1.6 Wiring

Wiring considerations

• Turn the power at the switchboard off before beginning the wiring.

• Insert the 10 A fuse to the fuse holder (supplied with the cable assembly) when in-

stalling with 15 m, 20 m and 30 m cables. When installing with 10 m cables, the fuse

to be used will be different according to the voltage of ship’s main. Use the 15 A fuse

for 12 VDC ship’s main. Use the 10 A fuse for 24 VDC ship’s main. Also, attach the

supplied fuse rating label to the fuse holder. For details, see “How to Replace the

Fuse” (C32-01604).

• The cable assembly and power/LAN cables have connector(s). Do NOT cut the ca-

ble assembly and power/LAN cables even if the cables are run through a radar

mast.

• When you replace the DRS4A/6A/12A/25A with the DRS6A-NXT/DRS12A-NXT/

DRS25A-NXT, the existing cable cannot be used. Use only the cable assembly sup-

plied with this radar sensor.
