4.0 Installation
4.6 Switch on load equipment
If you leave the load equipment switched on, you can use the UPS’s power
on button as a master system on/off switch.
4.7 Switch on the UPS
The UPS and your loads become energized when
you press and hold the power on button for a
second. At power-up, the UPS initiates a battery
self-test. During the test, the UPS briefly operates
the load from battery power. This test function
ensures that the UPS is working properly and that
its battery does not require replacement. If the battery is too weak to
support the load during the test, the UPS immediately returns to on-line
operation (the load is not affected). When the On Line indicator stops
blinking, the test is done.
Note: If the red Overload indicator lights, the UPS is overloaded. Unplug
equipment that does not require backing up, such as a printer, and restart
the UPS. If the Replace Battery indicator lights, recharge the UPS over-
night and retest.
Note: Refer to Section 7.0 for troubleshooting information.
