ELECTRICAL CONNECTIONS
GROUNDING INSTRUCTIONS
ALWAYS ensure that the Converter and the Sensor are grounded (earthed) correctly.
The grounding of t he sensor and converter ensures th at the equipment and liquid are
equipotential.
CONVERTER POWER SUPPLY
L
(-)
N
(+)
Before connecting the power supply, verify that the
mains voltage falls between the limits indicated on
the tag plate.
ATTENTION: Converters on a dc power supply line
are not protected against the inversions of p o larity.
When wiring the converter and sensor equipme nt use
only approved conductors, with fire- proof p r op erties.
The power supply line must be equipped with an
external protection for current overload (fuse or
automatic line breaker, limiting current to less than
10 A).
Provide in close proximity to the converter a circuit
breaker that must be easily accessible to the operator
and clearly identified.
NOTE: For characteristics of the converter’s power
supply, see page 4
The sensor, hardwired inputs and outputs are connected to the converter
through a terminal block locate inside the converter.
To locate the terminal block loosen the 4 screws on the front cover. Lift the
front panel. With the front cover lifted, the terminal block is visible. The
terminal block is the hardwire connection of the converter to external
equipment, including the sensor.
The following pages give information on the terminal block numbering, and the
respective connecting of the senor cables, and input/outputs.
