Connect the power cable to the motor and the supply system

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.
Procedure
1. Open the cabinet.
2. Remove or slide away the cover plate for the motor cable penetration.
Cable fire caused by high transition resistances
Cables connected to the connection point that are not in compliance with the applicable
regulations represent a high electrical transition resistance that can cause thermal damage
(fire) during operation.
● Tighten the screws with the required torque.
