Appendix 4 Emc And Low Voltage Directives; Measures To Comply With The Emc Directive - Mitsubishi Electric AnyWire NZ2AW1C2AL User Manual

Appendix 4
Compliance with the EMC Directive, which is one of the EU directives, has been mandatory for the products sold within EU
member states since 1996 as well as compliance with the Low Voltage Directive since 1997.
To prove the compliance, manufactures must issue an EC Declaration of Conformity and the products must bear a CE
marking.
Sales representative in EU member states
The authorized representative in EU member states will be:
Company name: MITSUBISHI ELECTRIC EUROPE B.V.

Measures to comply with the EMC Directive

The EMC Directive sets two requirements for compliance: emission (conducted and radiated electromagnetic energy emitted
by a product) and immunity (the ability of a product to not be influenced by externally generated electromagnetic energy).
This section summarizes the precautions for machinery constructed with this product to comply with the EMC Directive.
These precautions are based on the requirements of the EMC Directive and the harmonized standards. However, they do not
guarantee that the entire machinery constructed according to the descriptions complies with the EMC Directive.
The manufacturer of the machinery must determine the testing method for compliance and declare conformity to the EMC
Directive.
Installation in a control panel
This open-type device is intended to be placed in an industrial control panel or similar type of enclosure.
This ensures safety as well as effective shielding of programmable controller-emitted electromagnetic noise.
*1 Modules on the remote station in each network must be also installed inside the control panel. However, the waterproof type remote
station can be installed outside the control panel.
■Control panel
• Use a conductive control panel.
• Mask off the area used for grounding when securing the top or bottom plate to the control panel using bolts.
• To ensure electrical contact between the inner plate and the control panel, mask off the bolt installation areas of an inner
plate so that conductivity can be ensured in the largest possible area.
• Ground the control panel with a thick ground cable so that low impedance can be ensured even at high frequencies.
• Keep the diameter of the holes on the control panel to 10cm or less. If the diameter is larger than 10cm, electromagnetic
wave may be emitted. In addition, because electromagnetic wave leaks through a clearance between the control panel and
its door, reduce the clearance as much as possible. Use of EMI gaskets (sealing the clearance) can suppress undesired
radiated emissions. The tests by Mitsubishi were conducted using a control panel having the damping characteristics of
37dB (maximum) and 30dB (average) (measured at 3m distance, 30 to 300MHz).
■Installing ground wiring
Run the cable of this product as instructed below
• Provide a ground point to the control panel near the product. Ground the LG terminal of the product to the ground point with
the thickest and shortest ground cable possible (30cm or shorter).
