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 "EMC Directive
89/336/EEC" with the 93/68/EEC supplement.
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
208.
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
3.4 on page 18 and keep the proper separation from other cables according to
Cable Distances on page
radiated emission levels are presented at
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.
