Only connect the sensor when the
supply voltage is switched off.
Do not cut the sensor's connecting
cable. If you do, the measurement
results will be faulty.
Please note the relevant national
regulations during installation.
Only use appropriate cable end
sleeves.
Use a mains cable with a protec‐
tive conductor. The sensor cable
shield must be earthed via the pro‐
tective conductor if a disturbance
potential is present. To this end,
the plug and the socket must also
be appropriately configured.
