GROUNDING INSTRUCTIONS
ELECTRICAL CONNECTIONS
ALWAYS ensure that the transmitter and the sensor are grounded (earthed) correctly.
The grounding of the sensor and transmitter ensures that the equipment and liquid are
equipotential.
TRANSMITTER POWER SUPPLY
Before connecting the power supply, verify that the
mains voltage is within the limits indicated on name
plate.
ATTENTION: the converters on dc power supply line
are not protected against the inversions of polarity.
For the connections use only approved conductors, with
fire-proof properties, whose section varies from
0.25mm
2
to 2.50mm
2
, based on distance/power;
additionally fix the power supply wires with a additional
fastening system located close to the terminal.
The power supply line must be equipped with an
external protection for overload current (fuse or
automatic line breaker).
Provide close to the transmitter a circuit breaker easily
accessible for the operator and clearly identified; whose
symbols must conform to the electrical safety and local
electrical requirements.
Ensure that the component complies with the requirements of the standard for
electrical safety distance.
Check chemical compatibility of materials used in the connection security systems in
order to minimize electrochemical corrosion.
The sensor, hardwired inputs and outputs are connected to the transmitter through
a terminal blocks located inside the transmitter.
To locate terminal blocks loosen the 2 covers, front and rear. The terminal block
allows the hardwire connection of the transmitter to external equipment, including
the sensor.
The following pages give informations on the terminal block numbering, and the
respective connecting of the sensor cables, and inputs/outputs.
