▶
Fasten the enclosure using the fastening tabs (see dimensional drawing for dimensions of
mounting holes). To do this, use two M8/M10 screws to bolt the fastening tabs into the
threaded holes on the underside of the enclosure (see the "Technical data" chapter 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)
(for the tightening torque, see the "Technical data" chapter).

6.1.2 Environmental Installation Conditions
▶
A protective roof or wall can be provided if the explosion-protected device is exposed to
weathering.
▶
Equip explosion-protected electrical equipment with a breather and drain valve in order to
prevent the vacuum effect. Observe the correct mounting orientation when doing so;
see also 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 (item 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.
