Endress+Hauser Liquisys M CLM253 - Field Device Connection; Panel-mounted Device Connection

Electrical connection Liquisys M CLM223/253
20 Endress+Hauser
Please note the following:
• The device is approved for protection class II and is generally operated without a
protective ground connection.
• To guarantee measuring stability and functional safety, you must connect the outer
shield of the sensor cable:
– Inductive sensors: terminal "S"
– Conductive sensors: PE distributor rail
This is on the cover frame in the case of panel-mounted devices, and in the connection
compartment in the case of field devices. Ground this PE distributor rail or the ground
terminal directly on site wherever possible.
• Circuits "E" and "H" are not galvanically isolated from each other.
Field device connection
Guide the measuring cables through the PG glands into the housing. Connect the
measuring cables in accordance with the terminal assignment.
