8.4 – Power supply
Before undertaking any operation on the electrical unit, check that the power supply to the
machine is off.
A disconnecting switch must be placed no more than 10 metres from the place of use.
Very important: the winch will only provide full power if the motor is supplied via a cable
section which is perfectly suited to this use.
Provide protection for individuals in front of the electrical unit.
8.4.1 – Electrical connections
The power supply cable, the protective fuses and the main disconnecting switch (see
wiring diagram) must be provided by the customer.
Check that the supply network complies with the machine.
Check the type of current; there must not be more than about 5% deviation from the
rated voltage
Neutralise electrical sources
Check that the main power supply switch on the winch is in the off position.
Do not connect the power supply cable to the machine using connection terminals (split
fittings etc.)
Do not use a cable with a smaller section to supply power to the machine. Power supply
via a generator is possible:
-
Minimum power of 3.75 kVA according to the models 250 and 400 kg.
-
Minimum power of 5,5 kVA according to the models 1000 kg.
Never "shunt" the disconnecting switches, electrical switches, prevention or limitation
equipment.
Never block, adjust or remove switches or end stops in order to go beyond the levels that
they allow.
A disconnecting switch must be placed no more than 10 metres from the place of use.

8.4.2 – Connection
Connect the power supply using the single phase or three phase male connector supplied
using about 0.5 m of power supply cable.
Check that the winch works (direction of rotation)
Do not change the direction labels in the control unit or in the winch's internal wiring.
8.5 – Work rope
Important: the direction of rotation of the drum depends on the way in which the machine is
connected (order of the three-phase current phases)
Reminder: check the maximum capacity of the winch
Very important:
The safety regulations require that 2 to 3 coils of rope always be left on the drum.
To comply with the legislation, the rope diameter must not exceed the recommended
diameter.
If the rope and the hook used were not supplied with the machine by the manufacturer, check
that they guarantee a level of safety corresponding to table § 6.5.
When the winch is supplied with the rope wound on, it has not been tautened during assembly.
