Except for the
height, B68-18 (1.8m in height) cabinet and B68-22 (2.2m in height) cabinet
have the same installation requirements in space planning, cabinet positioning,
and fixing.
Therefore, the B68
cabinet installation flow will be described only taking the B68-22 cabinet as
an example.
1)
The site should be correctly marked off prior to
the installation. .
2)
The cabinet must be handled with care to prevent
damage to any components.
3)
After the installation, make the all-around
check on the cabinet so as to find the defects and make the timely handling.
Clean the stains resulting from the installation.
According to different floors in the
equipment room, the B68-22 cabinet can be installed on the cement ground or on
the raised floor. The brief installation procedure includes:
1)
Cabinet foot installation (If the installation
is on the raised floor, the support and slide rail should be installed)
2)
Cabinet Installation
3)
Quakeproof reinforcement
The B68-22 cabinet is installed on the
cement ground with the anchor plates pressing against the cabinet feet, and the
anchor plate kit is used for the B68-22 cabinet. The cabinet feet are
height-adjustable.
The feet are
insulated. The anchor plate components include insulating units. During
construction, make sure that the insulating units are correctly installed so
that the whole set of equipment is insulated from the ground before the ground
wire is connected, thus effectively meeting the insulation requirement.
The anchor plate of the B68-22 cabinet is

I. Planning the installation
position of cabinet
Before the
installation, first plan the available space. There should be sufficient space
for maintenance and operation at the front and rear doors of the cabinet, as
shown in Figure B-4 and Figure B-5. At least 800mm clearance is required around the B68-22 cabinet.
II. Drawing lines
According to the
reference dimension and cabinet foot location dimension in the construction
plane design diagram, determine the location of the cabinet installation hole,
measure several marking-out points, mark out two lines which are parallel with
the reference and whose spacing is 720mm. According to the design requirements,
determine the installation hole location and cabinet foot location used for the
first cabinet on the two lines. Then take the hole as the reference point, and
mark out the installation holes and cabinet foot location marks used for other
cabinets one by one. To avoid faults, after being marked out, all hole location
lines should be measured again so as to ensure the proper dimension. Figure B-4 shows the installation holes and cabinet foot location marks of a
single cabinet, and Figure B-5 shows the installation holes and cabinet foot location marks of two

III. Drilling holes
Use a percussion drill with 16 bit to drill
holes for the installation of the expansion bolts to fix the anchor plate.
When using the percussion drill, be sure to
hold the bit perpendicular to the ground. Hold the drill handle firmly with
both hands to control the direction. Do not shake the drill to avoid tilted
holes or prevent damage to the floor.
The depth of the hole should be within the
range of 52mm~60mm, and the depth of all holes should be the same. Clean the
hole before measuring the net-depth. When a hole is drilled, use a vacuum
cleaner to clean the dust.
If it is difficult to position the drill
bit when the ground is too hard or slippery, chisel a pit at the hole-mark to
help position the bit.
Marking and drilling are the fundamental
work for hardware installation. Any poor precision may cause great
inconvenience for the follow-up jobs.
Caution:
Keep the depth of
the hole between 52mm and 60mm. Otherwise, the expansion bolt cannot be
installed and fastened properly.
IV. Installing expansion bolts
Prior to installation, clean the dust
inside and outside the hole with vacuum cleaner and then measure the spacing
between holes. Relocate and drill before installing expansion bolt in case of
poor accuracy.
Take down the expansion tube and expansion
nut, put them into the hole vertically (the guide rib on the expansion nut has
to be inserted into the guide trough of the expansion tube in advance), and
then punch the expansion tube with rubber mallet until the expansion tube is
completely driven into the ground. Figure B-6 shows the installation of expansion tube and expansion nut.
