2 Measure the three-phase voltage on the terminals of the
motor overload switch
S301 in the motor control unit.
- Write down the measured voltage here:
Supply voltage (Vac):
WARNING The mains voltage is lethal. Observe the safety
precautions described in the general safety
rules.

Refer to page 9.
Re-wire for 230 Vac 3-phase
The hoist/lower motor is normally pre-wired for 380 / 440 Vac
three-phase. If the measured three-phase voltage is 230 Vac, the
motor must be rewired.
1 Remove the 3-phase mains fuses for the hull unit in the ship’s
fusebox.
2 Remove the cover for the mains connection to the motor.

Refer to figure 33 on page 94.
3 Rearrange the motor connections so that they correspond to
the measured voltage.

4 Adjust the release current on the motor overload switch S301
according to the three-phase voltage:
•
230 Vac: 5.5 A
•
380 / 440 Vac : 4 A (minimum)
