5.1 Switching On the UPS

procedure is complete and the loads are supplied by the UPS..

To cold start the UPS, press and hold the on button on the front panel for approximately 3 seconds until the
LCD illuminates and the buzzer sounds, then release the on button. The UPS starts and the battery backup
LED (amber) illuminates. The cold start-up procedure is complete and the loads are supplied by the UPS.
4.
The UPS runs in backup mode and the buzzer sounds every 2 seconds if there is a power outage or an
over/under voltage. When utility power is restored, the UPS runs in utility mode and the buzzer is silenced.
5.2 Switching Off the UPS
1.
Press and hold the off button for at least 3 seconds to switch off the UPS. If you press the off button less
than 3 seconds, the UPS does not execute the shutdown command.
2.
In some cases, the UPS will switch itself off because of an overload, an output short-circuit, or a battery
cutoff point reached in the backup mode.
3.
The UPS automatically switches off the output, beeps for 5 seconds, then completely switches off.
5.3 Plug-in Charge
1.
If the input power cord is properly connected to the wall receptacle and the utility power is normal, the
UPS automatically starts charging the batteries without processing the switch on procedure.
2.
If the UPS isn't used for extended periods, charge the batteries for at least 8 hours every 3 months to
prevent the batteries from becoming discharged. The batteries will slowly discharge when left idle.
5.4 Auto-Restart
If the input power cord is properly connected to the wall receptacle and the utility power returns to normal, the UPS
automatically restarts and provides power to the output from utility.
5.5 Alarm Silence
1.
The alarm can be switched off by pressing the on button for approximately 1 second when in backup mode.

Unless other warnings or faults appear, the alarm remains silent after the alarm silence has been switched
off.
