Wiring with M12 connector
Before connection please note the following:
"
PROFIBUS devices are marked on the nameplate (1). The
voltage is determined by the PROFIBUS standard and the
Caution! desired safety concept. (see chapter 4.3).
Connect potential matching line to transmitter earth terminal
before connecting up the device.
Tighten the locking screw:
It forms the connection between the probe and the housing
earth potential.
When you use the measuring system in hazardous areas, make sure you comply with
national standards and the specifications in the safety instructions (XA's).
Make sure you use the specific cable gland.
-
On devices supplied with a certificate, the explosion protection
is designed as follows:
Housing F12 - EEx ia:
Power supply must be intrinsically safe.
The electronics and the current output are galvanically
separated from the antenna circuit.
The Levelflex M is connected as follows:
Insert plug (2) into bushing (3).
Screw firmly
Ground the device according to the desired safety concept.
