Warnings
Improper handling
The sensor connected to this device can be operated with high pressure and corrosive media.
Therefore improper handling of the device can lead to serious injuries and/or considerable
material damage.
● Only use cables with at least the same degree of protection as the sensor to install the
sensor.
It is recommended to use cables supplied by Siemens.
● Siemens supplied cables can be ordered with M12 plug on both ends or without plug.
● To guarantee the IP67 degree of protection, ensure that both ends of the cables are given
equivalent protection from ingress of moisture.
● For further information on Siemens-supplied cables, see Technical data (Page 41).
