4.3.3 Rail-mount transmitter (Non-Ex)
DANGER!
Neither operate this transmitter in potentially explosive areas, nor connect it to a sensor located
in a potentially explosive area! Otherwise the transmitter might cause an explosion that can
result in fatal injuries!
CAUTION!
Note that the maximum output load always depends on the power supply. If the maximum output
load is exceeded, then the measured value will become incorrect. For further information refer
to the output load diagrams in the chapter "Technical data".
INFORMATION!
The transmitter has a polarity protection. Connecting the power supply with a wrong polarity will
not damage the transmitter.
