3.2.6 Cable Distances

The power cables and control cables must be separated (relay output cables and other control
cables) according to Table 3.3 on page

≥ 28 A
3.3 INSTALLATION ACCORDING TO THE EUROPEAN DIRECTIVE OF
ELECTROMAGNETIC COMPATIBILITY
The inverters with C3 option (CFW700...C3...) have internal C3 RFI filter to reduce electromagnetic
interference. These inverters, when properly installed, meet the requirements of the directive of
electromagnetic compatibility (2014/30/EU).
The CFW700 inverter series has been designed only for industrial applications. Therefore, the
emission limits of harmonic currents defined by the standards EN 61000-3-2 and EN 61000-3-2/A
14 are not applicable.

3.3.1 Conformal Installation

1. Inverters with built-in C3 RFI filter CFW700...C3...
2. Frame sizes A to D inverters with built-in C3 RFI filter capacitors grounding screws and frame
size E with J1 cable in the
214.
3. Shielded output cables (motor cables) and connect the shield at both ends (motor and
inverter) with a low impedance connection for high frequency. Use PCSx-01 kit supplied
with frame sizes A, B and C inverters. For frame sizes B and C with degree of protection
IP55, use the PCSC-03 shield kit. For frame sizes D and E inverters use the clamps supplied
with the product. Ensure good contact between the cable shield and the clamps. Refer to

and radiated emission levels are presented at
filter at the input of the inverter if necessary to have a lower emission level and/or a longer
motor cable length. For more information (RFI filter commercial reference, motor cable length
and emission levels) refer to
4. Shielded control cables and separate the remaining cables according to
Distances on page
5. Inverter grounding according to the instructions on
page 19.
6. Grounded power supply.
