Refer to Figure 7 for the location of the modules within the 214246-006MD cabinet.

2.3.1 Power Supply Modules

2.3.1.1 Power Supply

The Power Supply Modules convert 90 to 260VAC 50-60Hz input voltages into 24VDC voltage supplying power to all controller modules.

Power is applied using the ON/OFF switches in the rear panel power input sections. AC input has a 2A fuse in line. To replace a fuse, remove the plastic cap in the rear panel AC module, replace the fuse and reinsert the plastic cap.

WARNING!!

Make sure the power is OFF before attempting to replace fuses.

2.3.2 Master Controller

The Master Controller communicates with the up link and down-link systems via RS-485 Serial Interface It provides all System telemetry to the user via front panel or RS-232 or RS-485 User Interface.

2.3.3 Front panel

The Front panel displays all System telemetry to the user via front panel LED and VFD graphic display. Refer to 3.2 for details.

3 Installation & Operation

Use the information in this section as a guide when making electrical connections to the 214246-006MD.

NOTE

Switch off main power to the unit before attempting to connect or disconnect interface cables. Failure to do so could damage the equipment involved.

3.1 Installation

The IDU controller is a standard 2 RU chassis, which can be mounted in an EIA-standard 19-inch equipment rack. If the controller is to be mounted in a rack, be sure to allow adequate clearance at the rear of the unit for attaching the cables.

NOTE

Recommended clearance above and below the unit is 3.5 inches. Allow a minimum clearance of 1.75 inches.

CAUTION!

Do not mount the unit using only the front panel mountings -the unit is too heavy. Failure to properly support the unit from front to back will deform the front panel and cause internal mechanical damage.

mitec Installation & Operation

Rev 0 Page 8

3.1.1 Environmental Conditions

Operate and store in a dry, well-ventilated area with a minimum of dust and vibration. Operating temperature range: 0°C to +50°C. Operating relative humidity range: 5% to 90%

Install the unit in an area protected form excessive dust and humidity. Failure to do so will result in malfunction or damage, and will reduce the service life of the unit.

CAUTION!!

Keep liquids away from the unit. Liquids penetrating to the interior of the unit will cause malfunction or equipment damage.

3.1.2 Safety

3.1.2.1 Electrical

Carelessness, or mishandling of the controller may damage the unit causing injury. Please adhere to the following:

WARNING!!

The unit is equipped with AC power cords and plugs. Do not tamper with, or attempt to reconfigure the cords or plugs supplied with the unit, as this can result in personal injury and void the warranty.

Always disconnect the power cords before attempting to:

• Unplug the connectors

• Replace parts

• Clean the unit

3.1.3 Electrical Connections

All electrical connections to the system are made on the unit's rear panel.

Once the controller has been installed, attach the cables from the WRK M&C and MRK M&C to the appropriate rear panel connectors on the controller. Refer to the detailed block diagram for connection details, and to the rear panel information in Figure 4 and Table 4.
