5.3.3 Transferring the load to bypass
During normal operation, the load is supplied with power from the inverter. The inverter voltage is
controlled and regulated to protect the load from any aberrations in the local ac power. When the load is on
the inverter, battery backup is always ready to ensure a continuous power supply even in the event of a
local ac power failure.
Transferring the load to bypass takes the load off the regulated voltage of the inverter and supplies the
load with power directly from the local ac mains. In bypass mode, no power conditioning is in effect, and in
the event of an ac mains failure there is no battery backup to supply the load. Transfer to bypass can occur
automatically, when the controller detects a malfunction in the inverter or a short-circuit in the load. Transfer
to bypass can also be accomplished manually.
To manually transfer the load from the inverter to the bypass power:
Main Menu > Operation > Transfer load > Transfer Load to Bypass > OK
5.3.4 Transferring the load to the inverter
To transfer the load from bypass power to inverter power:
Main Menu > Operation > Transfer load > Transfer Load to Bypass > OK
See section 5.3.3 above for an explanation of the difference between inverter mode and bypass mode.
