Auxiliary Power Supply

You may use an auxiliary power supply to keep the 700S Control Assembly

Board, DriveLogix controller and any feedback option cards to continue
operation. Connect auxiliary power to J15 on the Fiber Optic Interface
board. You must set parameter 153 [Control Options], bit 17 “Aux Pwr
Sply” to enable this feature.
