5. Operation of the UPS
5.1 Start the UPS
After successful installation you have to push the mains switch backsides the UPS onto
„ON“. After that you press the ON/OFF push button at the front side of the UPS for the
duration of 2 seconds. Now the UPS starts and carries out a self-test.
5.2 Switch-off the UPS
Press the push button ON/OFF at the frontside and keep it pressed until the LED „Mains
OK“ (line normally) or the LED „Battery operation“(back up) goes out. If you don’t need the
UPS for a duration longer than one day, turn the mains switch at the back of the UPS onto
OFF. If you don’t put the switch onto OFF-position the battery may be discharged
uncontrolled while the UPS is off.
5.3 Self-test of the UPS
You can use the self-test of the UPS to get a statement of the UPS function and battery
function. To start the self-test you have to push the push button ON/OFF during normal
operation of the UPS, i.e. mains voltage is existing, for the duration of less than 1 seconds.
After that the UPS starts the self-test. During self-testing the UPS works in battery-mode.
The LED „ Battery feeds load“ lightens. If the self-test was all right the UPS returns into
normal mode. The LED „Battery ON“ goes out and the LED „ Online“ lightens. In case of
failure the UPS turns back to online-operation and the LED „Change battery“ lightens up.
5.4 Switch-off of the alarm buzzer
If the built-in buzzer sounds, you can switch-off the alarm by pressing the push-button
ON/OFF for the duration of max. 1 second.
5.5 Cold start of the UPS
If the UPS is switched-off and there is no mains voltage, the quick-start can be done
anyway. For this you have to push the ON/TEST push button until the UPS emits a
bleeping sound.
