EMC Directive Instruction

This section summarizes the precautions to have the cabinet constructed with the instrument conform to
the EMC Directive.
However, the method of conformance to the EMC Directive and the judgment on whether or not the
cabinet conforms to the EMC Directive must 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.
This equipment is class A as per EN 55011. This equipment is not intended for use in residential
environments and may not provide adequate protection to radio reception in such environments.
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 the panel of a cabinet.
Therefore, the installation to the cabinet is important not only for safety but also for conformance to EMC.
The instrument is examined in the following conditions.
 A conductive cabinet must be used.
 The conductivity of the six surfaces of the cabinet must be all ensured.
 The cabinet must be grounded by thick wires for low impedance.
 The hole drilling dimensions on the cabinet must be 10 cm or less in diameter.
 The terminals for protective earth and functional earth must be grounded by thick wires for low impedance.
The use of the terminal for protective earth is important not only for safety but also for conformance to
EMC.
 The connecting part of the terminal must be all placed inside the cabinet.
 Wiring outside the cabinet must be conducted with shielded cables, and the cables must be fixed to the
panel with clamps. (Strip the covering of shielded cable by a portion of clamp installation and then mask
the grounding part of the panel and clamp so as not to be painted.)
