The
System
B
or
System BfS3
can
be
ordered
for
either
llS
or
22S
volt
power
sources.
Make
sure
that
the
system
to
be
installed
has
the
proper
p::>wer
supply
for
the
power
supply
in
your
region.
It
is
recanmended
but
not
required
that
the
power
line
to
v.hich
the
canputer
is
comected
be
a
"dedicated"
power
line;
that
is,
the
line
canes
directly
from
the
building's
p::>wer
source,
no
other
devices
except
another
System
B
making
use
of
it,
and
that
it
is
well
grounded.
'!he
intent
in
this
recanmendation
is
to
eliminate
electronic
"noise"
on
the
power
line
which
can
affect
the
reliability
of
the
system,
and
to
avoid
the
loss
of
data
if
a
circuit
breaker
is
tripped
because
another
device
short
circuits
or
too
many
devices
are
connected.
It
is
particularly
critical
that
heavy
machinery
not
be
comected
to
the
same
p::>wer
line.
I):)
not
install
IOOre
than
two System
B's
per
2SA
circui
t.
Extension
cords
are
not
recanmended.
Special
air-conditioning
and
raised
floors
are
not
required
for
a System
B.
It
will
function
in
any
nonnal
office
environment.
Do
not
install
a System B
in
an
abnormally
dusty
or
dirty
environments,
due
to
the
effect
on
the
disk
drives
and
diskettes.
Make
sure
that
there
is
adequate
area
for
all
equipnent,
and
that
there
is
adequate
desk
space
next
to
the
console.
'!he
printer
MUST
Nor
be
placed
on
top
of
the
computer
mainframe.
The
console
should
be
low enough
for
comfortable
typing.
'!here
must
be
some
space
on
the
left
side
and
in
back
of
the
computer
mainframe,
for
ventilation.
Make
sure
that
the
console
is
not
directly
opposite
a
bright
open
window,
which
will
create
glare
on
the
surface
of
the
screen.
If
the
carpet
in
the
canputer's
area
is
a
shag
or
thick
carpet,
especially
if
there
is
a
lot
of
foot
traffic
near
the
computer
or
if
the
operator's
chair
has
rolling
casters,
there
may
be
a
build
up
of
static
in
the
operator
and
passing
people
that
can
discharge
into
the
system
and
cause
the
system
to
malfunction
or
crash.
If
you
anticipate
or
experience
this
problem,
spray
the
carpet
in
the
machine's
vicinity
once
a
IOOnth,
or
IOOre
often
as
needed,
with
anti-static
spray,
available
in
many
electronic
supply
and
carpet
distributors.
If
the
system
is
still
affected
by
static,
we
recommend
purchase
of
a
3M
anti-static
mat
to
be
placed
on
the
floor
in
the
canputer's
area.
