Cable Separation Distance; Installations According To European Directive Of Electromagnetic Compatibility; Conformal Installation - WEG MW500 User Manual

3.2.7 Cable Separation Distance

Provide separation between the control and power cables and between the control
cables (relay output cables and other control cables) as per
Drive Rated
Output Current
≤ 24 A
3.3 INSTALLATIONS ACCORDING TO EUROPEAN DIRECTIVE OF
ELECTROMAGNETIC COMPATIBILITY
Drives with option C2 or C3 (MW500...C2...) feature internal RFI filter in order to reduce
the electromagnetic interference. Those drives, when properly installed, meet the
requirements of the directive of electromagnetic compatibility.
The MW500 drive series was developed for professional applications only. Therefore,
the emission limits of harmonic currents by the standards EN 61000-3-2 and
EN 61000-3-2/A 14 are not applicable.

3.3.1 Conformal Installation

1) Drive with optional internal RFI filter MW500...C2... (with grounding switch of the
capacitors of the internal RFI filter in the position ON). Check the installation of the
grounding screw in
2) Shielded output cables (motor cables) with the shield connected at both ends, motor
and drives, by means of low impedance for high frequency connection.
Maximum motor cable length and conducted and radiated emission levels according
to table B.3. If a lower conducted emission level and/or a longer motor cable is desired,
then an external RFI filter must be used at the drive input. For more information (RFI
filter commercial reference, motor cable length and emission levels) refer to the
B.3.
3) Shielded control cables, keeping the separations distance from other cables according
to table 3.2.
4) Grounding of the drive according to instructions of
5) Grounded power supply.
