.
The
switchgear
equipment
was
accurately
aligned
at
the
factory
.
This
care
insures
proper
operation
and
fit
of
mating
parts
.
Supporting
surfaces for
the
switchgear
at
each
anchoring
bolt locations
must
be level and
in
the
same
plane
within
0.06
"
(
1.6
mm
)
.
There
must not
be
any
projection
above this
plane
within
the
area
covered
by
the
switchgear
cubicles
.
If
purchaser
'
s
floor
or
grouted
sill channels do
not meet
this
requirement
,
it
will
be
necessary
to
shim
in
the
following
manner
.
The
six
(
6
)
anchor bolt
locations
in
each cubicle
must
freely
rest
in
firm
contact
with
the
mounting
support
surfaces
.
There
must not
be
any
projection
or
obstruction
in
other
areas
which
may
distort the cubicle
.
Do
not
force
cubicles
in
firm
contact
by drawing
down
anchoring
bolts because such drastic
means
will
distort
the cubicles
.
Add
4
"
(
100
mm
)
square
shims
adjacent
to
anchor
bolts
until
firm
contact
is achieved
.
Check
each
anchor bolt location
,
six
(

per
cubicle
.
(
See

.
Tighten
anchor bolts
or
weld
to
sills
.

.
If
the
lineup
consists
of
multiple
groups
,
move
the
next
group
into
position
,
with
the
front
of
units
in
line and
tight against
the
adjacent
group
.
Do
not
bolt
groups
together
at
this time
.
Check
that the cubicles
are
in
firm
contact
with
the
foundation
at
each
cor
-
ner
and anchor
point
,
and that bolt holes
are
in
align

ment
.
Add
4

)
square
shims
as
necessary
.
Tighten
the anchor
bolts
.
Now
,
bolt
groups
together
.

.
After
installation is
complete
,
the
lifting
bar
between
units
may
be removed and the
lift
bars
pushed
down
inside the units
.
Note
that bolts inside the units
which
clamp
the
lift
bars
in
place
must
be loose
to
allow
movement
of
the
lift
bar and
must
be
retight
-
ened
after
bar
has
been
lowered
.
