A.4.2 System Wiring Requirements
1) The motor cables must be far away from other cables. Recommended distance is
bigger than 0.5 m. The several controllers can be laid in parallel.
2) It is recommended that the motor cables be protected in the metal sheathing or
cabling duct with metal plate; both sides of the metal jacket and cabling duct
must be grounded reliably.

3) 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. It is recommended that the motor cables, power input
in good connection and well grounded.
4) If the control cable must run across the power cable, make sure they are arranged
at an angle of close to 90° . Do not run other cables above the controller.
5) The power input and output cables of the controller and weak-current signal
cables (such as control wires) should be laid vertically (if possible) rather than in
parallel.
6) The cable trunking must be in good connection and well grounded. Aluminum
trunking can be used to improve electric potential.
7) The controller must be in good contact with the control cabinet. The contact area
is coated to ensure good conductivity.
8) The motor must be in good contact with the system. The contact area is coated to
ensure good conductivity.
