10 Set the hoisting/lowering switch S302 to Hoist position,
and check that the hoisting contactor K301 is activated
when pressing the hand crank safety switch S303.
11 Set the hoisting/lowering switch S302 to the Lower
position and check that the lowering contactor K302 is
activated when pressing the hand crank safety switch
S303.
12 Set the hoisting/lowering switch S302 to the Stop
position.
13 Place the hand crank back into its storage position in the
Motor Control Unit.
14 Activate the hoisting contactor K301 by setting the
hoisting/lowering switch S302 to Hoist position, and
check if the contactor is deactivated when pressing the
upper limit switch S304 upwards.
15 Activate the lowering contactor K302 by setting the

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.
→ General safety ryles, 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.
