2.0 System Operation
The SSC3 is controlled by a positive DC voltage on INPUT terminal. The turn ON voltage is +8.0 Vdc (Range of +8.0
to 18.0 Volts). The turn OFF voltage is <+4.0 Vdc.
Note that the input voltage must drop to under +4.0 volts, then
increase to +8.0 volts to turn on again.
Certain fault conditions will cause the power switch to turn off and the LED to start blinking. The SSC3 will remain
latched off until the fault(s) are cleared, the INPUT voltage removed, then the INPUT voltage re-applied.
The fault conditions that the SSC3 will recognize include:
1. Over-current condition for greater than 1 Second.
2. Loss of ground
3. Under-voltage
4. Over-voltage
5. Over-temperature
6. Shorted Load Detection

4.0 Installation Procedure
Do not weld on the vehicle with the SSC3 installed and connected as damage to the product may result. If electric
welding is necessary, disconnect the control INPUT terminal, and the cables attached to the LOAD and BAT+ terminals.
Damage due to electric welding while the unit is installed will void InPower’s warranty.
