9.1.1 Standards relevant to the EMC Directive
(1) Emission related standards
* 1 : QP: Quasi-Peak value, Mean: Average value
* 2 : Programmable controller is an open type device (a device designed to be housed in other
equipment) and must be installed inside a conductive control panel. The tests were conducted
with the programmable controller installed in a control panel, applying the maximum applicable
input voltage to the power supply module.
(2) Immunity related standards
* 1 : Programmable controller is an open type device (a device designed to be housed in other
equipment) and must be installed inside a conductive control panel. The tests were conducted
with the programmable controller installed in a control panel, applying the maximum applicable
input voltage to the power supply module.
* 2 : The accuracy of an analog-digital converter module may temporarily vary within ±10%.
