Power Connection

CAUTION:

If the power connections are accidentally reversed the system will not work. Use a multimeter to ensure that the input power leads are connected for correct polarity.

Switch off the display unit before you remove the power cord.

The RED wire must be connected to the feed from the positive (+) battery terminal and the BLACK wire to the feed from the negative (–) battery terminal. The shielded wire (screen) should be connected to the ship’s RF ground as previously described in Grounding the System on page 8-12.

Any unused wires should be insulated and taped back.
