6. UNCRATING
6.01 The cabinet is packed
and
shipped in a
normal
upright
position,
enclosed
in
a
polyethylene bag. A floating
arrangement,
consisting
of a polyfoam collar
at
the top and bottom of
the
cabinet, is used to secure the cabinet within
the
crate. The cabinet is secured to the shipping skid
by four bolts. The quick-connect block frames
are
secured in a lowered position for shipping. The
side panels
are
packed and shipped separately.
6.02 The shipping container measures 6 feet 3-1/8
inches in height,
has
a maximum width of
29-1/2 inches, and weighs approximately
135
pounds.
The
container
is
marked
with
the
J code
and
list
number
of the enclosed cabinet.
6.03 Place the cabinets as
near
as possible to
the
designated installation
area
and
uncrate
according to the procedure
attached
to the shipping
crate.
Immediately
destroy
the
polyethylene
bag
when
removed
from
the
cabinet.
Remove
the
four bolts securing the cabinet to
the
skid.
Caution:
The
top
is
not
fastened;
therefore,
care
should
be

when
positioning
the
cabinet.
7. INSTALLATION
7.01 Remove cabinet from skid and locate m
installation
area
as shown in Fig.

7.02
To
prevent damage in shipping, each slide
is secured in
the
cabinet with a slide stop
bolt assembly consisting of one P-160126 hex-head
cap screw, two P-284160
flat
washers, and one
P-154248 hex nut.
These
assemblies
must
be
removed
before
the
slides
can
be
withdrawn
from
the
cabinet.
Retain these
items for future use when
it
is necessary to relocate
or replace
the
cabinet. (See Fig.
5.)
7.03 Level the cabinet.
If
necessary, shim
the
base of
the
cabinet with small
strips
of
hardwood,
or
equivalent. A sufficient
number
of
Page

shims
should be used to equalize
the
weight
distribution along
the
base area.
7.04
Four
holes
are
located in
the
bottom of the
PBX cabinet for use when
it
is necessary
to fasten the cabinet to
the
floor. Secure
the
cabinet according to local instructions and job
requirements.
If
a rigid mounting is not required,
insert
P-40G472 plug buttons into the four holes.
Installation of
Equipment
7.05 When equipment
other
than
that
furnished
with
the
cabinet is required, mount the
additional equipment on slides
1,
2,
or 3 in positions
shown in Fig.
3.
Plug the equipment plugs into
the
slide connectors (Table
C),
as
required.
Optional
features
and
provision
for
lead
continuity
are
required
for
proper
system operation. See Section 551-728-210
for
method
of

7.06
Ensure
that
all plugs being used
are
secure
in
their
respective jacks.

a location where equipment noise will be a
problem, proceed as indicated in
paragraphs
7.08
through
7.10.
7.08 Soundproofing kits are available
on
an optional
basis for soundproofing
the
front
and end
panels of
the
cabinet. One
kit
is required for each
panel to be soundproofed. The kit consists of
two adhesive-backed polyurethane foam
tape
panels
24-1/2 inches long by 18-1/2 inches wide by
1/2
inch thick.
7.09
Install
the
soundproofing
