How to fasten DY800/216 cubicles
When the DY800/216 unit arrives, the base (1) is
fixed to the roof in an overturned position. Comply
with the following instructions to install the unit in a
raised substation:
– unbolt the base (1) from the roof. Lift it with a
crane using belts and, taking care to prevent the
upper bushings (2) from being damaged, place it
on the ground and turn it upside down
– make sure that the floor of the raised substation is
horizontal and well leveled with 2/1000 maximum
flatness (2 mm with respect to a square meter)
– place the base in the substation 20 mm from the
right-hand wall and 190 mm from the rear wall and
mark the positions of the holes;
– drill the floor, insert 4 expansion plugs and fix the
base in place. Make sure that the cable outlet (2) in
the base is on the left. It the unit must be
positioned in the left-hand corner of the
substation, turn the base through 180° and fix it at
the same distances with respect to the left-hand
wall:
– remove the unit from the pallet and take it into the
substation. Make sure that the upper bushings (3)
are not damaged when the unit passes through
the substation door and place it on top of the base
(see detail A). Fasten it with the screws removed
when the base was disassembled from the roof
– set the bracket (4) (see detail B) back on the roof,
on the right or left. Move it near to the wall and
mark the positions of the holes. Drill the wall,
insert 2 expansion plugs and fix the bracket
against the wall. Lock the bracket in place by
tightening the eyebolt and M16 screw
