4.2 Safety Precautions
This product requires the installer to be trained for installation and work on vehicle electrical systems. We
recommend that all wiring meet the SAE and applicable vehicle manufacturer’s wiring specifications. Inspect
the product and all other components for damage before starting the installation. Do not perform the installa-
tion if any problems exist.
Make sure that the vehicle battery power is disconnected during installation of the solid state contactor.
Reconnect the battery when the installation is complete. Wear appropriate safety equipment such as eye-
glasses, face shield and clothing when installing the equipment and handling the battery. Be careful when
working near a battery or loads with high current conductors. Make sure the area is well ventilated and that
there are no flames near the battery. Never lay objects on the battery that can short the terminals together or
to ground. If battery acid gets in your eyes immediately seek first aid. If acid gets on your skin immediately
wash it off with soap and water.
4.3 Mounting Location
First determine where the contractor will be mounted. We recommend mounting it to a flat metal surface
that can absorb heat produced by the contactor. Also take into consideration the maximum current needed
and the maximum mounting surface temperature (See Specification Section).
The SSC3 should not be
mounted in the engine compartment or any location near the engine’s heat.
For maximum thermal ef-
ficiency the mounting surface should be a thick metal surface such as an aluminum plate 1/8 x 16 x 16 inches
or larger.
To facilitate heat transfer, please apply a thin layer of silicon thermal material (user supplied) to the metal
plate on the bottom of the SSC3. Smooth this out with a flat edge to insure there are no gaps Secure the
contactor to the flat metal surface using four screws and tighten to a torque setting of 5 inch pounds.
Do not
drill out the contactor’s four mounting pad holes to use a larger bolt size.
4.4 Connect the GND
Proper operation of the SSC3 is dependent on a good quality ground system with appropriate sized wires for
connection to the chassis battery and the load. For the grounding of the SSC3, be wary of attaching to the
frame since many manufacturers only recommend grounding directly to the Engine Block as a guaranteed
ground. Consult the recommended grounding documentation for your vehicle.
Install a #16 AWG ground wire with a ring terminal and connect it to this good quality ground. Place this on
the GND terminal and torque
the
brass nuts on the 8/32 screw terminal to 4 - 5 Inch Lbs
.
4.5 Connect the POWER CABLES and Control INPUT
Prepare the cables to the battery and auxiliary load using a appropriate size cable for the current required.
Install a double crimped (or 360 degree crimped) lug terminal on the ends. BAT+ terminal is connected to the
positive feed from the chassis battery and LOAD terminal is connected to the auxiliary load(s).
To connect the control voltage to the INPUT terminal, install a #16 AWG ground wire with a ring terminal, and
connect that to a 12V control voltage. This can be a switch or voltage source of your choice such as the IG-
NITION signal. Refer to the input voltage specifications for this interface.
Place the ring terminal on the GND
terminal and torque
the
brass nuts on the 8/32 screw terminal to 4 - 5 Inch Lbs
.
