Motor connection
An expert electrician must always carry out the electrical connection. Compare the power
supply with the data plate specifications and then choose a suitable connection. The type of
connection is stated on the motor data plate and can be Y (star) or D (Delta), according to the
power supply of the motor (see figure below).
STAR
DELTA
Follow the connection standard used in the plant. In no case connect the electrical motor
directly to supply network but use a suitable electric switchboard equipped with a knife switch
and suitable safety devices (e.g. motor breaker switches) in the power circuit. Safety devices
against overloads must also protect the motors. Make sure that the motor has suitable
grounding and that it has been connected properly.
