LOAD ON

BYPASS !

This message indicates that the load has been transferred to the bypass AC input (mains 2) source. The load is no longer protected.

BYPASS PROBLEM

CHECK FREQUENCY !

This message indicates that the bypass AC input (mains 2) source is out of frequency tolerance. The inverter has switched to free-running mode. Transfer of the load from the inverter output to the bypass AC input source requires an interruption of power to the load.

BYPASS PROBLEM

CHECK VOLTAGE !

This message indicates that the bypass AC input (mains 2) source is out of voltage tolerance. The inverter has switched to free-running mode. Transfer of the load from the inverter output to the bypass AC input source requires an interruption of power to the load.

INDEPENDENT INVERTER

FREQ. COMMAND ON !

This message indicates that the inverter has been set to free-running mode. The inverter is not synchronized to the bypass AC input (mains 2) power source. Transfer of the load from the inverter output to the bypass AC input source requires an interruption of power to the load.

BYPASS TRANSFER

LOCKOUT COMMAND ON !

This message indicates that the UPS has been set not to transfer from the inverter to the bypass AC input (mains 2) source. In the event of an inverter shutdown, the load will be disconnected.

BATTERY CABINET

OVERTEMP. !

This message indicates that the ambient temperature of the battery is out of tolerance.

UPS INPUT PROBLEM

CHECK FREQUENCY !

This message indicates that the main AC input (mains 1) frequency is out of tolerance. The rectifier/battery charger has shut down and the inverter is operating from its battery source.

UPS INPUT PROBLEM

CHECK VOLTAGE !

This message indicates that the main AC input (mains 1) voltage is out of tolerance. the rectifier/battery charger has shut down and the inverter is operating from its battery source.

CHARGER SHUTDOWN

COMMAND ON !

This message indicates that the rectifier/battery charger has been instructed to shut down, for example during progressive (stepped) transfer to a motor-generator set.
