Installations According To The European Electromagnetic Compatibility Directive; Conformal Installation; Definition Of The Standards - WEG CFW11W G2 Series User Manual

3.4 INSTALLATIONS ACCORDING TO THE EUROPEAN ELECTROMAGNETIC
COMPATIBILITY DIRECTIVE
The CFW-11W G2 inverters, when correctly installed, meet the requirements of the EMC Directive 2014/30/EU.
The CFW-11W G2 inverters were developed for professional applications only. Therefore, the limits for emission of
harmonic currents established by the IEC/EN 61000-3-2 and IEC/EN 61000-3-12 standards are not applicable.

3.4.1 Conformal Installation

For conformal installation, use:
Standard CFW-11W G2 inverter for emission levels according to IEC/EN61800-3 Adjustable Speed Electrical
„
Power Drive Systems, category C4.
Shielded output cables (motor cables) with the shield connected at both ends, motor and inverter, with low-
„
impedance connection for high frequency. Keep the separation from the other cables according to
on page 3-31.
Shielded control cables, keeping the separation distance from other cables according to
„
Connections on page 3-34.
Grounding of the inverter according to instructions of Items
„
and Item 3.2.12.2 UC11 G2 Connections on page

3.4.2 Definition of the Standards

IEC/EN 61800-3: "Adjustable Speed Electrical Power Drives Systems"
Environments:
First Environment: environments that include residential premises, as well as establishments directly connected
without intermediate transformers to the low voltage power line which supplies installations used for residential
purposes.
Example: houses, apartments, commercial installations or offices located in residential buildings.
Second Environment: environments that include all the buildings other than those directly connected to the low
voltage power line which supplies buildings used for domestic purposes.
Example: industrial areas, technical areas of any building supplied by a dedicated transformer.
Categories:
Category C1: inverters with voltage rating below 1000 V and intended for use in the First Environment.
Category C2: inverters with a voltage rating below 1000 V intended for use in the First Environment, not provided
with a plug connector or movable installations. They must be installed and commissioned by a professional.
Note: a professional is a person or organization familiar with the installation and/or commissioning of inverters,
including their EMC aspects.
Category C3: inverters with voltage ratings below 1000 V developed for application in the "Second Environment"
and not designed for application in the "First Environment".
Category C4: inverters with voltage rating equal or higher than 1000 V, or with a current rating equal to or greater
than 400 A, or intended for use in complex systems in the Second Environment.
