APC 600 user manual Switch on load equipment, Switch on the UPS

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.
