About your UPS
An UPS (Uninterruptible Power Supply) is basically a high-tech filter
between the local power company and your electronic equipment. Normally
in the USA, the power companies provide dependable service. But power
outages still occur. If you work regularly with computers, you’ve probably
experienced several occasions when the “lights went out” while you were
working (or playing) on your computer. Perhaps you’ve even lost hours of
work because you forgot to “save” your files. Other forms of power distur-
bances include spikes & surges, frequently occurring during thunderstorms,
that can blow fuses and even destroy equipment. A properly designed UPS
can filter most of such power problems and provide clean, uninterrupted
(hence the name) power to protect your valuable equipment and data.
Features of your TSi Power UPS
• TSi Power’s UPS-550B & UPS-720B series perform the basic function
explained above, and much more. Its architecture is that of a standby UPS
(or off-line UPS), whose inverter is only activated when the line AC becomes
irregular. This has the advantage of lower cost and greater reliability, since
the electronic components don’t have to work all the time. The traditional
disadvantage of off-line UPSs, longer switchover time, has been virtually
eliminated by advanced detection and transfer electronics that reduce the
switchover time to 4 to 8 ms.
• The UPS-550B & UPS-720B can communicate with most popular
network OS’s such as Novell NetWare, UNIX, AppleShare and Windows
3.11/95/NT to provide power protection and automatic shutdown to
network users.
• The UPS-550B & UPS-720B also have remote dial-up capability, which
lets you power up your computer or other equipment via the phone or
modem at any time from anywhere.

Detailed Operating Instructions
If you just want to get the UPS up and running quickly, see p.1 for Quick Installation
Instructions.
(1) Place the unpacked UPS near a grounded (3-pronged) AC outlet, rated
at 120 volts, 60 Hz, 15 amps. Make sure that the POWER switch is in the
OFF position and that the REMOTE switch is in the NORMAL position.
(2) Plug in one end of the enclosed AC power cord to the rear of the UPS,
and plug the other end into the AC outlet. The green light marked AC ON
should now turn on.
(3) Plug in all the equipment that you want backed up into the sockets
labeled UPS OUTPUT, but make certain that the maximum power rating is
not exceeded. The maximum amount of power that each of your equipment
will draw should be printed in the rear of each equipment, near the power
cord. Their sum should not exceed 360 watts for UPS-550B and 500 watts
for UPS-720B.
(4) Turn on the power switch. If you have connected more than the rated
load to the UPS, it will shut off in several seconds. Remove the excess load
and try again by turning the UPS off and then on with the power switch.
Make sure that the equipment connected to the UPS is working properly.
[Note: depending on the battery voltage, the BAT CHRG light (red) may be
on, indicating that the battery is being recharged. This is normal.]
(5) As a test, you may simulate a power outage by unplugging the UPS
power cord from the AC outlet. All your equipment connected to the UPS
should continue working without interruption. The UPS has just made a
switchover from AC to inverter. The INV ON light (yellow) will flash and
an audible alarm should “beep” about once a second (if the ALARM switch is
in the ENABLED position.) WARNING: Under no circumstances should you
connect more than the rated load of the UPS while the INV ON light is flashing.
(7) You can turn off the alarm placing the ALARM switch in the DIS-
ABLED position. However, if the power outage continues and the battery
voltage drops below a certain threshold (~22VDC), the audible alarm will
Caution: To protect against shock
hazards, do not use a 3-prong to 2-
prong adaptor with this UPS.
¨
A typical desktop PC or Mac with
VGA monitor draws between 200
and 300 watts. A fully loaded file
server may draw upto 500 watts.

If you are not sure about how
much power your equipment
draws, see accompanying
table, “Load Ratings for
Typical Equipment”

sound (as a continuous tone) regardless of the position of this switch. This
means that there is about 2 minutes of backup time left (at full load.)
(8) Plug the power cord back into the AC outlet. The AC ON light will
come back on and after a few seconds, the INV ON light will go off. The
UPS has just made a transfer from inverter back to AC. All your equipment
should continue to operate without interruption.
(9) If the power outage had been real and prolonged, the UPS may have
shut off due to low battery voltage. If AC power returns, the UPS will
resume normal operation and charge the batteries. Turning the power switch
off and on again will restart the UPS regardless of battery voltage or AC
power condition.
(10) In some rare cases you may find that after leaving the UPS unattended
for a power outage lasting several days, the UPS will not turn on and operate
even after AC power returns. This is because the protection circuitry has
activated to prevent damage to the batteries. To restart the UPS, first make
sure that the UPS is plugged in to an AC outlet and that the green AC ON
light is on. Next, turn off the UPS and leave it off for at least 5 minutes.
Now turn the UPS on again. The UPS should come back on and the
batteries will begin to recharge. Allow the batteries to recharge for at least 24
hours.
(11) When an overload occurs and the UPS shuts off, you must remove the
excess load and reset the UPS by turning it off and then on, before the UPS
will resume proper operation.
¨
Your UPS will hold up a typical
desktop PC for about 10 to 20
minutes during a power outage.
However, as the batteries inside
your UPS get older, your holdup
times will go down. You may wish
to test your UPS about twice a year
to prevent against battery failure.
¨
Hint: Your UPS can self-start, i.e.
start providing AC power even
when there is no utility AC power.
Just turn on the Power Switch.
Your UPS can communicate with a network file server, UNIX workstation or
a PC using the alarm interface port. This port provides functions compatible
with Novell, Windows 3.1/95/NT, Vines, 3COM, Lantastic, AppleShare and
other network operating systems. With the proper software and interface
cable, your file server can warn users of a power failure and, if necessary, shut
down safely and automatically. For network installation, please refer to the
instructions accompanying the software and your network documentation.

The diagram below shows the pin-outs of the alarm interface port.
If you wish to use the alarm interface port for custom applications, take into
consideration the following limitations.
• Pins 3, 5 & 6 are open-collector outputs, limited to switching 40V and
sinking 20mA of current.
• Pins 2 and 7 are RS-232 compatible outputs. They will switch from RS-
232 low (about -10V) to high (about +10V), and can drive a 25mA load.
• A positive (> 5V) pulse lasting longer than 1/4 second at pin 1 is required
to shut down the UPS during power failures. This pin is inactive when the
AC mains is normal.
• For best performance, your alarm monitoring circuit should be isolated (via
transformers, relays or optocouplers) from the rest of your network.
Should you have any questions
related to the UPS hardware,
please call TSi Power at (715)
623-0636. For software related
questions, please contact your
software vendor first.

Modem Data Cable
Remote UPS Access
The power to the equipment connected to your UPS can be controlled
remotely by dialing in to a phone line connected to the UPS.
(1) Make the connections to the phone line, your phone and modem (if
any) as shown above. The LINE connector of the UPS always connects to
the incoming phone line. The MODEM connector of the UPS connects to
telephone equipment such as phone, modem or fax.
(2) When you are ready to place your equipment in the remote mode, turn
the MODE switch (the rotary key switch) to the REMOTE position.
[Caution: the power to your equipment will be immediately removed. Make sure
you have saved all your work and were ready to shut off the system before taking
this step.] The amber light marked REMOTE should flash. Leave the UPS
on. The system is now in the REMOTE mode.
(3) When you want to turn on the equipment connected to the UPS at a
later time from another location, simply dial the number of the phone line to
which the UPS is connected. After 3 to 5 rings, the UPS will detect the
ringing and supply power to the equipment. Also, if the phone line becomes
busy—e.g. when a modem establishes connection—the UPS will continue to
supply the equipment with power.
(4) When you hang up the phone, the UPS will remove power to the
equipment after 30 to 40 seconds. You can redial the number and keep the
equipment on within this time.
The UPS will not interfere with the
modem or telephone..
¨
It may take about a minute
after the UPS is turned on for
the first time before the MODE
switch becomes operational.

For example, suppose you wished to access a remote PC from your home.
Normally, you would have to keep your remote PC turned on all the time,
thus reducing its life and wasting electricity. With yourTSi Power UPS, you
can keep the remote PC off, and only turn it on when necessary. You would
configure the remote PC to run a communications program—such as
pcAnywhere or Carbon Copy—upon boot-up, and then place the UPS in the
REMOTE mode, turning the remote PC off. At home, when you need to
access the remote PC, you would dial the UPS, turn on the remote PC, and
let your home modem and remote modem establish a connection. When
finished, you can hang up, and power to the PC will be turned off automati-
cally after 30 to 40 seconds. This process can be repeated as many times as
necessary.
Many other applications are possible, to make the UPS an integral part of
your computer system.

prepared for the approximately 40lbs of

or plywood wall should be at least 1/2” thick.
A steel wall should be at least 1/8” thick.
Mounting on plaster wall is not recom-
mended.

4 wood screws size #10 or larger should be
used to secure the units ( C). If the wall is
made of steel, either 4 studs or 4 threaded
holes of size #10 or larger must be placed at
the proper location before attempting to mount the unit. The holes should
be placed 7” apart vertically, and at a horizontal distance of 16-1/2” (see
figure).
