Electrical connection
6.1
Overview
The assignment of the electrical connections is dependent on the type of sensor that is used. The type des-
ignation of the sensor is specified on the name plate.
CAUTION
Safety notices!
Ä
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the name plate.
Ä
Only allow competent persons to perform the electrical connection.
Ä
Ensure that the functional earth (FE) is connected correctly.
Fault-free operation is only guaranteed if the functional earth is connected properly.
Ä
If faults cannot be rectified, take the sensor out of operation. Protect the sensor from acci-
dentally being started.
NOTICE
Protective Extra Low Voltage (PELV)
Ä
The sensor is designed in accordance with protection class III for supply with PELV (protec-
tive extra-low voltage with reliable disconnection).
NOTICE
Ä
For all connections (connection cable, interconnection cable, etc.), use only the cables listed
in the accessories (see chapter 13.2 "Accessories – cables and connectors").
Ä
Use shielded cables when using the analog interface. You can thereby prevent interference
caused by electromagnetic fields.
