This controller has been designed and manufactured in conformity to Low Voltage
Directive 2006/95/EC , 2014/35/EU (LVD) and EMC Directive 2004/108/EC, 2014/30/
EU (EMC). For installation in industrial environments please observe following safety
guidelines:
• Separate control line from power wires.
• Avoid proximity of remote control switches, electromagnetic contactors, powerful
engines and use specific filters.
• Avoid proximity of power groups, especially those with phase control.
• It is strongly recommended to install adequate mains filter on power supply of
the machine where the controller is installed, particularly if supplied 230Vac. The
controller is designed and conceived to be incorporated into other machines,
therefore CE marking on the controller does not exempt the manufacturer of
machines from safety and conformity requirements applying to the machine itself.
