The clearance between individual BKA-Üs must be at least
200 mm. The installation must be carried out in separate
installation openings. Fixing lugs (W=30 mm) may have to
be offset by at least 15 mm.
The minimum distance to adjacent components must be
(due to the construction) at least 110 mm (wall/ceiling). The
actual minimum distance may slightly differ from the dis-
tances mentioned therein and must be executed and
adapted as a function of the wall connection type.
Further information to be considered: see page 7 Minimum
distances or projecting ends.
The ER-A1 installation frame is to be ordered as an acces-
sory (extra charge)

supplied loose or factory-mounted.
