Manual Load Transfers
A manual load transfer between the UPS750 output and the alternate bypass AC source can be initiated from the UPS750 control panel. Manually initiated transfers are "make-before-break". These transfers utilize the UPS750 output and the system bypass circuit breakers.Automatic Load Transfers
Automatic load transfers between inverter outputs and alternate bypass AC source are initiated when the either of the following conditions are met:
A malfunction that would affect the output voltage.
An overload condition is sustained for a time period in excess of system output capability. Transfers that are caused by overloads initiate an automatic retransfer of the load back to the system, only after the load has returned to a level within the rating of the UPS750. The system logic of the UPS750 allows the load to be transferred up to three times. The system will be locked out in bypass mode on the fourth transfer.
