Connecting Truck Electrics to the Diesel Engine Driven Compressor Unit
Electrical connection of SMAC to the truck is very simple. The entire control system is mounted in the
SMAC.
1.
The SMAC needs to be connected the truck battery. A minimum of 25mm cable is required for
the connection because the SMAC is started using the truck battery. SMACD units are 12 Volt
DC. If a truck is 24 Volt DC (Two of 12 Volt DC batteries are supplied in the truck), connection
for the SMAC Unit will be across 1 of the batteries.
2.
Start switch control box which includes the compressor load and unload switch needs to be
connected to the SMAC front panel via the Deutsch plug provided at the end of the 5-metre
cable of the control box. It should be noted; this switch box can be mounted in the cab of the
vehicle if an extension harness is purchased or any location on the truck body.
6.
Connection of the Diesel Engine Driven Compressor Unit to the fuel tank.
It is normal to use the trucks fuel tank for all models of the SMACD. The SMACD has as standard a fuel
pump built into it. It is suggested that an additional electrical fuel pump is installed if the compressor
unit is installed 20” (500 mm) above the height of the truck diesel tank. The following is the method for
connecting the fuel to the compressor unit.
1.
Cut the feed and return lines at the tank. Install the tees into the cut pipes.
2.
Install the provided check valve at the T-Piece of the feed pipe.
3.
Connect the diesel feed pipe to the compressor unit from the check valve. Connect the return
line from the compressor unit to the return line tee.
