Product Description
1.1
Theory of Operation
An uninterruptible power supply is a system that is installed between the commercial
power and the load equipment. It is used during short-term blackouts or brownouts. The
UPS provides steady ac output power during these commercial power interruptions.
This power is provided for a long enough time so that the load can be shutdown in an
orderly fashion. This prevents loss of data and possible damage to both hardware and
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
its batteries and generates its own extremely high quality ac waveform output. The
result of this process is maximum power conditioning.
If the ac power supplied to the UPS drops below a specified voltage level, the unit's
batteries automatically begin supplying power instead of receiving it. This insures that
the loads connected to the UPS continue to receive power with no interruption. When
ac input power becomes available again, operation returns to normal. The unit's
batteries begin to recharge so they will be ready for the next power interruption.
1.2
Application and Use
Toshiba's 1500 and 1500 Plus Series of on-line uninterruptible power supply (UPS)
systems provide continuous computer-grade ac power in a compact, high performance,
and energy efficient unit. The UPS unit assures safe and reliable operation of critical
office equipment. This can range from word processors and personal computers to
mini-computers and local area networks. All units feature an audible alarm which sounds
if the battery voltage drops below standard during use. This is an additional aid to help
in retaining the valuable office data banks. All units allow for computer interfacing and
an external battery pack option (see specifications).
1.3
1.4
Power Backup
When an electrical power failure occurs, the UPS unit's internal maintenance-free
batteries automatically supply back-up power to the load without interruption. 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
after a power failure has occurred.
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
normal everyday problems associated with heavy use of raw commercial ac power,
including power sags, surges, signal interference, and spikes. This protection keeps
power-line problems from reaching the loads where they can cause equipment to
operate erratically, hard-disk crashes, or cause damage to hardware and software.

Inspection/Storage/Disposal
2.1
Inspection of the new UPS equipment
Upon receipt of the UPS, a careful inspection for shipping damage should be made.
After Uncrating:
1) Check the unit for loose, broken, bent or otherwise damaged parts. If damage
has occurred during shipment, keep all original crating and packing materials
for return to shipping agent. Warranty will not apply to units which are damaged
during shipment.
2) Check to see that the rated capacity and the model number specified on the
nameplate conform to the order specifications.
2.2
Storage of UPS equipment.
If the UPS equipment is to be subject to long or short term storage the following
guidelines should be used.
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.
Before storing:
1) Charge the units batteries.
2) Place the STOP/RUN switch in the STOP position.
Storing:
1) Store within a temperature range of -20° to 40° C (-4° to 104° F).
2) For best results, store the UPS in the original shipping container and place on a
wood or metal pallet.
3) The optimum storage temperature is 21° C (70° F). Higher ambient
temperatures cause UPS batteries to need recharging more frequently.
After storing:
1) If stored in an ambient temperature under 20° C (68° F); recharge the batteries
every 9 months.
2) If stored in an ambient temperature of 20° to 30° C (68° to 86° F); recharge the
batteries every 6 months.
3) If stored in an ambient temperature of 30° to 40° C (86° to 104° F); recharge the
batteries every 3 months.
2.3
Disposal
Please contact your state environmental agency for details on disposal of electrical
components and packaging in your particular area.
It is illegal to dump lead-acid batteries in landfills or to dispose of them improperly.

(STOP/RUN), on the front panel (See sections 9.1), to the STOP position.
3.3
Operating Precautions
CAUTION
1) The UPS should not be powered up until the entire operation manual has
been reviewed.
2) The input power source voltage and frequency must be within the specified
ranges (See Specification sections 4.1 and 4.2). Voltages and frequencies
outside of the permissible tolerance ranges may cause internal protection
devices to activate.
3) The UPS should not be used with a load whose rated input is greater than the
rated UPS output.
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 (oversizing

Power flow in AC input mode
The above illustration shows circuit power flow in the ac input mode. The UPS
unit's rectifier, included in a boost chopper circuit, converts ac input power to dc
power. This dc power runs the unit's transistor inverter and charges the batteries.
The boost chopper circuit maintains a constant voltage, with current limiting, for
charging the batteries and assures proper sine waveform generation for the
output current. The unit's batteries are maintained in a constantly charged state
when the UPS is in the normal operation mode. On the front panel, LED's labeled
"On Line" and "AC Input" should be on and the "Fault" LED should be off
(See Section 9.2 Panel Layout).

Power flow in battery backup mode
The above illustration shows circuit power flow in battery backup mode. 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) the dc
power into ac power. The ac power is available at the unit'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). The rated
battery voltage chart in section 5.6 (See Section 5.7 for battery backup time)
shows (Vmin). On the front panel, LED's labeled “AC Input” and “Fault” should be
off. The “On Line” and “Backup” LED’s should be on (See Section 9.2 Panel
Layout).

Power flow in circuit-bypass mode.
If the UPS unit is severely overloaded or develops an internal fault, the power flow
is automatically switched from the unit's main circuit to the bypass circuit mode.
Power flow through the bypass is shown in the above illustrations. This change-
over occurs automatically in approximately 4 milliseconds. The switching period
is not long enough to cause interruptions to occur in most UPS equipment loads.
The energy flow must be transferred manually from the UPS's bypass
circuit back to the inverter circuit after first correcting the fault. Toggle the
STOP/RUN switch (on the unit's front panel) first to STOP and then back to RUN.
This procedure resets the UPS and transfers back to inverter. During circuit-
bypass mode the AC-Input LED is ON, the On-Line LED is OFF, and the Fault
LED may be ON or OFF.(See Section 9.2 Panel Layout).

The recharge 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. After a complete discharge, a full recharge usually requires 24 hours (90%
recharge in 8 hours).

Battery Backup Time
The UPS unit's batteries provide about 5-12 minutes of back-up time depending on the
capacity of the UPS. These times are valid when a unit is operating under full load. When
the units are operating at half load, the batteries can power the load equipment about 3
times longer. The exact length of these times will depend on the UPS model used,
condition of the batteries, amount of load, temperature and other variables. See battery
backup time in the standard specifications Sections 4.1 through 4.2.
5.8
Battery Low Voltage Tolerances
Excessive discharge will cause the UPS unit's battery voltage to drop. The chart shown
below lists the voltage level at which each UPS unit's low-voltage alarm will sound and

Battery Check Function
Part of the UPS start-up procedure is an automatic 'Battery Check' to see if a problem
exists in the battery circuit. When the UPS is started it will begin operation in the bypass
mode. An automatic voltage level test of the batteries is made while operating in the
bypass mode for five seconds. A failure of this first test will activate visual and audible
alarms (see section 5.3.3 "battery problem"). If this test is passed, then the UPS will auto-
transfer from bypass mode to on line operating mode. A ten second automatic voltage
check of the batteries is made after the UPS has auto-transferred from bypass to on line
mode. Normal on line operation continues if the second test is passed. If the second test
fails, then the "Fault" LED will flash and up to three additional automatic battery voltage
checks are made at 3 hour intervals while the inverter continues to operate. If the
batteries are found to be normal during one of these three tests then the "Fault" LED
will stop flashing and normal inverter operation will continue. A failure of the third and
final check will activate visual and audible alarms (see section 5.3.3 "battery problem")
causing an auto-transfer back to bypass. If the batteries are indicated "bad" then
STOP the UPS and allow a 24 hour charge on the batteries before restarting.
5.10
System Reset
The UPS is reset by moving the STOP/RUN switch from "run" to "stop" and then back
to "run". Use the reset procedure to transfer from bypass back to inverter after a fault
occurs. Some faults may only be cleared by shutting down the UPS, waiting for all LED's
on the front panel to go off, and then restarting the UPS.

Preventive and Scheduled Maintenance/Parts Replacement
8.1
Preventive Maintenance
Toshiba's 1500 and 1500 Plus Series of uninterruptible power systems have been
designed to provide years of trouble-free operation requiring a minimum of preventive
maintenance.
The best preventive measure that the UPS user can take is to keep the area around the
unit, particularly the air inlet vents, clean and free of moisture and dust accumulations.
If the atmosphere of the installation site is very dusty, use a vacuum cleaner to
periodically remove dust accumulations from the system. Schedule authorized service
centers to perform internal parts inspections annually.
Before performing any maintenance, the technician should
be familiar with and follow the important safety instructions
located on pages vi and vii.
CAUTION
Proper maintenance of the battery system of this unit by a
qualified service technician is essential to the safety and
reliability of your UPS system. Refer to service manual.
WARNING
8.2
Parts Replacement
The following list shows intervals for periodic maintenance and replacement of certain
UPS parts.
1)
Batteries: VRLA batteries are maintenance free with respect to electrolyte only.
The charging voltage, temperature, performance and connection resistance must
be monitored periodically. Necessary corrective actions must be made in order to
assure safe reliable power is supplied by the UPS. The aforementioned items
affect the life of batteries, so replacement should be done once every 3 to 5 years
at a minimum. All of the batteries must be replaced at the same time.
Quarterly maintenance
a) Visual checks
1) Leakage
2) Corrosion on positive terminal
b) Check battery temperature at the negative terminal.
c) Measure and record the system float charging voltage.
d) Measure and record the individual units float charging voltage.
Semi-Annual maintenance
a) Repeat the quarterly checks.
b) Perform a 10 second high rate (e.g. 100 amp) load test on the
individual batteries.
c) Optionally test for the purpose of trending the battery over time.
d) Re-torque all inter-battery connecting hardware (if applicable).
e) Perform inter-battery connector resistance checks.
2)
3)
Aluminum electrolytic capacitors: Replace once every 5 years.
Fuses: Replace once every 7 years (see output fuse rating chart on the following
page).
4)
Cooling fan: Replace once every 3 years.
