When connecting Ex-certified devices, please refer to the notes and diagrams in the Ex-specific
supplement to these Operating Instructions.
Please do not hesitate to contact your Hauser representative if you have any questions.
4.1 Connecting the remote version
4.1.1 Connecting the sensor
!
Note!
• The remote version must be grounded. In doing so, the sensor and transmitter must be connected
to the same potential matching.
• When using the remote version, always make sure that you connect the sensor only to the
transmitter with the same serial number. Compatibility errors (e.g. the incorrect K-factor will be
used) can occur if the devices are not connected in this way.
1. Remove the cover of the connection compartment of the transmitter (a).
2. Remove the cover of the connection compartment of the sensor (b).
3. Feed the connecting cable (c) through the appropriate cable entries.
4. Wire the connecting cable between the sensor and transmitter in accordance with the
electrical connection diagram:

5. Tighten the glands of the cable entries on the sensor housing and transmitter housing.
6. Screw the cover of the connection compartment (a/b) back onto the sensor housing or
transmitter housing.
