WARNINGLETHAL VOLTAGE POTENTIAL! Proceed with extreme caution. Before making any adjustments or connections to the circuit board, ensure that the unit is completely de-energized (see page 4)—input power must be disconnected and output power must be inactive.

WARNINGInstallation and service instructions are for use by qualified personnel only. To avoid injury, do not perform any servicing other than that contained in this instruction. Please read and understand this instruction before attempting to install or operate the Backup Power unit. All installation and service should be carried out in accordance with applicable standards and codes.

INSTALLATION & SETuPCAUTION

To prevent Electrostatic Discharge (ESD) damage, follow established ESD control procedures when touching the circuit board assembly.

Refertothephotoonpage5forcomponentidentification.1. MounttheBackupPowerUnitinthedesired

location—closeproximity to theactuator isnotnecessary.

2. Removethe10coverscrews(M8x1.25x30mm), thencarefullyremovethecover togainaccess to the circuit boardassembly.DO NOT FORCEFULLY REMOVE THECOVER–thismay cause damage to themating surfaces. If needed, use jackingscrews (recommendM8 x 1.25 x 40mm)in the appropriate holes (see the outlinedimensionsonthebackcoverforlocation)toevenlyseparatethecoverfromthehousing.

CAUTIONDamage sustained during setup and service (including cover removal and replacement) resulting from improper handling is not covered under warranty. Beck cannot be liable for any such damage which includes, but is not limited to, damage to the BPu cover-to-body interface which will affect the integrity of the seal protecting internal components.

3. Set S1 (control switch) to the 'on/charge'position (upward towards switch S2) fornormaloperation.

4. Complete the input, output and otherdesiredwiringconnectionsasshownintheappropriatewiring diagram beginning onpage6.Ifdesired,specificwiringdiagramsareavailableuponrequest.

5. Verifythattheunithasbeensettotheoutputfrequency specified in the order. LocateS2 (voltage frequency switch - see page5) on the circuit board. Use a flat-tippedscrewdrivertoturntheswitchtothedesiredoutput frequency. Turning the switchCWuntil it stops sets the frequency to 60Hz.Turning theswitchCCWuntil it stopssetsthefrequencyto50Hz.

6. Carefully replace the cover. DO NOTFORCEFULLYREPLACETHECOVER–thismaycausedamagetothematingsurfaces.Torquethecoverscrewsto18lb-ft(24N•m).

7. Energizeinputpower.

CAUTIONReinstall cover immediately after installation or service to prevent moisture or other foreign matter from entering the unit.

DE-ENERGIZING THE BPuWARNING

Review all prior WARNINGS and CAuTIONS in this instruction before proceeding.

1. Shutoffpowertotheunit.2. Removethe10coverscrews(M8x1.25x

30mm), thencarefullyremovethecover togainaccess to the circuit boardassembly.DO NOT FORCEFULLY REMOVE THECOVER–thismay cause damage to themating surfaces. If needed, use jackingscrews(recommendM8x1.25x40mm)inthe appropriate holes (see back cover) toevenlyseparatethecoverfromthehousing.

CAUTIONDamage sustained during setup and service (including cover removal and replacement) resulting from improper handling is not covered under warranty. Beck cannot be liable for any such damage which includes, but is not limited to, damage to the BPu cover-to-body interface which will affect the integrity of the seal protecting internal components.

WARNING

LETHAL VOLTAGE POTENTIAL! use extreme caution. The unit may still have stored power.

3. CarefullysetS1(controlswitch,seepage5)tothe'discharge'position(downwardtowardstheBecklogo)tobeginthedischargecycle.Thiswilldraintheultra-capacitorsofstoredenergy.Donottouchanyothercomponents!

SERVICE No routinemaintenance is required. Theonly customer-replaceable item on the BPUis thegasket between theunit and the cover.If the gasket sustains damage during coverremoval,itmaybereplacedwithBeckpartno.20-0661-90usingthefollowingprocedure:

WARNINGReview all prior WARNINGS and CAuTIONS in this instruction before proceeding.

Only use Beck silicone gasket part no. 20-0661-90. Failure to comply may result in component damage.

1. Ensure the environment is non-hazardousbeforeproceeding.

2. Shutoffpowertotheunit.3. If thecover is still on theunit, remove the

10coverscrews(M8x1.25x30mm),thencarefully remove the cover to gain accessto the gasket. DO NOT FORCEFULLYREMOVETHECOVER–thismay causedamagetothematingsurfaces. Ifneeded,usejackingscrews(recommendM8x1.25x40mm) in theappropriate holes (seebackcover)toevenlyseparatethecoverfromthehousing.

Beck cannot be liable for any such damage which includes, but is not limited to, damage to the BPu cover-to-body interface which will affect the integrity of the seal protecting internal components.

WARNING

LETHAL VOLTAGE POTENTIAL! use extreme caution. The unit may still have stored power. Do not come in contact with the circuit board assembly.

4. Completelyremovethegasketfromthecovermatingsurfaceof theBPU. Thegasket issiliconebasedwithaself-adheringstripandsetswithinthegroove.

BACKUP POWER UNIT CIRCUIT BOARD ASSEMBLY

S2 - VOLTAGE FREQuENCY SWITCH(Determines the frequency relevant to the output (50 or 60 Hz). Turning the switch CW selects 60 Hz, CCW selects 50 Hz. For safety, this switch should only be turned when the unit is completely de-energized).

S1 - CONTROL SWITCH(A two position switch. The 'on/charge' position (up) allows for normal operation; the 'discharge' position (shown) causes the ultra-capacitors to begin a discharge cycle—depending on the charge, it may take approx. 1 hour before the "PARTIAL CHARGE" light shuts off).
