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.
Observe the following notes to ensure safe and trouble-free operation:
•
Connect the connecting cables in a de-energized state. Do not switch on the
supply voltage until installation is complete and all connecting cables have been
connected to the device and control.
•
Wire cross-sections in the supply cable from the customer’s power system should
be designed in accordance with the applicable standards. Protect the device with
an external slow-blow fuse of 5 A at the beginning of the supply cable, viewed from
the voltage supply.
•
The specified enclosure rating of the device when mounted is reached only if
suitable mating connectors or protective caps are used.
•
Do not open the screwed housing of the device, since the warranty will then
become void.
•
Turn the rotatable electrical connections max 270° from end position to end
position.
•
Prior to connecting the I/O line, check the device configuration for the inputs/
outputs.
•
Avoid tensile loads to the connecting cables.
•
Maximum cable lengths for the voltage supply depending on the power supply
voltage used (conditions: cable cross-section 0.34 mm², 20 °C cable tempera‐
ture, 10 V applied to the device, max. power consumption as per type label):
5.5 m at 12 V; 40 m at 24 V; 57 m at 30 V.
