WIRING
Under the cover

you will find the terminal board.
The figure above shows the wiring connection of the transmitter. The 2-wires must be connected to +
and - on the terminal board. The wiring terminals can be operated without a screwdriver. The
opening levers of the terminals can be lifted and pressed down by hand. Lift the opening levers of the
terminals and insert the corresponding wires. Press down the levers by hand, the terminal spring will
close and the wire is clamped.
The transmitter must be connected with standard two-wire shielded cable. Do not run signal wiring
in open trays with power wiring, or near heavy electrical equipment (e.g. Frequency controllers or
heavy pumps). Shielding must always be connected at the side of the power supply. In case the
process connection is already connected to ground (e.g. via the tank or pipe line) do
not
connect the
instrument to ground. In applications with synthetic process connections, the enclosure (internal or
external) must be connected to ground.
For proper function, please make sure that the polarity is correct. Although the transmitter is
equipped with reverse polarity protection, it only functions if the connection is correct.
Please ensure that the transmitter is not connected to ground twice to prevent an earth loop.
Insert the wires into the connector and
push the lever down by hand.
