It is recommended that all control cables be shielded.
•
It is recommended that a shielded cable be used as the output power cable of the AC
drive; the cable shield must be well grounded. For devices suffering from interference,
shielded twisted pair (STP) cable is recommended as the lead wire and the cable shield
must be well grounded.
8.4.3 Cabling Requirement
1. The motor cables must be laid far away from other cables, with recommended distance
larger than 0.5 m. The motor cables of several controllers 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 controller, 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°. Other cables must not run across the controller.
4. The power input and output cables of the controller 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, controller 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.
7. The controller must be connected to the cabinet properly, with spraying protection at the
installation part and conductive metal in full contact.
8. The filter must be connected to the cabinet properly, with spraying protection at the
installation part and conductive metal in full contact.
9. The motor should be connected to the system (machinery or appliance) properly, with
spraying protection at the installation part and conductive metal in full contact.
