Electrical connections

5.1

Information for connecting the power supply

IMPORTANT (NOTE)
— Observe the limit values for the power supply
listed in the "Technical data" section.
— Please remember that there is a voltage drop
associated with long lead lengths and small
lead cross-sections. The voltage at the
terminals of the device may not fall below the
minimum value required.
— Complete the electrical connection according
to the connection diagram.
The line voltage and power consumption are indicated on the
name plate for the transmitter.
A circuit breaker with a maximum rated current of 16 A must
be installed in the supply power line of the transmitter.
The wire cross-sectional area of the supply power cable and
the circuit breaker used must comply with VDE 0100 and must
be dimensioned in accordance with the current consumption
of the flowmeter measuring system. The leads must comply
with IEC 227 and/or IEC 245.
The circuit breaker should be located near the transmitter and
marked as being associated with the device.
The power supply is connected to terminal L (phase), N
(neutral), or 1+, 2-, and PE, as stated on the name plate.
Connect the transmitter and flowmeter sensor to functional
ground.
5.2

Information for cable installation

Make provision for a drip loop (water trap) when installing the
connecting cables for the flowmeter sensor.
If you are installing the flowmeter transmitter vertically, point
the cable entry points downwards. (You might need to rotate
the transmitter housing accordingly.)
