9.3Starting the UPS in Bypass Mode
To start the UPS when the inverter output of the UPS is not available and the critical load needs to be energized:
1.Verify that the UPS circuit breakers are set as follows:
UPS Input Breaker (CB1) | OPEN |
|
|
UPS Battery Breaker or Battery Disconnect (CB2) | OPEN |
|
|
UPS Output Breaker (CB3) | OPEN |
|
|
UPS Bypass Breaker (CB4) | OPEN |
|
|
Backfeed Protection Breaker (FBP) | OPEN |
|
|
2.Close the UPS Bypass input feeder circuit breaker. Breakers CB4 and FBP close as soon as charged. If the breakers do not close, turn the Mode key switch to BYPASS for one second.
The critical load is immediately supplied by the bypass source, in Bypass mode, until the inverter turns on and the UPS transfers to Normal mode. The status indicator on the UPS control panel indicates the UPS is in Bypass mode.
3.The UPS system is now operating in Bypass mode. No backup is available.
