3.6 ELECTRICAL CONNECTION
3.6.1 DC POWER CABLE
The RADAR 2000 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.
FIG. 3-4 SCANNER UNIT CABLE CONNECTION PROCEDURE
3.5 CONNECTING THE SCANNER UNIT CABLE
Step 1. Loosen the 4 clamping bolts se-
curing the radome and remove the
radome cover.
Step 2. Remove watertight gland where
the interconnect cable enters the
scanner.
Remove the cable clamp and 2
screws.
Step 3. Add the rubber grommet and in-
sert the connecting cable. Secure
the watertight gland.
Step 4. Connect the cable leads to termi-
nal board TB1 and J1. Ground the
shield with the lug to cable clamp
bolt provided. Dress the wire har-
ness with cable clamps or tie-raps
as necessary for neatness.
