NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
The enclosure rating stated in the technical data is achieved only with screwed plug
connectors or protective caps.
All circuits connected to the device must be configured as SELV or PELV circuits. SELV =
safety extra-low voltage, PELV = protective extra-low voltage.
Connect the connecting cables in a de-energized state. Do not switch on the supply volt‐
age until installation is complete and all connection work on the device and controller
has been finished.
Wire cross-sections in the supply cable from the customer’s power system must be
implemented in accordance with the applicable standards.
Take suitable external safety measures to protect the switching inputs, switching out‐
puts and their supply voltage against transient overvoltage.
Only use cables with shielding on both sides for wiring.
