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.
Note
To route the power cables from above into the cabinet, remove the cover plate at the top of
the cabinet.
