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
.

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 the directive of electromagnetic compatibility
(2014/30/EU).
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

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
position (XE1). For more information see
