Method 2:
1) If the UPS indicates a bypass abnormal error code, you cannot remove the UPS without interruption and must first power down the
load and the UPS system.
2) Make sure the bypass setting is enabled in each UPS, then turn off the running system. All UPS systems will transfer to Bypass mode.
Remove all the maintenance bypass covers and set the maintenance switches from “UPS” to “BPS”. Turn off all input breakers and
battery breakers in the parallel system.
3) Turn off the output breaker and remove the parallel cable and share current cable of the UPS to be removed, then remove the unit
from the parallel system.
4) Turn on the input breaker of the remaining UPS system(s). The system(s) will transfer to Bypass mode. Set the maintenance switches
from “BPS” to “UPS” and reattach the maintenance bypass covers.
5) Turn on the remaining UPS systems.
