3.1.3. EMC-Correct Installation

Following these guidelines is advised, where compliance with EN 61000-6-3/4, EN 55011 or EN
61800-3
then it is acceptable to deviate from these guidelines. It is however not recommended.
Good engineering practice to ensure EMC-correct electrical installation:

First environment
is required. If the installation is in EN 61800-3
Use only braided screened/armoured motor cables and control cables.
The screen should provide a minimum coverage of 80%.The screen material must be
metal, not limited to but typically copper, aluminium, steel or lead. There are no special
requirements for the mains cable.
Installations using rigid metal conduits are not required to use screened cable, but the
motor cable must be installed in conduit separate from the control and mains cables. Full
connection of the conduit from the drive to the motor is required. The EMC performance
of flexible conduits varies a lot and information from the manufacturer must be obtained.
Connect the screen/armour/conduit to earth at both ends for motor cables and control
cables.
Avoid terminating the screen/armour with twisted ends (pigtails). Such a termination
increases the high frequency impedance of the screen, which reduces its effectiveness
at high frequencies. Use low impedance cable clamps or glands instead.
Ensure good electrical contact between the de-coupling plate and the metal chassis of
the frequency converter, see Instruction MI.02.BX.YY
Avoid using unscreened/unarmoured motor or control cables inside cabinets housing the
drive(s), where possible.
