The battery will charge to full capacity during the first few hours of normal operation. Do not expect full ‘on battery’ capability during this initial charge period.

2.After the UPS has ended the immediate self-test with online LED illumination, check the front display for any fault indicators (see Troubleshooting).

3.120 V models: Check the site wiring fault LED located on the rear panel. It will be illuminated if the UPS is plugged into an improperly wired utility power outlet (see Troubleshooting).

4.Turn on all connected equipment. To use the UPS as a master on/off switch, be sure all con- nected equipment is on.

Equipment is now powered and protected. Basic operation, user configuration, and software utiliza- tion can now be performed as required.

Battery Operation

The UPS switches to battery operation automatically if the utility power fails. While running on bat-

tery, an alarm beeps four times every 30 seconds. Press the button to silence this alarm.

If the utility power does not return, the UPS continues to supply power to the connected equipment until the battery is fully discharged.

Refer to www.apc.com for battery runtime charts.

When the UPS reaches the low battery shutdown warning (two minute default), the alarm will beep continuously until total shutdown. Connected equipment should be shut down during this time, unless being controlled by network monitoring software.
