3.6 ELECTRICAL CONNECTION

3.6.1 DC POWER CABLE
The RADAR 3000 will work with any ship's mains within the 10.2 to 42 V
range, since it contains a power regulator circuit. Connect the power cable to a
DC source. The power cable normally should be wired through the circuit breaker.
The white lead wire of the power cable should be connected to the positive
source terminal and the black lead to negative source terminal. The shielded
wire should be connected to the ship's RF ground. Should the power connec-
tions be inadvertently reversed, a protective fuse will blow. Recheck the input
power leads for correct polarity with a VOM and reconnect the leads observing
correct polarity. Replace the fuse.
3.6.2 EXTERNAL SYSTEM INTERFACE
To connect with NAV-AID and/or compass, make sure pin as-
signment, if used same connector.
In case of different pin assignment, the RADAR 3000 or con-
nected NAV-AID will be damaged.
