6.1 Safety
WARNING
Personal injury due to incorrect supply voltage.
An incorrect supply voltage may result in personal injury.
■
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.
6.2 Wiring notes
NOTE

NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
To ensure trouble-free operation, observe the following wiring instructions:
•
Connect the connecting cables in a de-energized state. Switch on the supply volt‐
age only after complete installation/connection of all connecting cables to the
device and control system.
•
Grounding of the housing is not required.
•
A twisted-pair cable is necessary for connecting the RS-422 serial interface or SSI.
•
The wires of unused switching outputs must be insulated at the control cabinet.
•
For the supply cable, a minimum cross-section of 0.25 mm² is recommended. This
results in a maximum length of the connecting cable up to the feed-in point of
30 m, at operation at 24 V and for the maximum switching current of 100 mA per
switching output.
•
Use proper connecting cables and male connectors for the application/environ‐
ment, see "Accessories", page 108.
•
The specified enclosure rating of the distance sensor is valid only with suitable
mating connectors or with the protective caps installed.
•
Electrical protection class III/SELV or PELV supply voltage.
•
Use shielded cables. Position screen on both sides and connect to earth on the
control side with a large surface area. Appropriate measures must be taken to pre‐
vent equipotential bonding currents flowing through the cable shield.
