4.3 Outputs
The terminal assignment is described in the standard manual.
For more information refer to chapter "Electrical data".
The 4...20 mA current output circuit and the pulse output circuit are galvanically isolated from
each other.
Both, the 4...20 mA current output and the pulse output terminal are galvanically isolated from
earth ground (test voltage 500 VAC or 707 VDC between te, - and earth ground terminal).
4.4 Grounding
Equipotential bonding
Vortex flowmeter must be connected to the equipotential bonding system of the hazardous area
either to the internal or external ground terminal.
The access to the terminals and the connection of the terminals is explained in detail in the
standard manual.

INFORMATION!
In the case of compact flowmeters and flow sensors with flange connections, the flow sensor
may be electrically conductive connected to the piping.
