6 Installation of PIOX R400, R400B, R400C, R400A2
6.4 Connection of Sensor PIOX R400 with Transmitter PIOX TR379
Mount the sensor to the pipe at the selected measuring point (see chapter 5). The cable glands for connecting to
the junction box and transmitter are included with the PIOX R400.
6.4.1 Direct Connection
•
Prepare the sensor cable (see Fig. 6.9) and connect the leads to the terminals of the transmitter
(see Tab. 6.1).
6.4.2 Connection via Junction Box
•
If using a junction box, connect the cable leads of the extension cable to the terminals of the transmitter (see
Tab. 6.1).
•
Connect the cable leads of the extension cable and of the senor cable to the terminals of the junction box (see
Fig. 6.10).
6.5 Connection of Sensor PIOX R400B, R400C, R400A2 with Transmitter PIOX
TR374B, TR374C, TR374A2
Mount the sensor to the pipe at the selected measuring point (see chapter 5). The cable glands for connecting to
the junction box and transmitter are included with the PIOX R400.
6.5.1 Direct Connection
•
Remove the blind plug for the connection of the sensor (see Fig. 6.12).
•
Open the cable gland of the sensor cable. The compression part remains in the cap nut (see Fig. 6.11).
•
Push the sensor cable through the cap nut and the compression part.
Note!
It is recommended to run the cables from the measuring point to the transmitter before the
connection of the sensor, to avoid load on the connectors.
Note!
The terminals for connecting the sensor to the transmitter PIOX TR379 are located on termi-
nal strip KL6.

Attention!
The degree of protection IP 65 of the transmitter is only guaranteed if the cables fit firmly and
tightly in the cable glands, the cable glands are firmly tightened and the housing has been
tightly screwed.
Note!
It is recommended to run the cables from the measuring point to the transmitter before the
connection of the sensor, to avoid load on the connectors.
Attention!
Always observe the "Safety Instructions according to Directive 94/9/EC" (see document
SIPIOX_R400).
