6.1.2 Environmental installation conditions
Provide a protective roof or wall if the explosion-protected device is exposed to weather.
Equip explosion-protected electric equipment with a breather and drain valve in order
to prevent the vacuum effect. Observe the correct mounting orientation (bottom) when
doing so. See also section 6.1.1
Do not create any cold bridges (risk of condensation). If necessary, mount the enclosure
with a clearance to reduce condensation in the enclosure to a minimum.

• Alignment of enclosure depending
on mounting type:
• For vertical mounting:
any alignment
• For horizontal mounting:
cover on top

Operation under difficult conditions, such as on ships or in strong sunlight, requires
additional measures to be taken for correct installation, depending on the place of use.
Further information and instructions on this can be obtained from your regional sales
contact on request.
DANGER! Explosion due to severe heat-up inside the enclosure!
Non-compliance results in fatal or severe injuries.
Ensure that distances between Ex e electric circuits and Ex i electric circuits comply
with standards (EN IEC 60079-11).
Select suitable conductors that do not exceed the permitted heating temperature
within the enclosure.
Pay attention to the specified cross-sections.
Attach the core end sleeves properly.
DANGER! Explosion due to improper installation!
