NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
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 sup‐
ply voltage until installation is complete and all connecting cables have been con‐
nected 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. Use copper cables with
a cross-section of at least 0.25 mm
2
(approx. 24 AWG).
•
Protect the device with an external slow-blow fuse of 3 A at the beginning of the
supply cable, viewed from the voltage supply.
•
All electric circuits connected to the device must be designed as SELV or PELV cir‐
cuits (SELV = Safety Extra Low Voltage, PELV = Protective Extra Low Voltage).
•
The specified enclosure rating of the device when mounted is reached only if suit‐
able mating connectors or protective caps are used.
•
Do not open the screwed housing of the device, since the warranty will then
become void.
•
Prior to connecting the I/O line, check the device configuration for the inputs/
outputs.
•
Avoid tensile loads to the connecting cables.
