Fasten the enclosure using the fastening tabs (see dimensional drawing for dimensions
of fastening holes). To do this, use two M8/M10 bolts to bolt the fastening tabs into the
threaded holes on the underside of the enclosure (see chapter "Technical data" for
tightening torque). Alternatively, fasten the enclosure by means of the threaded holes
directly on the reverse side.
Fit the hinges on side A or C (see figure) (see chapter "Technical data" for tightening
torque).

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. Observe the correct mounting orientation when doing so,
also see Chapter 6.1.1.
Do not create any cold bridges (condensation hazard). If necessary, install the enclosure
with a clearance to minimise condensation in the enclosure.
6.1.3 Final Preparation Steps before Use/Installation (for the 8250/0 Series)
Peel the film off the enclosure.
Clean the flat joint.
Apply Novasil S30 adhesive (SAP no. 230351) all around the groove.
Place the sealing ring into the groove and, if necessary, use a wooden spatula to press
it firmly into place.
Use spirit and a cloth to remove any excess adhesive.
