Manual Bypass Operation (for power module maintenance or replacement) (continued)

UPS Power/Battery Module Removal

STEP 1. Disable PowerAlert Software and disconnect communication cables from the

communication ports

on the UPS power/battery module.

STEP 2. Press UPS's “OFF” Button

, if the UPS is powered, until you hear a beep and see a

“BYPASS MODE” message shown in the LCD Display

STEP 3. Turn the detachable PDU's Bypass Switch

to “BYPASS”.

STEP 4. 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 5: Remove the four screws that hold the detachable PDU to the power/battery module.

STEP 6: 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. If the sections are detached in a rackmount

application, ensure that each section remains adequately supported by the UPS’s

rackmount rails. Remove the rackmounting hardware from the front panel of the UPS;

slide the power and battery modules forward, and remove. If it is desired to leave the

detached PDU in the rack, hang the unit in the back of the rack on the installed PDU

hangers by the screws used to attach the PDU to the UPS system. (Refer back to page

3 for PDU hanger bracket installation).

If the sections are detached in a tower application, ensure that the PDU is supported

by the UPS’s tower feet. Adjust the tower feet so they are as close together as possible.

WARNING! High Voltage! Risk of electrical shock! SEE BELOW.

STEP 7: Loosen the screws

in the contact cover

. Slide the cover over the contacts

Tighten the screw

to secure the cover. Warning: Use extreme caution when

handling the PDU. Do not allow the contacts to touch any surface.

To reattach the PDU, reverse the process listed above.
