Special connection conditions

The output circuits are designed so 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 = 60 V.

Provided that rated voltage UM = 60 V is not exceeded if
connections are established to non-intrinsically-safe external
circuits, intrinsic safety is retained.
IMPORTANT (NOTE)
The transmitter and flowmeter sensor enclosures must be
connected to equipotential bonding PA. The operator must
ensure that when connecting the protective conductor PE no
potential differences can occur between the protective
conductor PE and the equipotential bonding PA.
