Manual Bypass Operation (for UPS maintenance or replacement)

WARNING! For qualified service personnel only. Failure to follow the bypass procedure completely will not adequately power down

the UPS power/battery module, resulting in the continued risk of death or injury from potential contact with high voltage. The UPS's

power/battery module and detachable PDU are extremely heavy. This procedure requires several people to perform.

TheUPSsystemincludesaself-containedpower/batterymodulealongwithanindependent,detachablePDUwithabypassswitch.Thisswitch

allowsqualifiedservicepersonneltoremovethedetachablePDUfromthepower/batterymoduleforroutinemaintenancewithoutdisrupting

powertoconnectedloads.Whilethis switchissetto “BYPASS”,connectedequipment willreceiveunfilteredACmains power,butthe

equipmentwillnotreceivebatterypowerintheeventofablackout.

STEP 5. IfanexternalbatterymoduleisconnectedtotheUPS

,disconnectitfromtheUPS.

The UPS power/battery module is now safely powered down and it can be detached from the PDU

to perform maintenance/replacement.

STEP 6: RemovethefivescrewsthatholdthedetachablePDUtothepower/batterymodule.

STEP 7: Usingseveralassistantsateachend,carefullypullthedetachablePDUawayfromthepower/batterymodule.Duringthisprocess,

 ensurethateachsectionisproperlysupportedaftertheyareseparated.
