1 For your safety

1.1 Appropriate use

P

lug connectors belong to the accessories for level, switching
and pressure sensors. They provide a detachable connection
to power supply/signal processing for two-wire sensors. Those
are sensors whose power supply as well as measurement
signal are transmitted over one pair of wires.

1.2 Impermissible use

As a rule, plug connectors are not allowed to be used with four­wire instruments. Those are sensors whose power supply and
measurement signal are transmitted over two separate pairs of
wires.

1.3 General safety instructions

The safety information in the operating instructions manual of
the respective sensor must be noted.

1.4 Safety instructions for Ex areas

Please note the Ex-specific safety information for installation
and operation in Ex areas. These safety instructions are part of
the operating instructions manual and come with the Ex­approved instruments.

For instruments with Exd or StEx approval, the use of plug
connectors is not allowed.
