General installation instructions
To avoid risk of ignition during installation and maintenance appropriate safety measures
against electrostatic discharge (ESD) are to be considered.
The sensor circuit is not infallibly galvanic isolated from the supply output circuit. However, the
galvanic isolation between the circuits is capable of withstanding a test voltage of 500Vac
during 1 minute.
For installation in a potentially explosive gas atmosphere the following instructions apply:
To avoid risk of ignition due to electrostatic discharge (ESD) the transmitter shall be mounted
in an enclosure providing a degree of protection of at least IP20 according to
EN/IEC 60529.
Ambient temperature range:
T4: -40 ≤ Ta ≤ 85ºC
T5: -40 ≤ Ta ≤ 60ºC
T6: -40 ≤ Ta ≤ 40ºC
For installation in a potentially explosive dust atmosphere, the following instructions apply:
The transmitter shall be mounted in a metal enclosure or equivalent that is providing a degree
of protection of at least IP6X according to EN/IEC 60529 that is suitable for the application and
correctly installed. Cable entries and blanking elements shall be used that are suitable for the
application and correctly installed. The surface temperature of the enclosure is equal to the
ambient temperature +20K for a dust layer with a maximum thickness of 5 mm.
Ambient temperature range:
T4: -40 ≤ Ta ≤ 85ºC
For installation in a potentially explosive atmosphere in mines, the following instructions apply:
The transmitter shall be mounted in an enclosure providing a degree of protection of at least
IP6X according to EN/IEC 60529. Cable entries and blanking elements shall be used that are
suitable for the application and correctly installed.
Ambient temperature range:
T4: -40 ≤ Ta ≤ 85ºC
