NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
All electrical connections of the device are configured as M12 round connectors.
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
voltage until installation is complete and all connecting cables are connected to the
device and control.
Wire cross-sections in the supply cable from the customer’s power system must be
implemented in accordance with the applicable standards.
In the case of open end cables, make sure that bare wire ends do not touch. Wires
must be appropriately insulated from each other.
Wire cross-sections of the data and switching signal cables have to also be designed in
accordance with the applicable national standards.
Use shielded cables. Position the cable shield on both sides and connect to earth
on the control side with a large surface area. Take appropriate measures to prevent
equipotential bonding currents flowing through the cable shield.
