Operation Modes

The display automatically indicates the current UPS operation mode. See the table below for examples of operation modes and their descriptions.

Operation mode descriptions:

Operation Mode	Description of Operation Mode

Normal Operation	The inverter supplies the load. The charger uses the mains supply to feed the
	inverter.

Battery Operation	The inverter supplies the load. The battery bank supplies the inverter. In battery
	operation the load support time is limited; when the batteries are discharged the
	UPS is unable to supply the load.

Bypass Operation	The bypass static switch supplies the load, meaning that the load is supplied
	directly from the bypass mains. When working in bypass operation the UPS can
	switch to battery operation if the bypass mains fails.

Charger Only	The charger is recharging the battery. The inverter is shut down.

Economy Operation	The UPS is in permanent bypass operation and will only switch to battery
	operation if the bypass mains is out of tolerance.

Hot Standby	In redundant configurations, one UPS can switch off the inverter, but still keep
	the inverter ready for immediate start in case another UPS fails.

In standby mode, the UPS has no output voltage.

Note

Users do not require electrical qualifications to switch the UPS to and from standby mode/normal operation.
