Switch
1. Turn on UPS system:
By pressing the ON-Switch
ON - Switch
2. Deactivate acoustic alarm:
By pressing this switch an acoustic alarm can be deactivated.
When mains power is normal, the UPS system switches to Standby mode
by pressing OFF-Switch
inverter is off.
OFF-Switch
At this moment, the output sockets are supplied with voltage via the bypass
if the mains power is available.
Display
1. The green LINE LED lights up if mains voltage is applied to the
UPS input.
2. LINE LED blinks when the phase and neutral conductor have been
LINE LED
reversed at the input of the UPS system.
3. If LINE LED and BATTERY-LED light up, the mains power supply
is out of tolerance.
The orange-coloured BATTERY -LED lights up when the mains power has
BATTERY LED
failed and the inverter is being powered by the batteries.
The orange-coloured BYPASS LED lights up when the UPS system is
BYPASS LED
supplying voltage provided by the mains power via the bypass.
The green-coloured INVERTER LED lights up if the UPS system is
INVERTER LED
supplying voltage provided by the mains power via the inverter.
The red FAULT LED lights up and an acoustic warning signal is issued
FAULT LED continuously when the UPS system is in fault condition. Press the Standby
switch in order to turn off the warning tone.
