4. Turn on all connected equipment (loads). To use the UPS as a master ON/OFF switch, be sure all

TURNING ON THE UPS
Make sure the battery is connected before turning on the UPS! Then, press the button on the
front panel to power up your UPS. This will power up connected equipment. (Make sure connected
loads are switched to their ON position).
The UPS charges its battery when it is connected to utility power. The battery charges
fully during the first four hours of normal operation. Do not expect full run time during
this initial charge period.
The unit performs a self-test automatically when turned on and every two weeks thereafter (by de-
fault). Refer to details below on changing the default interval.
120V Models: Check the site wiring fault indicator (located on the rear panel, see Rear Panel, be-
low). It lights up if the UPS is plugged into an improperly wired AC power o utlet. Wiring faults de-
tected include missing ground, hot-neutral polarity reversal, and overloaded neutral circuit.
If the UPS indicates a site wiring fault, get a qualified electrician to correct the
building wiring.
