INTRODUCTION
Type
"AL"
Low-voltage
AC
Power
Circuit
Breakers
may
be
furnished
for
mounting
in
any
one
of
three
ways: (1) in
metal-enclosed
switchgear
of
the
draw-out
type; (2) in
individual
metal enclosures
(draw-out
type);
or
(3)
for
stationary
mounting
in a customer's
ow
n
enclosing
case
or
switchboard.
All
"RL
"
circuit
breakers are
completely
assembled, tested, and calibrated at
the
factory
in
a verti-
cal
position
and
must
be so installed
to
operate
properly
.
Customer's
primary
connections
must
be adequately
braced
against
the
effects
of
short
circuit
currents
to
pre-
vent overstressing
the
circuit
breaker
terminals.
RECEIVING
AND
INSPECTION FOR
DAMAGE
Immediately
upon
receipt
of
this
equipment,
carefully
remove all packing braces. Examine parts and
check
them
against
the
packing
list
and
note
any
damages
incurred
in
transit.
If
damage
is
disclosed, a
carrier
inspection
must
be arranged
for
by
consignee
within
15
days
of
receipt
of
equipment.
If
equipment
is
shipped
F.0 .8. Destination,
the consignee
must
obtain
the
original
of
the carrier
inspection
report
and
notify
Siemens-Allis immediately.

You
must
obtain

days
of
receipt
on
damaged equipment.
Two
shipping
methods are used with "
RL"
circuit
breakers:
1.
Individually
skidded
with
protective
covering.
2.
Within
a
cubicle.
Circuit
breakers.
shipped
in
their
cubicles
are
blocked
to
prevent
accidental
tripping
during
shipment.
Note
all
caution
tags, remove
block-
ing
bolts,
and
open
circuit
breaker
contacts
before
installation.
STORAGE
When
circuit
breakers are stored,
wrap
or
cover
them
with
a
non
-
absorbent
material
to
protect
them
from
plaster
,
concrete
dust,
moisture
or
other
foreign
matter
.
Do
not
expose
circuit
breakers
to
the
action
of
corrosive
gases
or
moisture.
In
areas
of
high
humidity
or
temperature
fluc-
tuations
, space heaters
or
the
equivalent
should
be
pro-
vided.
INSTALLATION
GENERAL
The
"
RL
"
Low-voltage
AC
Power
Circuit
Breaker
is
com-
pletely
adjusted, tested,
and
inspected
before
shipment.
However
, a
careful
check
should
be
made
to
be
certain
that
shipment
or
storage has
not
resulted in
damage
or
change
of
adjustment. Circuit breakers
and
their
enclo-
sures
should
be installed in a clean,
dry
,
well
-ve
ntilated
area in
which
the
atmosphere
is
free
from
destructive
acid
or
alkali fumes. For
stationary
breakers
and
c
ustomer
enclosures,
the
factory
should
be
consulted
for
minimum
clearances
and
required ventilation
openings
.
If
no
t
enclosed,
they
must
be
mounted
high
enough
.
to
prevent
injury
to
personnel
eithe
r from
circuit
interruption
,
or
from
moving
parts
during
automatic
opening
of
the
circuit
breaker.
