5.5 Transmitter connection
5.5.1 Voltage supply connection
The connection voltage and current consumption are specified on the nameplate of the transmitter.
A circuit breaker with a maximum nominal current of 16 A must be installed in the voltage supply line of
the transmitter.
The conductor cross section of the voltage supply and the circuit breaker used must comply with
VDE 0100 and must be dimensioned in accordance with the current consumption of the flowmeter mea-
suring system. The lines must comply with IEC 227 and/or IEC 245.
The circuit breaker should be located near the transmitter and marked as belonging to the device.
The voltage supply is connected to terminal L (phase), N (neutral) or 1+, 2- and PE according to the
specifications on the nameplate.
The transmitter and sensor must be connected to the functional ground.
IMPORTANT (NOTE)!
There is the additional document "JUMO flowTRANS MAG S/H - Safety Manual Ex for devices 406012 -
406019" for the measuring systems that are used in potentially explosive areas.
The information and data contained in the document must also be strictly observed.
IMPORTANT (NOTE)!
The limit values of the voltage supply according to the specifications on the nameplate and in
chapter 13.4.1 "Electrical properties", page 198 must be observed.
The voltage drop for large cable lengths and small conductor cross sections must be observed. The volt-
age at the device terminals may not fall below the minimum value required according to the specifica-
tions on the nameplate and in chapter 13.4.1 "Electrical properties", page 198.
Establish the electrical connection according to the connection diagrams.
