• In the event of potentially explosive vapor/air mixtures, only operate the device under atmospheric
conditions.
– Temperature: –20 to +60 °C
– Pressure: 80 to 110 kPa (0.8 to 1.1 bar)
– Air with normal oxygen content, usually 21 % (V/V)
• If no potentially explosive mixtures are present, or if additional protective measures have been
taken, the device may also be operated under non-atmospheric conditions in accordance with the
manufacturer' s specifications.
• Associated devices with galvanic isolation between the intrinsically safe and non-intrinsically safe
circuits are preferred.
• Only use the device in media to which the silicone rubber potting compound of the electronic
insert and the housing made of PBT, aluminum or 316L have sufficient durability.
• If there is a risk of dangerous potential differences within Zone 0 (e.g. through the occurrence of
atmospheric electricity), implement suitable measures for intrinsically safe circuits in Zone 0.
