Manual Bypass Operation (for power module maintenance or replacement)
The following procedure only applies to UPS system configurations that include a 6kVA or 10kVA transformer module. The procedure details how to service or replace the power module while supplying equipment connected to the transformer module with utility power. NOTE: since the power module and battery module will be disconnected during the procedure, they will be unable to supply battery backup support to equipment connected to the transformer module in the event of a blackout.
WARNING! For qualified service personnel only. Failure to follow this procedure completely will not adequately power down the UPS power module, resulting in the continued risk of death or injury from potential contact with high voltage.
1.Disable PowerAlert Software and disconnect communication cable from the power module’s communication ports A .
2.Turn transformer module’s Bypass Switch B to “BYPASS”.
3.Press power module’s OFF Button C , if power module is powered, until a beep is heard and a “BYPASS MODE” message is displayed in the LCD panel D .
4.Turn off the transformer module's
5.Turn off the power module’s
6.Disconnect battery module cable from the power module’s battery connector H .
7.FOR 10kVA POWER MODULES ONLY: Use a voltage meter to check the cable connecting the power module’s terminal blocks I to the transformer module’s terminal blocks J to ensure the power module is no longer powered. Once it is no longer powered, remove the cabling.
The power module is now safely powered down and maintenance/replacement can be performed.
