Operation
Battery Mode
When the APS is operating during a power outage, the battery indicator illuminates. The front
panel displays the approximate percentage of battery capacity remaining (see figure 17). When
the utility power returns, the APS switches back to Normal mode operation and the batteries
recharge.
If battery capacity becomes low while in
battery mode, the battery indicator flashes
indicating approximately three minutes of
battery time remaining. When shutdown is
imminent, the self test (checkmark) indica-
tor flashes.
These warnings are approximate, and the
actual time to shutdown may vary. When
utility power is restored after an APS shut
down, the APS automatically restarts.
Bypass Mode
In the event of an extended APS overload or internal failure, the APS transfers your system to
utility power. Battery mode is not available, however the utility power continues to be passively
filtered by the APS. The bypass indicator illuminates when bypass mode is engaged. The APS
switches to Bypass mode when:
· The APS has an overtemperature condition.
· The APS has an overloaded condition of 101 to 110% for 2 minutes.
· The APS has an overloaded condition of 111 to 150% for 30 seconds.
· The APS detects a fault in the battery or APS electronics.
Standby Mode
When the APS is plugged in initially, or is turned off and remains plugged into a power outlet, the
APS is in Standby mode. The ~ indicator flashes and the bar graph indicators are not lit, indicat-
ing that the APS output receptacles are off.
