Make sure all metallic parts in
contact with saltwater are properly
grounded and bonded properly to the vessel's
bonding system. Failure to follow these
instructions will void the warranty.
>
Each a/c unit installed requires a dedicated
circuit breaker. For installations of two or more
units sharing the same pump, the pump wires
will be connected to a pump relay panel (PRP),
which in turn has its own dedicated circuit
breaker sized for the pump (20 A max).
>
Electrical connections in the bilge and/or
below the waterline should be sealed with heat
shrink type butt splices.
>
Field wiring must comply with ABYC
electrical codes. Power to the unit must be
within the operating voltage range indicated
on he data plate. Properly sized fuses or HACR
circuit breakers must be installed for branch
circuit protection. Refer to the data plate for
max fuse/circuit breaker size (mfs) and
minimum circuit capacity (mca).

Electrical Connections
The following must be observed when making the electrical connections:
1.
In accordance with ABYC standard E-8, or equivalent, the Alternating
Current (AC) ground (green wire) must be connected to the ground
terminal (marked "GRND") on the AC input terminal block of the unit(s)
for supply.
2.
Connections between the vessel's AC system grounding
conductor (green wire) and the vessel's Direct Current (DC)
negative or bonding system should be made as part of the
vessel's wiring, per ABYC standard E-9, or equivalent.
3.
When servicing o replacing existing equipment that
contains a chasis 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.
Figure 12 shows the Standard U-Board. Figure 13 shows the Soft-Start U-
Board.
