INTRODUCTION
The BATTERY SAVER VHO is a power supply with transfer relays. Loads connected to the
BATTERY SAVER VHO are energized from the vehicle’s battery when the A.C. battery is OFF.
As soon as A.C. power is applied, the power supply provides 12 volts D.C. and the relay transfers
the loads to the power supply. Thus there is no drain on the battery and the entire output of the
vehicle’s battery charger is available to charge the battery.
INSTALLATION
1. MounttheBATTERYSAVERVHOinaconvenientlocationwith4 screwsinthemountingholes
provided. Be certain that adequate ventilation is available and that the unit is not subject to
water damage.
2. Connect the 120 volt A.C. input power to the BATTERY SAVER VHO through the 3 wire line
cord provided.
3. The low voltage connections are made to the terminal strip use 12 gauge wire, see wiring
diagrams .
4. The installation is now complete. If done correctly, the loads should be powered from the
battery when the A.C. power is OFF and from the power supply when A.C. power is ON.

supplied to the loads. This power should be coming through the BATTERY SAVER VHO.
Disconnect the wires to BAT 1,2 on the terminal strip and note that the loads are deenergized.
Leave the wire disconnected and apply 120 volts A.C. power to the vehicle. This should energize
the power supply and the loads. If the loads are energized, then the power supply is functioning
