5. Special conditions for save use

For pressurized enclosures that exceed the dimensions of 404mm length, 495mm width
and 181.5 mm in height, the maximum overpressure test in accordance with EN 60079-2,
16.1 has to be repeated with the respective enclosure.
The ambient temperature range differs from the standard temperature range and is
dependent on the structure and material of the gaskets, as well as the construction.
The different types are shown in the following tables:
Cabinet:
EPDM foamed
EPDM glued
Silicone punched
Silicone glued
Enclosure:
EPDM foamed
EPDM glued
Silicone punched
Silicone glued
For full certification as equipment the tests according to EN 60079-7:2007, 5.8, 6.8 and
Appendix E have to be performed or the maximum heating has to be calculated, if
necessary. Based on the results the appropriate temperature class has to be assigned.
Warnings in accordance with EN 60079-0:2009 and EN 60079-2:2007 as well as EN
60079-7:2007 and EN 60079-31:2009 corresponding to the application are required.
It must be ensured that the cabinets' tightness of IP66 or IP54 remains effective.
Accordingly, appropriate and approved components (e.g. cable entries and cable glands)
must be used.
It must be guaranteed that the explosion protection is not impaired or eliminated by the
number and size of the holes.
When using the viewing glass highly efficient charge generating mechanisms in the vicinity
of the enclosure have to be excluded.
