C.3 Cables
C.3.1 Power cables
The sizes of the input power cable and motor cable must meet the local regulation.
Note: If the conductivity of the motor cableshield layer cannot meet the requirements,
separate PE conductors must be used.
C.3.2 Control cables
All analog control cables and cables used for frequency input must be shielded cables.
Relay cables need to be those with metal braided shield layers.
Keypads need to be connected by using network cables. In complicated electromagnetic
environments, shielded network cables are recommended.
Note:
 Analog signals and digital signals cannot use the same cables, and their cables must be
arranged separately.
 Check the insulation condition of the VFD input power cable before the connection.
