Connecting power cables
6.8.1
Preparations
When connecting the cables, observe all the conditions regarding conductor protection. Do not
exceed the permitted cable lengths between the converter output and motor. The distance
between the motor cable and the signal cable should be at least 20 cm. Do not lay grid-side and
motor supply cables in parallel to each other.
The positions of the connections are shown in the layout diagrams. Detailed wiring notes for the
converter are contained in the circuit manual of the converter.
Select the appropriate cable depending on the following conditions:
● Routing conditions
● Accumulation of cables
● Ambient temperature
● Bending radii
● Output voltage
Observe the connection capabilities on the converter and on the motor terminal box.
Detailed information about cabling of the converter is provided in the circuit diagrams supplied.
● Please ensure that the maximum cable lengths between the converter and motor are not
exceeded.
● Make sure that the permissible cable capacitance is not exceeded.
● Use appropriate screws for the cable lugs provided.
● The tightening torque for the M12 screws is 50 Nm.
● Clean the contact surfaces before screwing the connections.
● Apply a thin layer of grease to the screws.
