4.5 Flow sensor circuits (remote version only)

Observe the following points when connecting the flow sensor to the signal converter:
• Use only the supplied connecting cable (max. length 50 m / 164 ft).
• Before connecting or loosening the equipotential bonding cable, ensure there are no
differences in potential.
• Connect the connecting cable shield to the equipotential bonding of the hazardous area in the
wall bracket. On the flow sensor side, the shield must be carefully isolated from the earth
(test voltage 500 V
the terminal block.
• The terminal compartments of the flow sensor circuits are supplied with a bridge between
the internal PA connection and the terminal with the designation "gnye". This connection
must not be separated.
