The mains voltage and power consumption are provided on the name plate for the transmitter.
The wire cross-section for the supply power must meet the requirements for the main fuse (VDE
0100). The power consumption is
≤
45 VA (flowmeter sensor, including transmitter).
The supply power is connected to terminal L (phase), N (neutral) or 1+, 2- and , as stated on
the name plate. The supply power connecting cable must be rated for the current consumption
of the flowmeter system. The cables must comply with IEC 227 or IEC 245. Connect a switch or
a line switch in the power supply line to the transmitter. This switch should be located near the
converter and marked as being associated with the device. The transmitter and the flowmeter
sensor have to be connected to functional ground in accordance with international standards.
Important
Please observe the limit values of the supply power (see "Technical Data"). Please note that
there is a voltage drop of the 24 V AC/DC supply power line if the cables are extremely long or
if the conductor cross section is extremely small.
The pin configuration must be as specified in the connection diagrams in chapter 5.4.
