INTRODUCTION
The BATTERY SAVER 75 is a power supply with transfer relay. Loads connected to the BATTERY
SAVER 75 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. Mount the BATTERY SAVER 75 in a convenient location with 4 screws in the mounting holes
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 75 through the 3 wire line cord
provided.
3. The low voltage connections are made through 3 wires
a. Connect the "BAT" wire to the vehicle's 12 volt system.
b. Connect the "LOAD" wire to the 12 volt electrical loads.
c. Connect the "GROUND" wire to the vehicle's ground or the battery (-).
4. The installation is now complete. If done correctly, the loads should be powered from the battery
when the A.C. power OFF and from the power supply when A.C. power is ON.
TEST
To test the installation first remove A.C. power from the vehicle. Now determine that power is being
supplied to the loads. This power should be coming through the BATTERY SAVER 75. Disconnect
the "BAT" wire input and note that the loads are deenergized. Leave the "BAT"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 correctly. THE TEST IS
NOW COMPLETE. Now reconnect the "BAT"wire. This is important!
