7.4.2 Cabling Requirements
1) The motor cables must be laid far away from other cables. The motor cables of several
AC drives can be laid side by side.
2) 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 AC drive, the motor cables and other cables must not be laid side
by side for a long distance.
3) If the control cable must run across the power cable, make sure they are arranged at
an angle of close to 90

4) The power input and output cables of the AC drive and weak-current signal cables
(such as control cable) should be laid vertically (if possible) rather than in parallel.
5) The cable ducts must be in good connection and well grounded. Aluminium ducts can
be used to improve electric potential.
6) The filter, AC drive and motor should be connected to the system (machinery or
appliance) properly, with spraying protection at the installation part and conductive
metal in full contact.
