Instructions For Compliance With The European Standards - Mitsubishi Electric FR-A520-0.4K-NA Instruction Manual

2.3.8 Instructions for compliance with the European standards

(The products conforming to the Low Voltage Directive carry the CE mark.)
( 1 ) EMC Directive
1) Our view of transistorized inverters for the EMC Directive
A transistorized inverter does not function independently. It is a component designed for installation in
a control box and for use with the other equipment to control the equipment/device. Therefore, we
understand that the EMC Directive does not apply directly to transistorized inverters. For this reason,
we do not place the CE mark on the transistorized inverters themselves. (The CE mark is placed on
inverters in accordance with the Low Voltage Directive.) The European power drive manufacturers'
organization (CEMEP) also holds this point of view.
2) Compliance
We understand that the transistorized inverters themselves are not covered directly by the EMC
Directive. However, the EMC Directive applies to machines/equipment into which transistorized
inverters have been incorporated, and these machines and equipment must carry the CE marks.
Hence, we prepared the technical information "EMC Installation Guidelines" (information number BCN-
A21041-202) so that machines and equipment incorporating transistorized inverters may conform to
the EMC Directive more easily.
3) Outline of installation method
Install an inverter using the following methods:
* Use the inverter with an European Standard-compliant noise filter.
* For wiring between the inverter and motor, use shielded cables or run them in a metal piping and
ground the cables on the inverter and motor sides with the shortest possible distance.
* Insert a line noise filter and ferrite core into the power and control lines as required.
Full information including the European Standard-compliant noise filter specifications are written in
the technical information "EMC Installation Guidelines" (information number BCN-A21041-202).
Please contact your sales representative.
( 2 ) Low Voltage Directive
1) Our view of transistorized inverters for the Low Voltage Directive
Transistorized inverters are covered by the Low Voltage Directive.
2) Compliance
We have self-confirmed our inverters as products compliant to the Low Voltage Directive and place
the CE mark on the inverters.
3) Outline of instructions
* In the 400V class inverters, the rated input voltage range is three-phase, 380V to 415V, 50Hz/60Hz.
* Connect the equipment to the earth securely. Do not use an earth leakage circuit breaker as an
electric shock protector without connecting the equipment to the earth.
* Wire the earth terminal independently. (Do not connect two or more cables to one terminal.)
* On the input side, use the recommended no-fuse breaker and magnetic contactor which conform to
the EN or IEC Standard.
* Use the inverter under the conditions of overvoltage category II and contamination level 2 or less set
forth in IEC664.
(a) To meet the overvoltage category II, insert an EN or IEC standard-compliant isolation transformer
or surge suppressor in the input of the inverter.
(b) To meet the contamination level 2, install the inverter in a control box protected against ingress of
water, oil, carbon, dust, etc. (IP54 or higher).
* In the input and output of the inverter, use cables of the type and size set forth in EN60204 Appendix
C.
* The operating capacity of the relay outputs (terminal symbols A, B, C) should be 30VDC, 0.3A. (The
relay outputs are basically isolated from the inverter's internal circuitry.)
Details are given in the technical information "Low Voltage Directive Conformance Guide" (information
number BCN-A21041-203). Please contact your sales representative.
