Chapter 7 EMC Standard
The following explains contents, diagnosis and corrective actions for various errors that can occur during system operation.
7.1 Requirements for Conformance to EMC Directive
The EMC Directive specifies the products must “be so constructed that they do not cause excessive electromagnetic
interference (emissions) and are not unduly affected by electromagnetic interference (immunity)”. The applicable products
are requested to meet these requirements.
This section summarizes the precautions on conformance to the EMC Directive of the machinery assembled using PLC
XGB series. The details of these precautions are based on the requirements and the applicable standards control.
However, LSIS will not guarantee that the overall machinery manufactured according to the these details conforms to the
below-described directives. The method of conformance to the EMC directive and the judgment on whether or not the
machinery conforms to the EMC Directive must be determined finally by the manufacturer of the machinery.
7.1.1 EMC Standard
The standards applicable to the EMC Directive are listed below.
