11. ELECTRICAL CONNECTIONS
Before making the electrical connecons, installers MUST make sure
that the mains voltage matches the technical specicaons and the
data on the winch idencaon plate.
All electrical connecons must be made with the main
switch in the OFF posion.
Make sure that the rated supply voltage is maintained
at all mes.
If they match, connect the electric motor.
1 ELECTRIC MOTOR
Using the wiring diagram (which can be found in the motor terminal box), make the electrical
connecons and make sure that you connect the phases and earth correctly.
IMPORTANT NOTE
Any thermistors on the motor MUST BE CONNECTED TO A
SPECIFIC RELAY ONLY.
Incorrect connecon of the thermistors will burn them out
immediately.
2 AUXILIARIES
Connect any auxiliaries by referring to the wiring diagram placed
under the terminal box cover or enclosed with this manual.
Check that the tension of the installed brake corresponds to that of
its dedicated charger, check that the coil connecons correspond to
those indicated in the diagram under the terminal board cover. The
installer is responsible for providing a suitable surge suppressor to
protect the brake coil.
Please also remember to check the fan voltage and power frequency.
Aer connecng, close the terminal box.
In any motor conguraon, always connect the correct
voltage (V~) to terminals 9U2, 9U3 of the fan.
