INTRODUCTION
The BATTERY SAVER HO is a power supply with transfer relay. Loads connected to the
BATTERY SAVER HO are energized from the vehicle’s battery when the A.C. battery is OFF. As

battery charger is available to charge the battery.
INSTALLATION
1. Mount the BATTERY SAVER HO in a convenient location with 4 screws in the mounting holes
provided. Becertain that adequateventilation is availableand that theunit is not subjectto water
damage.
2.Connectthe120voltA.C.inputpowertothe BATTERY SAVER HO throughthe3wireline cord
provided.
3. The low voltage connections are made to the terminal strip use 14 gauge wire, see wiring
diagrams .
4.Theinstallationisnowcomplete. Ifdonecorrectly,theloadsshouldbepoweredfromthebattery
when the A.C. power OFF and from the power supply when A.C. power is ON.
TEST
TotesttheinstallationfirstremoveA.C.powerfromthevehicle. Nowdeterminethatpowerisbeing
supplied to the loads. This power should be coming through the BATTERY SAVER HO.
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
correctly.THETESTISNOWCOMPLETE.NowreconnectthewirestoBAT1,2ontheterminal
