Always refer to the wiring diagram that is specific to the unit that you bought
shipped with the unit). If it is not on the unit or has been lost, contact the salesperson of reference
who will send a copy (specify the unit's serial number).
Before connecting the electrical panel, make sure that:
• the voltage and frequency of the network correspond to the parameters of the unit.
• the electrical system being connected has sufficient capacity to supply the nominal electric power of
the unit to be installed and meets current regulations.
The electrical connection must be:
• made by qualified personnel after cutting off the facility's power supply;
• Performed in a fixed and permanent manner, without intermediate splices, in compliance with the
regulations of the country of installation;
• adequate to the absorption of the unit (see technical specifications);
• provided with a functioning grounded plug. For multiple units it is necessary to connect each unit to
the ground connection or combine them all with metal ties.
• preferably situated in a dedicated room,
switch, the key must be removed when cutting the power supply and returned to its position only after
finishing service operations.

nominal values.
After connecting, make sure that:
• the ground connection is sufficient (using the appropriate instrument). An incorrect connection, inef-
fective and lacking the grounding circuit, is contrary to safety regulations and is a source of danger and
can damage the components of the unit.
• the motor rotation direction is correct;
• the wiring and motor power draw are correct.
