2.4 Cubicle’s erection
.
!
CAUTION! The encapsulating sheet steel of cubicles may have sharp edges inside and on the roof.
Before erection the highest point of the floor is identified. The erection begins with the left hand cubicle
which is placed in level with the highest point. The cubicles are trestled if necessary in the front, at the back
and the middle along the switchgear. This is made by one or more layers of thin steel plates.
If the cubicle will be mounted against the wall make sure that the bolts for the rear cover are tightened
before fixing the cubicles.
See also 2.5 before the next cubicle is installed. Next cubicle can then be installed and aligned and adjusted
to the first one.
Tighten the cubicles with bolts in the fitting holes close to the front and rear sides. The fixing is made by
M8X25 bolts.
Remaining cubicles should be erected in the same way. When all cubicles are erected the alignment of the
fronts should be checked.
