Notes on the electrical installation
CAUTION
Danger due to incorrect supply voltage!
An incorrect supply voltage may result in injuries from electric shocks and/or damage to
the device.
■
Only operate the sensor with safety extra-low voltage (SELV).
NOTICE
Sensor 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.
■
The electrical installation must only be performed by electrically qualified person‐
nel.
■
Standard safety requirements must be met when working in electrical systems.
■
Only switch on the supply voltage for the device when the connection tasks have
been completed and the wiring has been thoroughly checked.
■
When using extension cables with open ends, ensure that bare wire ends do not
come into contact with each other (risk of short-circuit when supply voltage is
switched on!). Wires must be appropriately insulated from each other.
■
Wire cross-sections in the supply cable from the customer’s power system must be
designed in accordance with the applicable standards. When this is being done in
Germany, observe the following standards: DIN VDE 0100 (Part 430) and DIN VDE
0298 (Part 4) and/or DIN VDE 0891 (Part 1).
■
Circuits connected to the device must be designed as SELV circuits (SELV = Safety
Extra Low Voltage).
■
Protect the device with a separate fuse at the start of the supply circuit.
A shielded cable is not required in order to adhere to the electromagnetic compatibility
guidelines specified by EN 61000-6-2/4. It is recommended, however, especially when
working with longer connecting cables.
The IP enclosure rating for the sensor is only achieved if the connected cable is
completely screwed in.

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:
