2.4 Radar Processor Unit
Three cables are terminated at the radar processor unit: the antenna unit cable,
switching hub cable, and the power cable. Cables other than the power cable come
with a connector preattached to them for connection to the processor unit. Fabricate
the power cable as below. For the power cable, use DPYC-2.5 (Japan Industry Stan-
dard) Cable or the equivalent.
Note: For AC: Pass the AC line through a double-contact breaker (shipyard supply)
Fabricating the power cable
1. Cut armor of the cable by 40 mm.
2. Cut vinyl sheath by 35 mm.
3. Remove insulation of wires by about 10 mm. Fix crimp-on lugs to the cores.
4. Peel paint of the armor by 40 mm.
5. Cover the end of armor with vinyl tape (20 mm).
