EMC AND LOW VOLTAGE DIRECTIVES
9.1.1 Standards relevant to the EMC Directive
The standards relevant to the EMC Directive are listed in Table9.1.
*1: QP : Quasi-peak value, Mean : Average value
*2: Programmable controller is an open type device (a device designed to be housed inside other equipment) and must be
installed inside a conductive control panel.
The corresponding test has been conducted with the programmable controller installed inside a control panel.
Besides, our programmable controller has been tested with the maximum rated input value of the power supply module
to be used.
