ATEX:
The sensor circuit is not infallibly galvanic isolated from the Fieldbus input circuit.
However, the galvanic isolation between the circuits is capable of withstanding a test
voltage of 500Vac during 1 minute.
For Zone 2 installation EEx nA IIC without barrier, provisions must be made to the
supply to prevent transients from exceeding 40% of Vmax.
Production year of 6350 can be taken from the first 2 digits of the serialnumber.
There are no user serviceable parts inside the transmitter
