Alignment of enclosure depending on mounting type:
• For vertical mounting: any alignment
• For horizontal mounting: cover on top
• Hanging position/overhanging cover is not permitted!
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.
DANGER! Explosion due to incorrect mounting position!
Non-compliance results in fatal or severe injuries.
Mount the device only on the floor or wall, not overhead or in a free-standing
position.
Mount the device torsion-free only on a level surface.
