Bypass Mode
In the event of a UPS overload or internal failure, the UPS transfers your
equipment to utility power. Battery mode is not available; however, the
utility power continues to be passively filtered by the UPS. The
indicator illuminates. The UPS switches to Bypass mode when:
:
The UPS has an overtemperature condition.
:
The UPS has an overload condition of 101 to 150% for 30 seconds.
:
The UPS detects a fault in the battery or UPS electronics.
Standby Mode
When the UPS is turned off and remains plugged into a power outlet,
the UPS is in Standby mode. The
indicator flashes and the bar graph
indicators are off, indicating that power is not available from the UPS
output receptacles. The battery recharges when necessary.
Sleep Mode
If the UPS is on battery for approximately five minutes and supporting a
small electrical load (
10%), the UPS shuts down the load. This feature
conserves battery power. To enable this feature, contact your service
representative.
