IMPORTANT SAFETY INSTRUCTIONS

TOSHIBA
1.0 Inspection/Storage
1.1 Inspection of the new UPS equipment
UponreceiptoftheUPS,acarefulinspectionforshipping damage should be made.
AfterUncrating:
1) Checktheunitfor loose, broken,bentorotherwisedamagedparts. If damage
hasoccurredduringshipment,keepalloriginalcratingandpackingmaterials
for return to shipping agent. Warranty will not apply to units which are damaged
duringshipment.
2) Check to see that the rated capacity and the model number specified on the
nameplateconformtotheorderspecifications.
1.2 Storage of UPS equipment.
If the UPS equipment is to be subject to long or short term storage the following
guidelinesshouldbeused.
Avoid:
1) Storage in sites subject to extreme changes in temperature or high humidity.
2) Storage in sites subject to exposure of high levels of dust or metal particles
3) Storage on inclined floor surfaces or in sites subject to excessive vibration.
Beforestoring:
1) Chargetheunitsbatteries.
2) Place the UPS ON/OFF switch in the OFF position.
Storing:
1) Store within a temperature range of -20 to 40 deg C (-4 to 104 deg F).
2) For best results, store the UPS in the original shipping container and place on a
woodormetalpallet.
3) Theoptimumstorage temperatureis21degC (70 degF).Higherambient
temperaturescauseUPSbatteriestoneedrechargingmorefrequently.
Afterstoring:
1) Ifstoredin an ambienttemperatureunder20deg C(68degF);recharge the
batteriesevery9months.
2) If stored in an ambient temperature of 20 to 30 deg C (68 to 86 deg F);
rechargethebatteriesevery6months.
3) If stored in an ambient temperature of 30 to 40 deg C (86 to 104 deg F);
rechargethebatteriesevery3months.

2.0 Precautions
2.1 InstallationPrecautions
1) Install the unit in a well ventilated location; allow at least 10 cm (4 inches) on
allsidesforairventilationandformaintenance.
2) Install the unit in a stable, level, and upright position which is free of vibration.
3) Installtheunitinanenvironment wheretheambient temperatureis
between 0 to 40 deg C (32 to 104 deg F).
4) Do not install the UPS in areas that are subject to high humidity.
5) Do not allow direct sunlight to shine on the unit.
6) Do not install the UPS in areas which are subject to contamination such as
highlevelsofairborne dust, metalparticles,orinflammablegas.
7) Avoid installation near sources of electrical noise and always make sure that
the unit ground is intact to prevent electrical shock and to help reduce
electrical noise.
8) Do not install where water or any foreign object may get inside the UPS.
9) ThisUPSgeneratesandcanradiateradio-frequencyenergyduringoperation.
Although RFI noise filters are installed inside the unit there is no guarantee
thattheUPSwillnotinfluencesomesensitivedeviceswhichare operating
close by. If such interference is experienced, the UPS should be installed farther
awayfromtheeffectedequipmentand/orpoweredfromadifferentsourcethan
thatoftheaffectedequipment.
2.2 PrestartPrecautions
1) Before connecting the UPS to a power source; move the ON/OFF switch, on
the front panel (See Section 8.1), to the OFF position.
2.3 Operating Precautions
1) TheUPSshouldnot be poweredupuntiltheentireoperation manual has
beenreviewed.
2) Theinputpowersource voltage must be within +10% to -30%of the rated input
voltage.Theinputfrequencymustbewithintheratedinputfrequencyrange.
Voltagesandfrequenciesoutside ofthepermissibletolerancerange maycause
internalprotectiondevicestoactivate.
3) The UPS should not be used with a load whose rated input is greater than the
ratedUPSoutput.
4) Do not use the UPS to provide power to motors that require high starting current
or a long starting time such as vacuum cleaners and machine tools.
5) Do not insert metal objects or combustible materials in the unit's ventilation slots.
6) Do not place, hang, or paste any objects on the top or on the exterior surfaces
of the UPS.

3.0 Product Description
3.1 Theory of Operation
An uninterruptible power supply is a system that is installed between the commercial
powerandtheload equipment. Itisusedduringshort-term blackouts orbrownouts.The
UPS providessteadyacoutputpowerduring thesecommercialpowerinterruptions.
This power is provided for a long enough time so that the load can be shutdown in an
orderlyfashion.Thispreventslossofdataandpossibledamagetobothhardwareand
software.
During normal operation the UPS uses commercial ac power. In addition, it also takes
in all of the high voltage spikes and transients caused by switching and faults, and all
of the common mode and normal mode noise which is associated with commercial ac
power. The UPS converts it all to flat dc power. From this dc power, the UPS charges
itsbatteriesandgeneratesitsownextremelyhighqualityacwaveformoutput.The
result of this process is maximum power conditioning.
IftheacpowersuppliedtotheUPSdropsbelowaspecifiedvoltage level, the unit's
batteriesautomaticallybeginsupplyingpowerinsteadof receiving it. Thisinsuresthat
theloads connected to the UPS continue to receive power with no interruption. When
acinputpowerbecomesavailableagain,operationreturnstonormal.Theunit's
batteriesbegin to recharge so they will beready for the next power interruption.
3.2 Application and Use
Toshiba's1400Seriesofon-lineuninterruptiblepowersupply(UPS)systemsprovide

equipment.Thiscanrangefrom wordprocessorsandpersonalcomputerstomini-

thebatteryvoltagedropsbelowstandardduringuse.Thisisanadditionalaid to help
inretainingthevaluable officedatabanks.All unitsallowforcomputerinterfacing and
and an external battery pack option (see specifications).
3.3 Power Backup
Whenanelectricalpowerfailureoccurs,theUPSunit'sinternalmaintenance-free
batteriesautomaticallysupplyback-uppowertotheloadwithoutinterruption.For
example, when used to support a computer, the UPS back-up assures enough
additional time to complete the activity and store data. This allows an orderly shutdown
afterapowerfailurehasoccurred.
3.4 Power Conditioning
When commercial power is present, the UPS supplies conditioned power to the load
while maintaining its batteries in a charged condition. The UPS protects against the
normaleverydayproblemsassociatedwithheavyuseofrawcommercialacpower,
includingpowersags,surges,signalinterference,andspikes.Thisprotectionkeeps
power-lineproblemsfromreachingtheloadswhere theycancauseequipmentto

Power flow in AC input mode for 1500 and 2000 VA Models
Both of the above illustrations show circuit power flow in the ac input mode.
The UPS unit's rectifier, included in a boost chopper circuit, converts ac input
powertodcpower.This dcpowerrunstheunit'stransistor inverter andcharges

When commercial ac power failures occur, the UPS's batteries instantly begin
supplying dc voltage to the UPS's main inverter circuit. This circuit changes
(inverts)thedcpowerintoacpower.Theacpowerisavailableattheunit's
output receptacles. This back-up process will continue until the UPS's battery
voltage drops below a specific minimum level. When this occurs, the batteries
will stop supplying power to the load. This minimum level is the rated minimum
voltage(Vmin).Theratedbatteryvoltagechartonpage5-6(SeeSection5.4
for battery backup time) shows (Vmin).

IftheUPSunit isoverloadedordevelops aninternalfault,thepower flowis
automatically switched from the unit's main circuit to the bypass circuit mode.
Powerflowthroughthebypassisshown in the above illustrations. Thischange-
overoccursautomaticallyinapproximately4milliseconds. The switching period
is not long enough to cause interruptions to occur in most UPS equipment loads.
Afterrepairingthe causeoftheinverter shutdown,theenergyflowmustbe
transferred manually from the UPS's bypass circuit back to the inverter circuit.
This is done by toggling the ON/OFF switch (on the unit's front panel) first to
OFF and then back to ON. This action resets (clears) the fault.

Notes:
1) TheUPS'sRECT/CHOPPERandINVERTER,althoughseparateelectrical
circuits, are physically located on the same heat sink. This is applicable to all
models.
2) Thetwo UPSrearpaneloutputreceptaclesaresuppliedfromtheUPSinverter
section through separate 15A output fuses (applies to the 1500 and 2000 VA
model only). Thus, an overload on one of the receptacle sets can cause a loss
of power to it while the other receptacle set remains active. If all of the UPS
indicatorlightsappearnormal and powerisnotavailableat oneofthereceptacle
sets, check the associated output fuse.

Therecharge process usually consists of three periods. During the first period,the
current is maintained at approximately 0.4 amperes. In the second period, the constant-
voltage control starts and the current gradually decreases as the batteries continue to
charge. In the third period, a slight current flows into the batteries to keep them fully
charged.Afteracomplete discharge, afullrechargeusuallyrequires24 hours(90%
rechargein8hours)forthe500through750VAmodels and 30 hours (90% recharge in
8hours)forthe800through2000VAmodels.
