Disable PowerAlert Software and disconnect communication cables from the communication ports A on the UPS power/battery module. STEP 2. Press UPS's "OFF" Button C , 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 B to "BYPASS". STEP 4. If an external battery module is connected to the UPS E , disconnect it from the UPS.

A E Step 1, 3, 4 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. D Step 2 WARNING! High Voltage! Risk of electrical shock! SEE BELOW. See Warning Statements below!
