4. 2 Connecting the remote version
4.2.1 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 wiring diagram:  Fig. 15
 The wiring diagram in the connection compartment covers (a/b).
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.
