To connect to both an AC and DC ship’s mains, the optional AC-DC power supply unit
PR-300 (FS-1575) or PR-850A (FS-2575/FS/5075) is required. Attach the crimp on
lug FV5.5-4 (local supply) to the following cables or equivalent (local supply) for con-
nection with the power supply unit.
• AC power: DPYC-6
• DC power: DPYC-6 (FS-1575), DPYC-10 (FS-2575), DPYC-16 (FS-5075)
How to process power cables
Fabricate the cable as shown below. Connect cables to their input terminals with
crimp-on lugs.
How to select input voltage
