Front Panel Controls
(ON/STANDBY Button)
The ON/STANDBY button is a momentary switch that toggles between two
UPS Operating Modes (ON and STANDBY) when utility power is present.
Press the ON/STANDBY button and hold for 2 seconds until you hear a beep
to toggle back and forth between the two modes.
IMPORTANT:
When the UPS is connected to utility power, all receptacles will be
immediately energized regardless of the UPS Operating Mode selected by the UPS
ON/STANDBY button.
NOTE:
The ON/STANDBY button can also be used to turn the UPS OFF and place it in a
de-energized IDLE Mode. The UPS battery charger will be turned OFF. Power will be
turned OFF at all UPS receptacles, and all indicators will be turned OFF. Before the UPS
can be placed in the IDLE Mode, however, utility power must be absent and the UPS
must be either in the STANDBY Mode, BATTERY OPERATE Mode or an overload
condition must exist. To place the UPS in the IDLE Mode, press the ON/STANDBY button
and hold for 2 seconds until you hear a beep. The UPS will return to the ON Mode once
utility power is restored.
