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
pre-attached to them for connection to the processor unit. Fabricate the power cable as
below. For the power cable, use DPYC-2.5 (Japan Industry Standard) cable or the
equivalent.
Note: For AC unit
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. Scrape off paint of the armor by 40 mm.
5. Cover the end of armor with vinyl tape.
