Product Description
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 shut down 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 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 the batteries and generates its own extremely high
quality ac waveform output. The result of this process is maximum power conditioning and regulation.
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.
Application and Use
Toshiba's 1600 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.
Output Rating
Toshiba's 1600 Series (240/208V) offers UPS models with the following capacities and voltages:
When the unit is operating at 240 volts, UPS models UE3G2L024C6(T)(P#), UE3G2L036C6(T)(P#),
UE3G2L060C6(T)(P#), and UE3G2L080C6(T)(P#) will supply the maximum rated power to the loads
(output capacity: 2.4/3.6/6/8 kVA). If the unit is operating at 208 volts, UPS output capacity will be
reduced to 87% of maximum rated power capacity (output capacity: 2.08/3.12/5.2/6.93 kVA).
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, every day
problems associated with heavy use of raw commercial power, including power sags, surges, signal
interference, and spikes. This protection keeps power-line problems from reaching your load, where
they can cause equipment to operate erratically, or damage software and hardware.

Inspection/Storage/Disposal
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.
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) Allow UPS to be operated for 24 hrs. to ensure that the batteries are fully charged.
2) Stop the unit (see "Stopping the UPS" on page 39).
3) Place the unit's MCCB switch (see page 44 for location) in the "off" 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.
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 dispose of improperly.
Please help our Earth by contacting the environmental protection agencies in your area, the battery
manufacturer, or call Toshiba toll-free at [phone] for more information about recycling.

Precautions
Installation Precautions
1) Install the unit in a well ventilated location; allow at least 10 cm (4 inches) on all sides
for air ventilation and for maintenance.
2) Install the unit in a stable, level, and upright position which is free of vibration.
3) Install the unit where the ambient temperature is within the correct operating range
(see UPS Specifications pages 18 -19).
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 high levels
of airborne dust, metal particles, or inflammable gas.
7) Avoid installation near sources of electrical noise and always make sure that the unit earth
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) This UPS generates and can radiate radio-frequency energy during operation. Although RFI
noise filters are installed inside the unit there is no guarantee that the UPS will not influence
some sensitive devices which are operating close by. If such interference is experienced,
the UPS should be installed farther away from the affected equipment and/or powered from a
different source than that of the affected equipment.
10) UsershouldprovideoutputovercurrentprotectionforhardwiredUPSversions.
See Safety Instructions on page 8 for the correct device rating.
Operating Precautions
1) The UPS should not be powered up until the entire operation manual has been reviewed.
2) The input power source voltage must be within +10% to -30% of the rated input voltage. The
input frequency must be within the rated input frequency range. Voltages and frequencies
outside of the permissible tolerance range 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 for lock rotor current required).
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.

UPS Stop Signal Operation
When the UPS stop signal is sent to the UPS through pin 2 and 3 of the external contact interface,
it is possible to automatically reset the following operation systems (OS), which can automatically
implement the shutdown function and restart the operation:
Applicable OS: Windows NT, IBM OS/2 LAN server, LANtastic
Notapplicable: NetWare
When the power fails, the OS detects the power failure signal from the UPS and starts the
shutdownprocess.
At the end of the shutdown process, the OS outputs a stop signal to the UPS, and the UPS stops.
When the power recovers, the UPS automatically starts output and restarts the OS. Even
when the power recovers while in a shutdown process, the UPS temporarily cuts off the
output (10 - 20 seconds) and then restarts the OS within 10 minutes after the recovery from
power failure. In this case the UPS cuts off output even with normal input power. Connect the
UPS stop signal of the external contact interface only for the automatic processing so that the
UPS output will not be cut off by mistake. If a stop signal is input to the UPS 10 minutes or
more after the recovery from a power failure, then the UPS ignores this signal and continues
to output power.
If the computer is started/restarted within 10 minutes after the recovery from a power
failure, the power supply may be reset while the computer is restarting.

Operating the UPS
Battery Backup Time and Discharge Process
The UPS unit's batteries provide about 7 minutes of back-up time for the 2.4 kVA, 3.6 kVA, 6 kVA,
and 8 kVA models. These times are valid when the unit is operating under full load (output
capacity is derated to 87% of nominal capacity when the output voltage is 208 Vac). When
these models are operating at half load, the batteries can provide about 20 minutes of back-up
time. The exact length of these times will depend on the UPS model used, condition of the
batteries, amount and type of load, temperature and other variables. See battery backup time
in 'Standard Specifications' beginning on page 18.
The following illustration graphically shows the battery discharge process at full load conditions.

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
also at what level the low-voltage condition will cause the unit to automatically shut down.

Voltage Current
The recharge process usually consists of three periods. During the first period, the current is
maintained at approximately 1 ampere. This current limit is the maximum value that can be
used to charge the batteries (for minimal recharge time) while assuring safety and long battery
life. In the second period, constant-voltage control starts and current gradually decreases as
the batteries charge to their normal fully charged state. In the third period, a slight "trickle"
current continues to flow into the batteries to keep them fully charged and "floating" at the
normal Vdc level. A full recharge usually requires 24 hours (90% recharge in 10 hours) after
a complete discharge.
The following chart shows the rated maximum and minimum battery voltages, and the
charge current for each of the sizes.
