Requirements For Compliance With The Emc Directive - Mitsubishi ME96SSR-MB User Manual

EMC Directive Instruction
This section summarizes the precautions on conformance to the EMC Directive of the cabinet constructed
using this instrument.
However, the method of conformance to the EMC Directive and the judgment on whether or not the cabinet
conforms to the EMC Directive has to be determined finally by the manufacturer.
This instrument complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This instrument may not cause harmful interference, and (2) this instrument must accept any interference
received, including interference that may cause undesired operation.
1．EMC Standards
 EN 61326-1
 EN 61000-3-2
 EN 61000-3-3
2．Installation (EMC directive)
The instrument is to be mounted on panel of a cabinet.
Therefore, the construction of a cabinet is important not only for safety but also for EMC.
The instrument is examined by the following conditions.
 Conductive cabinet is used.
 Six faces of a cabinet have to be ensured conductivity for each other.
 A cabinet has to be connected to earth by a thick wire of low impedance.
 Holes on faces of cabinet have to be 10 cm or less in diameter.
 The terminals for protective earth and functional earth have to be connected to earth by a thick wire of
low impedance. (A terminal for protective earth is important not only for safety but also for EMC.)
 All connections must be kept inside the cabinet.
 Wirings outside the cabinet have to be used with the shielded cable.
The following diagram shows how to provide good contact of the shielded cable.
・Remove part of the outer cover.
・Remove part of the paint musk on the cabinet.
・Connect those parts with the clamp.
