Supply
The transmitter may only be connected to power supplies, instruments
or control devices that conform to the requirements of a grounded
extra-low voltage (SELV-E according to EN 61010). The connection to
the transmitter has to be fused
Voltage at the transmitter
Power consumption
1)
Fuse
The minimum voltage of the power supply unit must be increased proportionally to
the length of the sensor cable.
