Wiring
Before connecting the motor to the power supply, it is necessary to connect the earth
wire. This is accomplished by using the terminals, which are in the terminal box and on
the motor frame. These terminals must be clean and protected from corrosion.
Properly sized wires must be used, both to connect the motor to the power supply and to connect the
earth wire, and they must conform to all applicable norms and regulations. It's recommended to
follow the specifications stated in the EN 60204 standard.
To connect the power supply, the wirings instructions here below must be followed exactly. For the
wirings of those single speed motors destined to USA and Canada, please follow up the additional
instructions.
After the connection is completed, check thoroughly the tightening of the terminals nuts. About the
wiring of the motors driven by an inverter, please follow up the inverter manufacturer instructions.
For the connection of the auxiliary devices (such as thermal protectors, heaters, forced ventilation and
so on) please consider the identification of the cables described in the relevant paragraph.
For the connection of the auxiliary devices (such as thermal protectors, heaters, forced ventilation and
so on) please consider the identification of the cables Brake coil is fed through a rectifier located
inside the terminal box (except for the 24V DC brake).
The AC side rectifier supply is stated on motor name plate. Rectifiers can be equipped either with type
Q or type M. For connections, diagrams Q and M are to be followed.
In the motors supplied with a 24VDC brake the rectifier is not supplied. In case of whatever difficulty
please contact us.
When switching the electromagnetic group on DC side it is useful to protect the contacts from burn
out (RC device or free-wheeling diode)
