malfunction). These 3 alarms are grouped into an Alarm Transport Cable which is spooled-up in the top of the BTS Cabinet (Figure 12). The Alarm Scheme for the entire configuration (1 Power Cabinet, an optional Aux Batt Cabinet, and various BTS Cabinets) is set up so that if any cabinet has a specific alarm, it will be reported as a “grouped” alarm (e.g. a Door Alarm on BTS3 will show up as a generic “Door Alarm” to the Siemens Alarm Monitoring System). In order to “group” these alarms for the Power and BTS Cabinets, an optional “Grouped” Cabinet Alarm Block can be installed on the rack rail of the Equipment Compartment in the Power Cabinet (Figure 1) and used to put these Normally Closed alarms in series (if an alarm occurs, it creates an Open in the circuit). The BTS Alarm Transport Cable should be routed over to an available cable access port/grommet and fed down through to the “Grouped” Alarm Block. Strip back ~12” of the outer insulation to expose the signal wires. Figure 14 below shows how to hook-up alarms from each BTS (or ABC Cabinet) to the correct position:



Figure 14 – “Grouped” Cabinet Alarm Block COnnections

As can be seen on the right in Figure 14, each cabinet has alarm inputs for a Door Alarm, Hi-Heat System Alarm, and Air Conditioner Alarm. The 2-position red jumpers on the left are used to put these inputs in “series” while the red jumpers on the right are used as place-holders for BTS & ABC inputs until they are installed. When the BTS alarm cable is connected, remove the rightmost 2-position red jumper placeholder with a small flat-head screwdriver and connect the appropriate pair (e.g. BTS1 Alarms should route to the inputs labeled: “Door BTS1”, “HH BTS1”, and “A/C BTS1”).

7. Routing Optional T1 Connection Cables: 7.1 There may be some optional 16-pair and 6-pair T1 connection cables to route back to

the Telco Demark Cabinet of the R93PAT1. These can be routed through any available cable grommet in the Power Cabinet and then eventually into the Telco Demark area for termination through an available K.O.

K. RF Services Connection (Optional):

The 4” diameter “cable ports” situated on the left side of the R93PAT1 (See Figure 1) can be used to route RF coaxial cables and other data lines.

1. Configure the RF lines from the BTS’s to pass through the “Intercabinet Cable Pass-through

Port” (Figure 1) and route through the Top Compartment and out the appropriate 4” dia. RF port in the left side of the R93PAT1 (Figure 1).

NOTE It is the responsibility of the site installer to provision strain-relief & cable-supporting structures (ice bridges, etc.) before attaching the RF cables to the R93PAT1 Cabinet.

2. Mount any optional coaxial interface connectors (in-line surge suppressors, etc.) or feed-through hardware in the RF port. Ensure all installation and grounding practices are followed according to manufacturers’ instructions. Failure to do so may compromise performance or void warranties.

L. Alarm Issues:

There is an optional “Alarm Collection Block” that can be located on the right front side of the R93PAT1 Cabinet. Normally Closed dry-contact alarms related to the DC Plant (Rect Fail, AC Pwr Fail, etc.) and on-board cabinet accessories (Emergency Vent System [EVS], TVSS & Door alarms) are collected here. The 16-Pair Alarm Transport Cable outputs are tied to the corresponding inputs (DC Plant, EVS, TVSS & Door alarms) via the Main Alarm Block mounted on the right front side in the cabinet.

1. Field Wiring User-Defined Alarm

CAUTION When working on alarm terminals located inside the Power Cabinet, there are harmful voltages present so extreme caution should be exercised and work should be done only by a qualified technician.

1.2 The incoming alarm should be an Open or Closed Relay state and have 2 lead wires

(a Signal and a Return). 1.3 Place a narrow flathead screwdriver (tip<1/8”wide) in the orange slot next to the input

terminal on the left-side of the alarm block to be connected. See Figure 15. 1.4 Insert the Signal wire into the adjacent input hole and lever the screwdriver towards

the center of the block until it “locks” the wire in place. Tug on the wire slightly to verify a solid connection.

1.5 Repeat steps 2 & 3 above for the Return wire for the corresponding alarm position (directly below the active Signal wire). Refer to the labeling on the block.

M. Air Conditioner Considerations:

An air conditioner is mounted on the rear door of the Equipment Compartment in the R93PAT1 and R93BTS1 cabinets to regulate internal cabinet temperatures. The thermostat to control the A/C turn-on point is accessible by removing the outer cover & screen filter on the unit. The air conditioners also have internal heaters for use during colder months designed to turn on at 40°F. This turn-on point is not adjustable. Each cabinet has the corresponding “Installation & Operations Manual” for the attached air conditioner included in the documentation holder. Please refer to that manual for specific information related to that product. Retain that manual for any future maintenance. Ensure that the corresponding AC Breakers for the respective air conditioners are turned ON for operation.



N. Hi-Heat Emergency Vent System (EVS) Details:

Figures 16 and 17 below show the components of the Hi-Heat Emergency Vent System (EVS) for the R93PAT1 and R93BTS1, respectively. Both the upper exhaust (fan evacuated) and lower intake ports feature dampers to maintain the environmental integrity of the cabinet when the internal cabinet temperature is below the turn-on threshold controlled by the BLUE thermostat knob. Once that threshold is exceeded (indicating an emergency situation like AC Power or Air Conditioner Failure, the system draws DC power from the batteries to open the dampers and run the fans to cool with ambient air. The RED thermostat knob controls the setpoint at which a Normally Closed dry-contact alarm (Open on alarm) is asserted for remote monitoring of a high-heat situation.

1. To Test Fan & Damper Operation:

1.1 Verify the DC Breaker feeding the EVS to test is in the ON position and that either 24V or 48V power is available (based on DC Plant voltage) either through rectifier or battery power.

NOTE The EVS is either +24V or +48V powered. Verify correct polarity so that the + DC power terminal connects to the RED feed wire.

1.2 Using a small flat-head screwdriver, rotate the BLUE knob counter-clockwise until the

set point is below the ambient temperature. 1.3 You should hear the relay click engaging the DC fans and causing the motors to open

the intake & exhaust dampers. 1.4 Once system operation is verified, rotate the BLUE knob clockwise until the system

shuts off and adjust the set point back to the factory default of 110°F.

2. To Test the Alarm Transport: 2.1 Using a small flat-head screwdriver, rotate the RED knob counter-clockwise until the

setpoint is below the ambient temperature. 2.2 The alarm contacts at the thermostat & the main alarm terminal block of the Power

Cabinet should change from a "Closed" state to an "Open" state. 2.3 Once system operation is verified, rotate the RED knob clockwise to the factory

default of 110°F. You should see the alarm state change back to "Closed."
