,
it
should
be
turned
to
the
upright
position
and
placed
on
a
flat
surface
to
avoid
damage
to
breaker
parts
.
For
safety
,
all
handling
in
this
position
should
utilire

to
determine
if
any

is
evident
,
file
a
damage
claim
at
once

If
unpacking
is
delayed
,
difficulty
may
be
ex
-
perienced
in

.
Check
the
contents
of
each

before
discarding
any
packing
material
.
If
any
shortage
of
material
is

CLOSING
SPRING
OPERATION
The
two
closing
springs
supply
the
power
that
doses
the
circuit
breaker
and
also
charge
the
two
opening
springs
during
the
closing
operation
.
The
closing
springs
are
charged
by
a
motor
in
the
electrically
operated
breaker
and
charged
by
hand
in
the
manually
operated
breaker
;
however
,
in
either
type
,
the
springs
are
charged
the
same
amount
and
when
charged
,
the
spring
energy
is
available
to
close
the
breaker
,
thus
referred
to
as
"
stored
energy
.
”
The
closing
springs
are
normally
charged
when
the
breaker
is
opened
.
If
charged
after
closing
,
the
breaker
may
be
opened
and
then
reclosed
without
recharging
the
springs
.
In
drawout
breakers
,
the
closing
springs
are
automatically
dis
-
charged
when
the
breaker
is
moved
from
the
dis
-
connected
to
the
withdrawn
position
(
shown
in
Figure

.
This

Under
normal
operating
conditions
,
Ihe
closing
springs
are
automatically
charged
after
each
tripping
operation
.
However
,
there
are
occasions
when
the
springs
will
be
in
a
discharged
state
.
Therefore
,
it
is
desirable
that
means
be
available
to
indicate
the
charged
or
uncharged
condition
of
the
closing
springs
.
This
is
accomplished
by
a
visual

seen
through
an
aperture
in
the
escutcheon

.
The
indicator
is
marked
“
