Manual Bypass Operation (for UPS maintenance or replacement) continued

STEP 3. Part A: When the output is coming from the Primary UPS and the Secondary UPS needs repair, press the Secondary UPS system’s OFF button, if the UPS is powered, until you hear a beep and see a “STANDBY MODE” message shown in the LCD display.

Part B: When the output is coming from the Secondary UPS and the Primary UPS needs repair, press the UPS system’s OFF button, if the UPS is powered, until you hear a beep and see a “STANDBY MODE” message shown in the LCD display.

Part C: When both power modules show output is in Bypass, set the Maintenance Breaker Switch to the ON position before servicing.

STEP 4. Disconnect any external battery module(s) from the UPS power module being serviced.

STEP 5. At the rear of the UPS being serviced, remove the 2 screws that secure the PDU to the power module. If both power modules are in need of service, remove all 4 screws.

STEP 6. Remove the rackmounting hardware from the front panel of the UPS. Using an assistant at each end, carefully pull the power module away from the PDU, being careful not to disconnect the parallel cable. Once the power module is pulled from the PDU and powers down, disconnect the parallel cable from the power module.

The UPS power/battery module is now safely powered down and it can be detached from the PDU to perform maintenance/ replacement.

During this process, ensure that each section is properly supported after they are separated. If the sections are detached in a rackmount application, be sure that each section remains adequately supported by the UPS system’s rackmount rails. If the sections are detached in a tower application, be sure that the PDU is supported by the UPS system’s tower feet. Adjust the tower feet so they are as close together as possible.

WARNING! High Voltage! Risk of electrical shock!

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.
