utility power continues to be passively filtered by the UPS. The
indicator illuminates. The UPS transfers to Bypass mode when:
S The UPS has an overtemperature condition.
S The UPS has an overload condition of 101 to 150% for 30 seconds.
S The UPS detects a fault in the battery or UPS electronics.
Standby Mode
When the UPS is turned off and remains connected to utility power, 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 220–240V 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.
