8.1 General
Attention! Make sure that the voltage values of your system
correspond with the voltage values of the measuring unit.
• Make sure that the supply wires are de-energised.
• Connect the supply voltage and the output signal to the plug PIN's as stated
below.
• We recommend the use of wires with cross sectional area of min. 0.25 mm².
Attention! The measuring electrodes are galvanically connected
with the reference potential of the supply voltage and the signal
output.
8.1.1
If the device is installed in a continuously grounded / earthed metallic pipe, no
additional grounding / earthing of the housing is generally necessary. When
installing in a plastic pipe or any ungrounded pipe, the housing must be earthed
at the side threaded hole (M4) to ensure proper functionality of the MIM. A M4
screw (thread length max. 8 mm), a matching washer, a ring cable lug and a
toothed lock washer are required for correct installation.
These mechanical parts are not part of the delivery.
