Note: Information on EC Directives
Individual OMRON products that comply with EC Directives conform to the common emission standards of EMC Directives. How-
ever, the emission characteristics of these products installed on customers’ equipment may vary depending on the configuration,
wiring, layout, and other conditions of the control panel used. For this reason, customers are requested to check whether the emis-
sion characteristics of the entire machine or equipment comply with the EMC Directives.
