6 Installation of FLUXUS G704
6.4 Connection of the Transducers - Connection System TS
It is recommended to run the cables from the measuring point to the flowmeter before the
connection of the transducers to avoid load on the connection points.
Overview
6.4.1 Transducers (ATEX Zone 1) - Direct Connection
Observe the safety instructions in chapter 2.
• Remove the left blind plug for the connection of the transducers (see Fig. 6.3).
• Open the cable gland of the transducer cable. The compression part remains in the
cap nut.
• Push both transducer cables through cap nut and compression part.
• Prepare the transducer cables with the cable gland. Cut the outer shield and brush it
back.
• Tighten the gasket ring side of the basic part in the housing.
• Insert the transducer cable in the housing.
• Fix the cable gland by screwing the cap nut on the basic part.
• Connect the leads to the terminals of the flowmeter (see Fig. 6.3 and Table 6.1).
Note!
If transducers are replaced or added, the sensor module has to be
replaced or added, too (see section 6.10).

Attention!
For good high frequency shielding it is important to assure good con-
tact between the cable shield and the cap nut (and thus the housing).
