The product is designed for a low degree of mechanical danger and
must be installed so that it cannot be mechanically damaged from
the outside.
ATEX device category
and peripheral de-
vices
The ATEX device category of the of the vacuum pump depends on
the connected components and the periphery. Components and pe-
ripheral devices must have the same or higher ATEX classification.
Preventing sources
of ignition
The use of ventilation valves is only permitted if it is ensured that
this normally does not produce explosive mixtures in the interior of
the of the vacuum pump or that in all probability explosive mixtures
are only briefly or rarely produced.
ð
If necessary, ventilate with inert gas.

The devices have a low mechanical protection and must be in-
stalled so that they cannot be mechanically damaged from the
outside; e.g., installing pumping units with impact protection,
attaching shatter protection for glass flasks, etc.
n
The devices are designed for an ambient and media tempera-
ture of +10 °C to ‒ +40 °C during operation. These ambient and
media temperatures must never be exceeded. When conveying/
measuring non-explosive gases, extended gas suction tempera-
tures apply, see chapter: Technical data, media temperature
(gas).
