Four cables are terminated at the processor unit: the antenna unit cable, display unit cable, control unit 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 Standard) cable for AC unit or DPYC-6 for DC unit, or the equivalent.

Note: For AC unit

Pass the AC line through a double-contact breaker (shipyard supply).
