switch / LED main function
1 - ‘on’ switch switches on the UPS, starts quick battery test (see 4.6)
2 - ‘off’ switch switches off the UPS
3 - LED ‘operation’ on when the UPS is operating
blinks if the UPS is in standby mode
4 - LED ‘on bypass’ on when the UPS operates in bypass mode: the incoming mains power is
channeled directly to the load
5 - LED ‘on battery’ on in case of battery operation: the mains power fails, and the internal
batteries supply the required power until either they are depleted or mains
power returns.
6 - LED ‘alarm’ blinks in case of an alarm
7 - LED bar ‘runtime capacity’ the remaining available battery runtime for the actual load, in % of the
maximum runtime with the actual load
8 - LED bar ‘load’ indicates to what extent the output capacity of the UPS is used by the
actual load. If e.g. the 25% and 50% LED are on, the load exceeds 50% of
the maximum load. If all 4 LEDs are on the unit operates in overload. As this
is an abnormal situation the alarm LED will blink as well.
