INSTALLATION INSTRUCTIONS
1. Mount the SBI12-LLD securely in a convenient location near the auxiliary
battery bank. Do not mount in direct engine heat.
2. Install in the order described below:
ƒ Make sure the auxiliary battery negative is properly grounded to the vehicle
chassis.
ƒ Ground connection. Connect the SBI12-LLD ground terminal to chassis
ground. Remove any paint to ensure a good ground connection.
NOTE: A good connection will ensure correct switching voltage.
ƒ Select correct circuit Breaker/Fuse sizes and install at battery end of the
positive cable.
ƒ LED Connections (optional). Connect a wire from the Blue wire of the
SBI12-LLD to the positive end of an indicator LED (15 mA limited current
draw) or LED/resistor combination.
ƒ Override Feature (optional). Connect a wire from the Blue wire of the SBI12-
LLD to one terminal of a momentary push button switch. Connect the
other terminal of the momentary push button switch to the auxiliary battery
supply. To manually operate the Load Disconnect Isolator (force the loads
to stay connected below the cut off voltage), hold the momentary push
button and the Isolator will manually operate until the switch is released.
STANDARD WIRING DIAGRAMS
ƒ Ensure adequately sized cable is used.
ƒ Ensure the auxiliary battery is properly grounded to a common chassis
earth point.
ƒ Ensure the SBI12-LLD ground wire is making good contact with the chassis
ground point.
ƒ When using fuses make sure that the fuse makes a good low resistance
connection.
ƒ Fuse/Circuit Breaker ratings are dependent on the type of installation and
the size of the loads.

Care should be taken not to excessively discharge the auxiliary battery.
ƒ Checking the operation: The SBI12-LLD should now be operational.
Once the auxiliary battery voltage rises to the 'ON' voltage the SBI12-LLD
will activate, you will hear the solenoid click and see the LED illuminate.
Discharge the auxiliary battery. The SBI12-LLD will disconnect load from
the auxiliary battery once the voltage on the auxiliary battery drops to the
'OFF' Voltage; the solenoid will make an audible click and the LED will
go out.
CAUTION: Over discharge risk. Ensure that the Turn OFF Voltage is
suitable for the specifications provided by the battery manufacturer.
NOTICE:
ƒ It is normal for the LED to stay ON whenever the auxiliary battery is in a
condition suitable for running loads.
ƒ The amount of time it takes for the battery voltage to drop low enough
for the solenoid to turn off will vary due to battery condition, age and
state of charge.
