.
Receiving
Each
shipping
section
of
switchgear
has
been
palletized
to
facilitate
moving
.
The
shipping
section
is
covered
with
a
transparent
plastic
cloth
to
inhibit
entrance
of
foreign
particles
and
permit
carrier
awareness
of
shipping
contents
.
Immediately
upon
receipt
of
equipment
,
examine
components
making
note
of
any
damages
incurred
in
transit
.
If
necessary
,
immediately
file
a
claim
with
the
delivering
carrier
and
notify
your
Sylvania
representative
.
CAUTION
:
The
drewout
breaker
elements
are
secured
to
their
cradles
installed
in
the
switchgear
assembly
.
In
order
to
withdraw
the
element
,
it
is
first
necessary
to
remove
the
two
bottom
shipping
bolts
holding
the
orange
shipping
plates
to
the
stationary
cradle
.
With
these
bolts
removed
,
the
breaker
may
be
cranked
(
counterclockwise
)
to
its
open
position
and
then
fully
withdrawn
.
In
the
withdrawn
position
,
the
remaining
four
shipping
bolts
and
orange
plates
should
be
removed
and
discarded
.

must
be
stored
in
a
ventilated
room
anc
protected
from
dust
and
water
by
means
of
non
absorbent

to

the
operator
.
To
fully
charge
the
springs
manually
requires
approximately
15
reversals
or
oscillations
of
the
handle

The
control
panel

OPERATION
1
.
Manually
Operated
Breakers
With
the
manually
operated
SSPB
breaker
,
a
simple
rotary
motion
of
the
operating
handle
in
the
counterclockwise
direction
for
approximately
90
degrees
charges
the
springs
for
a
close
-
open
opera
-
tion
.
Rotation clockwise
back
to
its
normal
vertical
position
initiates
the
spring
release
for
closing
.
The
closing
speed
is
completely
independent
of
the
operator
.
A
position
indicator
located
on
the
front
escutcheon
indicates
the
position
of
the
main
contacts
:
red
for
"
on
"
or
"
closed
"
,
green
for
"
off
"
or
"
open
.
The
breaker
may
be
tripped
manually
by
depress
*
ing
the
manual
trip
button
.
Through
linkages
,
this
action
causes
the
mechanism
trip
latch
to
be
dis
-
placed
collapsing
the
operating
springs
and
thereby
opening
the
breaker
contacts
.
If
breaker
is
equipped
with
a
lock
-
out
device
or
undervoltage
release
,
refer
to
paragraph

operating
instructions
.
(
buttons
are
furnished
,
one
for
initiating
closing
of
main
contacts
(
red
)
and
one
for

(
green
)
.
In
addition
,
a
spring
indicator
is
Included
(
yellow
)
for
charged
,
and
(
black
)
for
discharged
condition
.

.
Electrically
Operated
Breakers
For electrical
operation
,
a
fractional
horsepower
,
high
torque
gearmotor
provides
energy
for
charging
the
springs
.
Charging
requires
approximately
5
seconds
.
Recharging
takes
place
automatically
after
the
breaker is closed
.
A
limit
switch
removes
the
gearmotor
supply
voltage
at
the
end
of
travel
.
The
supply
voltage
at
the
motor
terminals
may
be
between
90
to
110
%
of
the
rated
voltage
.
After
the
springs
are
charged
,
the
closing
springs
are
held
by
an
electromagnetically
operated
latch
.
When
the
breaker
is
closed
by
depressing
the
manual
close
button
located
on
the
front
escutch
-
eon
the
closing
latch
Is
displaced
,
thereby
col
-
lapsing
the
springs
and
closing
the
main
contacts
.
This
action
is
initiated
with
remote
closing
by
energising
the
electromagnet
.
The
breaker
may
be
manually
tripped
locally
or
electrically
tripped
from
remote
locations
.
In
the
event
of
power
loss
,
it
is
possible

ly
charge
the
springs
of
an
electrically
operated
breaker

.
The
emergency
operating
handle
is
identical
in
appearance
to
the
handle
used
on
manually
operated
breakers
.
The
method
of

Safety
Tripping
If
the
breaker
is
inserted
or
withdrawn
with
its
main
contacts
in
the
closed
position
,
a
mechanical
linkage
automatically
trips
the breaker
before
separation
of
the
main
contacts
during
withdrawal
or
before
closing
of
the
main
contacts
during
insertion
.
The
same
device
prevents
the
closing
of
the
breaker between

Should

,
an
