Cold Start

Load

When the UPS is off and there is no utility power, use the cold start feature to apply power to the connected equipment from the UPS’s battery. Cold start is

not a normal condition. To cold start the unit, push and hold the button. You will hear a short beep then a long beep. During the long beep, release the button and the unit will cold start.

The five-LED display on the left of the front panel shows the percentage of available power used by the connected equipment (load). For example, if three LEDs are lit, the connected load is drawing between 51% and 68% of the UPS capacity. If all five LEDs are lit, the connected load is drawing between 85% and 100% of capacity. Thoroughly test your entire system to make sure that the UPS will not become overloaded. In the graphic to the left, the load capacity threshold is listed next to the LED (these values are not listed on the UPS).

SELF-TEST

Manual

Self-

Test

The UPS performs a self-test automatically when turned on, and every two weeks thereafter (by default). Refer to the User Configurable Items table, be- low, for details on changing the default interval.

Automatic self-test eases maintenance requirements by eliminating the need for periodic manual self-tests. During the self-test, the UPS briefly operates the con- nected equipment on battery. If the UPS passes the self-test, it returns to online operation. If the UPS fails the self-test, the UPS lights the Replace Battery LED

and immediately returns to online operation. The connected equipment is not affected by a failed test. To confirm a self-test, failure, recharge the battery for 24 hours and perform another self-test. If it fails, the battery must be re- placed.

Press and hold the button until the UPS beeps twice to initiate the self-test.
