Safety
WARNING
Personal injury due to improper supply voltage!
■
Only operate the device using safety extra-low voltage and safe electrical insula‐
tion as per protection class III.
NOTICE
Equipment damage or unpredictable operation due to working with live parts.
Working with live parts may result in unpredictable operation.
■
Only carry out wiring work when the power is off.
■
Only connect and disconnect electrical connections when the power is off.

Wiring instructions
NOTE
Pre-assembled cables can be found online at:
•
NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
For data transmission, use only shielded cables with twisted-pair wires.
All electrical connections of the device are configured as M12 round connectors. The
connection male connectors of the device are compatible with SpeedCon™ quick con‐
nectors and standard M12 screw connectors.
The enclosure rating stated in the technical data is achieved only with screwed plug
connectors or protective caps.
Insulate the ends of unused wires of the connecting cables to avoid short-circuits.
Shielding requirements
■
To ensure a fault-free data transmission, an effective and comprehensive shielding
solution must be implemented.
■
Apply a cable shield at each end, i.e. in the control cabinet and at the device. The
cable shield of the pre-assembled cables is connected to the knurled nut and thus
also to a large area of the device housing.
■
The cable shield in the control cabinet must be connected over a large surface to
the ground potential on the potential equalization conductor.
■
Take appropriate measures to prevent equipotential bonding currents flowing
through the cable shield.
■
To ensure the highest possible EMC resistance, the alignment bracket must be
fastened so that it has a low-resistance electrical connection to the system.
■
During installation, pay attention to the different cable groups. The cables are
grouped into the following four groups according to their sensitivity to interference
or radiated emissions:
