CONNECTION TO POWER
The MCX-2 control panel is illustrated above. Note that the bottom of all three selector
switches has been pressed which turns all functions off. Make sure all switches are
off before connecting the battery cable clips to the battery of the vehicle.
WARNING: Handle battery connection cable with extreme caution. Batteries
generate explosive gases during normal operation. Working in
the vicinity of a lead-acid or other automotive battery is
dangerous. Wear eye protection. Never smoke or allow a spark or
flame in the vicinity of the battery. Do not connect the black
power clip to the negative post of the battery to avoid a spark.
1. Verify that all switches are in the off position.
2. Connect the red power clip to the “+” (positive) post of the vehicle battery. The
battery must be 12 volt.
3. Connect black power clip to an engine ground (not the negative post of the
battery).
