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.
1. Screw the protective ground at the provided locations in the cabinet to the appropriate
connection with the ground symbol.
Note
Connect the motor cables first and then the power cables.
2. Connect the infeed cable to the supply-system connection busbar.
