Special Requirements for Marine Installations:
These refrigerators are internally wired so that the AC and DC circuits are isolated from each other. If the positive
(+12/24 volts) input is grounded (by cuts in the wire insulation, incorrectly insulated components, etc.) a voltage
potential can be caused throughout the boat, which causes corrosion to form on any metal parts that are exposed
to water.
This condition can be avoided by wiring the boat so that the AC and DC grounds are common and so the wiring is
protected per NNMA CERTIFICATION HANDBOOK (1987). Inspect all wiring to make sure that the insulation is
not damaged and use plastic wire clamps.
