ergy) must not connected in series. The
special installation regulations (DIN VDE
0165) must be observed.
Pressure transmitters in certain versions are
equipped with a warning label, informing of
measures to be taken to avoid electrostatic
discharge. Keep the contents of the warning
label in mind.
Connection cable
Make sure that the connection cable is speci-
fied for the expected operating temperatures
in your systems. The cable must have an
outer diameter of 5 … 9 mm. Otherwise the
seal effect of the cable connection will not be
ensured.
Cables for intrinsically safe circuits must be
marked with a blue colour and must not be
used for other circuits.
