2.8 Wiring, AC
hydraulic hoist
The AC wiring hoist is a stand-alone sys-
tem that does not require power from the sonar to
operate. It will operate independent from the sonar.
The hydraulic power pack is available 110V AC
signle phase and 220V AC single phase. Wiring is
the same for both systems.
2.8.1 AC hoist board wiring
1. The AC hoist board is enclosed in its own alu-
minum box. Before wiring, check the AC voltage
of the board. Next to transoformer T1 there will
be one or two jumpers installed. One jumper is for
220V AC and two jumpers are for the 110V AC
NOTE: Use a 30 amp slow blow fuse for 110V AC
and a 20 amp slow blow fuse for 220V AC.
2. Hoist board voltage.
Voltage to the hoist board is the same voltage that
will power the motor and the solenoid valve on
the hydraulic power pack. Run ships AC power
through one of the strain relief fittings on the hoist
box and connect the wires to TB3. Use wire size
capable to handle a one horsepower motor.
3. Hoist control cable, PN: 78.10015.0
The hoist cable is 25 feet (7.6 meters) long. One
end is terminated with a six pin connector, the other
end is terminated with terminal lugs. The connector
will mate with the connector on the switch panel
in the wheelhouse. The other end will go through
one of the small strain relief fittings on the hoist
control box. Connect each number wire to the same
numbered terminal on TB1.
If longer hoist control cable is needed, hoist exten-
sion cables are available in 25 feet (7.6 meters) in
length, PN: 78.10015.1.
