Chapter 10 EMC Standard
10.1 The requirements for compliance with EMC standards
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 XGT PLC 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
