2.3 Monitor Unit (for FAR-2167DS)
Two cables are terminated at the monitor unit: the signal cable from the processor unit (5 m or 10
m cable) and the power cable from the ship's mains. The signal cable comes with a connector pre-
attached to it for connection to the monitor unit. Fabricate the power cable as below. Use DPYC-
2.5 (Japan Industry Standard) cable or the equivalent. Be sure to ground the unit, with IV-8sq wire
(local supply).
Note: Pass the AC line through a double-contact breaker (shipyard supply). Further, for vessels
where the power line is grounded, connect one end of the line to the C (common) terminal and the
other end to the H terminal.
Fabricating the power cable DPYC-2.5
1. Remove the armor from the cable by 40 mm.
2. Remove the vinyl sheath by 35 mm.
3. Remove the insulation from the cores by about 10 mm..
4. Peel paint from the armor by 40 mm.
5. Cover the end of the armor with vinyl tape. Fix crimp-on lugs (FV5.5-4, yellow) to the cores.
