Assembly of clamping ring screw joints

ATTENTION!
In order to seal the system properly, proceed as follows:
Mount pipe connections without stress (using compensators if necessary).
Use piping with matching diameter and smooth surface.
Cut off the piping at right angles and deburr.
Slide coupling ring, support ring (if present) and clamping ring onto the
piping in that order.
Insert piping into joint as far as it will go.
Union firmly tighten.
Counter with a wrench on the screw-in side (do not load the device
housing) and tighten by 1 ¼ turns.

Electrical connections

ATTENTION!
The MFCs/MFMs are operated with 24 V power supply. Select the connector
cross-section according to the valve used and as large as possible (see Technical
Data ). Suitable connecting cables are to be found in Appendix A.
Connect the the functional earth (FE) to the marked screw, e.g. using round
pliers.
22 - MFC/MFM
With low flow rates and high pressures, pay attention to the
gastightness of the system to avoid false dosage or gas
leakage.
To assure electromagnetic compatibility (EMC), connect the
housing via as short a cable as possible (with as large a
cross-section as possible) to the functional earth (FE).
The GND or mass conductors of all signals of the MFC/MFM
must be led in each case individually to the MFC.
(If all GND signals are bridged directly at the MFC and only
one conductor led to the switching cabinet, signal
displacements and disturbances of the analog signals may
occur (pulses, oscillations, etc.)).
