Mounting and Installation
6.1
Mounting / Dismounting
Mount the device carefully and only in accordance with the safety notes
(see Chapter "Safety").
Read through the following installation conditions and assembly instructions carefully and
follow them precisely.
6.1.1 Operating Position
The operating position is optional.
6.1.2 Environmental Installation Conditions
A protective roof or wall can be provided if the explosion-protected device will be exposed
to the elements outdoors.
Equip explosion-protected electric equipment with a breather and drain valve in order to
prevent the vacuum effect.
Do not create any cold bridges (condensation hazard). If necessary, install the enclosure
with a clearance to minimise condensation in the enclosure.
