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 pins of the voltage supply are reverse polarity protected.
The protection class stated in the technical data is achieved only with screwed plug con‐
nectors or protective caps.
Observe the following notes to ensure safe and trouble-free operation:
•
When using shielded cables, place the cable shield in the control cabinet.
•
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.
•
The tightening torque for cables is typically 0.4 Nm or 0.6 Nm. This value must not
be exceeded.
•
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 6.3 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 and do not remove the laser pro‐
tection hood (if one has been fitted) as this will invalidate the warranty.
•
When configuring the digital inputs/outputs, make sure that the wired pins of two
devices are not functioning as an output concurrently (i.e., motor synchronization
with two devices configured as a master, or Out 1 concurrent with zero index signal
of an incremental encoder).
