3.2.6 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

≤ 24 A
≥ 28 A
3.3 INSTALLATIONS ACCORDING TO EUROPEAN DIRECTIVE OF
ELECTROMAGNETIC COMPATIBILITY
Inverters with the option C2 or C3 (CFW500...C...) feature internal RFI filter to reduce the
electromagnetic interference. Those inverters, when properly installed, meet the requirements
of the directive of the electromagnetic compatibility.
The CFW500 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

2. Shielded output cables (motor cables) with shield connected at both ends, motor and inverter,
by means of a low impedance to high frequency connection.
Maximum motor cable length and conduced and radiated emission levels according to
B.3 on page 151. For more information (RFI filter commercial reference, motor cable length
and emission levels) refer to the
3. Shielded control cables, keeping the separation distance from other cables according to
Table 3.3 on page 23.
4. Grounding of the inverter according to instruction of the
on page 20.
5. Grounded power supply.
