Updated July 14, 2008 system. If you power off the unit by pressing and holding the power switch, some programmed events do not function until the unit is powered on again. Examples of these programmed events are IBM Wake on LAN®, and others. Uninterruptible power supply (optional) The technical characteristics of the uninterruptible power supply (UPS) are as follows: v Capacity: 500 VA/300 W v Run time: 2.5 minutes minimum at full-rated (500 VA) load with a new, fully-charged battery v Output voltage in battery mode: 113 V AC ± 10% for low range; 220 V AC ± 10% for high range. v Frequency (in backup mode): 60 Hz ±3 Hz for line frequency > 55 Hz; 50 Hz ±3 Hz for line frequency < 55 Hz (output waveform is a stepped sinewave approximation) v Transfer time:

system.
If
you
power
off
the
unit
by
pressing
and
holding
the
power
switch,
some
programmed
events
do
not
function
until
the
unit
is
powered
on
again.
Examples
of
these
programmed
events
are
IBM
Wake
on
LAN
®
,
and
others.
Uninterruptible
power
supply
(optional)
The
technical
characteristics
of
the
uninterruptible
power
supply
(UPS)
are
as
follows:
v
Capacity:
500
VA/300
W
v
Run
time:
2.5
minutes
minimum
at
full-rated
(500
VA)
load
with
a
new,
fully-charged
battery
v
Output
voltage
in
battery
mode:
113
V
AC
±
10%
for
low
range;
220
V
AC
±
10%
for
high
range.
v
Frequency
(in
backup
mode):
60
Hz
±3
Hz
for
line
frequency
>
55
Hz;
50
Hz
±3
Hz
for
line
frequency
<
55
Hz
(output
waveform
is
a
stepped
sinewave
approximation)
v
Transfer
time:
<8
ms
typical,
10
ms
max,
AC
to
battery
The
characteristics
of
the
batteries
are
as
follows:
v
Replaceable
by
persons
with
typical
PC
hardware
upgrade
skills.
v
Recharge
time
is
8
hours
typical,
with
a
maximum
of
16
hours
for
a
fully
depleted
battery.
v
Battery
type
is
12-V,
5-AH,
sealed,
leak-proof,
maintenance-free
lead-acid
type.
Battery
life
With
a
new,
fully-charged
battery,
the
UPS
is
capable
of
delivering
full
output
for
2.5
minutes.
Typical
POS
configurations
require
much
less
power.
A
typical
system
unit
with
LCD
operator
display
can
last
15
minutes
with
a
new,
fully
charged
battery,
depending
on
print
activity
and
60
minutes
if
the
terminal
is
in
standby
mode.
The
battery
charge
capacity
decreases
over
time
and
this
decrease
is
accelerated
by
heavy
usage.
Regular
deep
discharges
of
the
battery
can
dramatically
reduce
its
useful
service
life.
The
useful
life
of
a
battery
in
a
typical
environment
is
one
to
three
years.
Input
voltage
The
UPS
option
cannot
sense
low-
versus
high-line
voltages.
Separate
units
are
designed
for
low-
and
high-line
voltages.
Units
cannot
be
converted
between
high-
and
low-line
voltage.
Figure
10
on
page
12
shows
the
power
outlets
and
connectors
of
the
UPS.
Attention:
Damage
to
the
UPS
will
occur
if
incorrect
line
voltage
is
applied
to
the
unit.
System
unit
interface
The
UPS
has
an
RS-232
(EIA
232)-compatible
output
that
can
connect
to
one
of
the
system
unit
RS-232
ports
to
communicate
UPS
status
(AC
power
loss,
low
battery)
to
the
operating
system
(OS),
or
application.
The
interface
is
compatible
with
the
Microsoft
Windows
default
UPS
implementations.
