Caution: the AC input power source must be present when energising for the first time.

Press the ON / OFF button 23 .

The buzzer beeps and all the LEDs go ON. The buzzer beeps twice, then:

-If AC input power is available, LED 21 goes ON, indicating operation in ON-LINE mode.

-If AC input power is not available and the UPS is configured for automatic restart mode, the buzzer beeps three times and LED 22 goes ON, signalling operation on battery power.

All connected equipment is energised.

If LEDs 21 or 22 do not go ON or if LEDs 12 to 14 flash, there is a fault (see section 4.1).

LEDs 12 to 15 provide three different indications:

1 - Remaining backup time in percent (during normal operation).

2 - Percent load drawn by the protected equipment, when button 16 is pressed.

3 - Operating faults (flashing LED and beeps):

Ê12 Overload.

Ê13 UPS fault.

Ê14 Battery fault.

Status LEDs 18 and 19 for programmable outlets 1 and 2:

-LEDs OFF: the outlets are not supplied with power.

-LEDs flashing: status change in progress.

-LEDs ON: the outlets are supplied with power.

Outlets 1 and 2 can be remotely programmed and controlled. They may be used for sequential start-up of the protected applications, shedding of non-priority applications during operation on battery power, and priority management at the end of battery backup time to reserve the longest possible backup time for the most sensitive applications. These outlets are programmed using Solution Pac software.
