EMC AND LOW VOLTAGE DIRECTIVES
*1: QP : Quasi-peak value, Mean : Average value
*2: The PLC is an open type device (device installed to another device) and must be installed in a conductive control panel.
The tests for the corresponding items were performed while the PLC was installed inside a control panel.
