Special conditions
The output circuits are designed in such a way that they can be
connected to both intrinsically-safe and non-intrinsically-safe circuits.
It is not permitted to combine intrinsically safe and non-intrinsically
safe circuits. On intrinsically safe circuits, equipotential bonding must
be in place along the entire length of the cable used for the current
outputs. The rated voltage of the non-intrinsically safe circuits
is U M = 60 V.

Important
If the protective conductor (PE) is connected in the flowmeter's terminal box, you must ensure that no dangerous
potential difference can arise between the protective conductor (PE) and the equipotential bonding (PA) in the
potentially explosive area.

The contact output and the pulse output (terminals 41 / 42 and 51 /
52) can be wired internally as a NAMUR contact for the purpose of
connecting a NAMUR amplifier.
The cable glands are supplied in black by default. If the signal outputs
are wired to intrinsically safe circuits, we recommend that you use the
light blue caps supplied for the appropriate cable entries.
