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:
S The UPS has an overtemperature condition.
S The UPS has an overload condition of 103 to 112% for 2 minutes.
S The UPS has an overload condition of 112 to 150% for up to
30 seconds.
S The UPS detects a fault in the UPS electronics.
S The UPS has been transferred to Bypass mode through the front
panel (see page 31).
NOTE If the UPS electronics fail, the UPS provides surge-protected utility power; frequency
conversion (FC) UPS models no longer convert the utility frequency to the load.
Standby Mode
When the UPS is turned off and remains plugged into a power outlet,
the UPS is in Standby mode. The
μ
indicator flashes and the bar graph
indicators are off, indicating that power is not available to your
equipment. The battery recharges when necessary.
NOTE For 208–240V models, the output receptacles may remain electrically live (up to
110–120V). Unplug the UPS to ensure power is not available to the output receptacles.
