Control Circuit Wiring
● Cable selection for control circuit
Use copper conductors of a proper size as control cables according to the recommended
values in Table 4-2.
● Cabling requirement of control circuit
The motor cables must be laid far away from all control cables.
It is recommended that the motor cables, power input cables and control cables be laid in
different ducts. To avoid electromagnetic interference caused by rapid change of the output
voltage of the controller, the motor cables and other cables must not be laid side by side for a
long distance.
If the control cable must run across the power cable, make sure they are arranged at an angle
of close to 90°.
The following gure shows the recommended cabling diagram.
