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
NOTICE
Faults due to incorrect wiring.
Incorrect wiring may result in operational faults.
■
Follow the wiring notes precisely.
NOTE
Preassembled cables can be found online at:
b
The electrical connection of the device is configured as an M12 round connector. The
protection class stated in the technical data is achieved only with a screwed plug con‐
nector or cover cap.
Please observe the following wiring notes:
■
A correct and complete cable shielding design is required for trouble-free data
transmission.
■
The cable shield must be connected at both ends 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 to a large area of the
signal ground,
.
■
Appropriate measures must be taken to prevent equipotential bonding currents
flowing through the cable shield.
■
During installation, pay attention to the different cable groups. The cables are
grouped into the following 4 groups according to their sensitivity to interference or
radiated emissions.
°
Group 1: Cables very sensitive to interference, such as analog measuring
cables
°
Group 2: Cables sensitive to interference, such as device cables, communica‐
tion signals, bus signals
