Installation and Connection
4. Relays, contactors, solenoids or coils of electromechanical brakes installed close to the
inverter may eventually create interferences in the control circuitry. To eliminate this effect,
RC suppressors (with AC power supply) or free-wheel diodes (with DC power supply) shall
be connected in parallel to the coils of these devices.

3.2.6 Cable Distances

The power cables and control cables must be separated (relay output cables and other control
cables) according to Table 3.2 on page

3.3 INSTALLATION ACCORDING TO THE EUROPEAN DIRECTIVE OF
ELECTROMAGNETIC COMPATIBILITY
All inverters have internal C3 RFI filter to reduce electromagnetic interference. These inverters,
when properly installed, meet the requirements of "EMC Directive 2004/108/EC".
The CFW701 inverter series was developed for professional applications, applying the harmonic
emission limits defined by standards EN 61000-3-2 and EN 61000-3-12. The inverters meet the
EN 61000-3-2 requirements without restrictions and EN 61000-3-12 when installed in networks
with a drop lower than 1%.

3.3.1 Conformal Installation

1. Inverters with built-in C3 RFI filter CFW701...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
142 .
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 17 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 18.
