Connections for the line supply, motor and DC link terminals
Rules for connecting the line:
● Only use the front connections.
● You may connect 1 or 2 cables to each of the screws of the line connections.
Rules for connecting the motor:
● First use the front connections.
● If you use more than one cable per connection: Distribute the cables per connection evenly
on the left and right side of the connection.
● Only use the rear connections when the front connections are occupied.
After the cables are connected, you must re-attach the covers in order to re-establish the touch
protection of the converter (screw tightening torque: 6 Nm/53 lbf.in).
WARNING
Electric shock if the cable entry protection cover is not cut correctly
A cable entry protection cover which is not cut correctly may lead to dangerous touch voltage
which can result in serious injury or death.
● Make proper openings on the cover according to the required cable diameter in order to
ensure degree of protection IP20.
