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
Inverter Rated Output Current
≤ 24 A
3.3 INSTALLATIONS
ELECTROMAGNETIC COMPATIBILITY
Inverters with option C2 or C3 (MW500...C2...) feature internal RFI filter in order to reduce the
electromagnetic interference. Those inverters, when properly installed, meet the requirements
of the directive of electromagnetic compatibility (2014/30/EU).
The MW500 inverter 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. Inverter 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
Figure A.2 on page 199.
2. Shielded output cables (motor cables) with the shield connected at both ends, motor and
inverters, by means of low impedance for high frequency connection.
Maximum motor cable length and conducted and radiated emission levels according to
Table B.8 on page 210. If a lower conducted emission level and/or a longer motor cable is
desired, then an external RFI filter must be used at the inverter input. For more information
(RFI filter commercial reference, motor cable length and emission levels) refer to the
B.8 on page 210.
3. Shielded control cables, keeping the separations distance from other cables according to
Table 3.2 on page 21.
4. Grounding of the inverter according to instructions of
page 18.
5. Grounded power supply.
