Operating instructions

Grounding/Bonding

All Cabin Comfort Series air conditioning units must be effectively grounded to minimize the

hazard of electric shock and personal injury.

The following are to be observed:

1. AC (alternating current) grounding (green wire) must be provided with the AC power

conductors and connected to the ground terminal (marked “GRND) at the AC power

input terminal block of the unit(s), per ABYC standard E-8, or equivalent.

2. Connections between the vessel’s AC system grounding conductor (green wire) and the

vessel’s DC (Direct Current) negative or bonding system should be made as part of the

vessel’s wiring, per ABYC standard E-9, or equivalent.

3. When servicing or replacing existing equipment that contains a chassis-mounted

“ground” stud, the service person or installer must check the vessel’s wiring for the

existence of the connection required in item 2 above.
