15 Set the hoisting/lowering switch S302 to Stop position.
Apply 3-phase AC power
You will now apply 3-phase mains power to the hull unit.
1 Reinsert the 3-phase mains fuses for the hull unit in the ship’s
fusebox.
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 10.
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 96.
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:
Hull Unit 230 Vac 380 / 440 Vac
SP70 3.4 A 2.4 A
SP71, SP72, SP73, SP74 10 A 6.5 A
SP75 5.5 A 4 A
5 Reinsert the 3-phase mains fuses for the hull unit in the ship’s
fusebox.
Functional check with power
The hull unit is now all powered up, and the final functional test
can take place.
