The SC40 is supplied with a 30 AMP Circuit Breaker, Crimp Terminals and mounting screws, Heavy Duty 2 Way 8mm Plug, Socket and Terminals and Installation Instructions for fitting the Controller. All that is needed is a few meters of heavy automotive cable.
There are two primary objectives carried out by the SC40.
In the MAIN operating mode, the first and most important objective of the SC40, is to protect the vehicle's main battery against being discharged bellow a point at which the battery would not be able to start the vehicle.
The second primary objective of the SC40 is that after the vehicle is started, the SC40 will make sure that the main battery has a sufficiently high enough charge voltage going to it before starting to charge the auxiliary battery.
Also, if the main battery fails during operation of the vehicle, when the motor is stopped and the voltage drops, the SC40 will isolate the two batteries from each other, thus preventing the auxiliary battery from being discharged by the faulty main battery. When it is time to start the vehicle, a set of jumper leads can be used between the auxiliary battery and the main battery to get the vehicle started.

After turning the vehicle's ignition off, most vehicle batteries are capable of supplying some of there stored power for other uses and still have enough charge left to be able to start the vehicle, the SC40 allows this additional power to be used thus giving your auxiliary battery on average, around 50% more operating time and this usually gives you a longer time beforebefore you have to charge the auiliary battery again This makes the SC40 ideal for all you Weekend Worriors.
So while there is extra power available at the main battery the SC40 shares the load between the main battery and the auxiliary battery and in doing this, the operating time for the accessories running off the auxiliary battery is extended but at the same time the SC40 will still automatically safe guard the main battery from over discharging.
The SC40 is quick and easy to fit with an average installation taking about 45 minutes. Once installed, the operation of the SC40 can be monitored by checking the indicator LED on the front of the SC40.
When the LED is flashing, the SC40 is off and the main battery is isolated and when the LED is glowing constantly, the SC40 is operating and has both batteries connected together.
