9. Product Description
An uninterruptible power system (UPS) is a system that is installed between the commercial power and the
load equipment. The UPS provides steady AC output power during commercial power short-term blackouts
or brownouts. This power is provided for a sufcient amount of 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. It absorbs 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 clean DC power. From this 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 and regulation.
If the AC power supplied to the UPS drops below a specied 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.
9.1 Application and Use
Toshiba 1600XP Series of On-Line UPS provides continuous computer-grade AC power in a compact, high
performance, and energy efcient unit. The UPS unit ensures safe and reliable operation of critical ofce
equipment. All units feature an audible alarm which sounds if the battery voltage drops below a specied
minimum during use. This is an additional aid to help protect valuable ofce data banks. All units allow for
computer interfacing.
9.2 Output Rating
Toshiba 1600XP Series (208/240V) offers UPS models with the following capacities:
MODELOutput Capacity @ 240 VOutput kW @ .85PF 240 V
UH3G2L036C61T3.6 kVA3.1 kW

UH3G2L180C61T18 kVA15.3 kW
UH3G2L220C61T*22 kVA*18.7 kW*
All models are RoHS compliant with the batteries being exempt from the directive.
*NOTE: Derate to 18.7 kVA (15.9 kW) for 50 Hz operation.
9.3 Power Backup
When an electrical power failure occurs, the UPS’s internal 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 the data. This allows an orderly shutdown after a
power failure has occurred.
9.4 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 normal, everyday pr oble ms ass ocia ted
with unreliable 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.

10. Operating Modes
10.1 Static-Bypass (Stop operation)
If the UPS unit is severely overloaded or develops an internal fault, power ow is automatically switched
from the unit’s main circuit to the bypass circuit. Power ow through the bypass is shown in the following
illustration. This change-over occurs automatically in phase in less than one-quarter cycle of the input
waveform. The switching period is not long enough to cause interruptions to occur in most loads.
•If the power ow is transferred to the bypass circuit due to an internal fault the UPS will continue to
supply power to the load through the bypass and indicate a system fault message (see system fault
messages on pages 47–48).
•If the power ow is transferred to the bypass circuit due to an overload condition (see system warning
messages on pages 48–49), then the power ow will automatically transfer from the UPS’s bypass
circuit back to the inverter circuit after removing the overload if set to do so (AutoXfer parameter (Cmd
ID 660)).

10.2 On-Line (Run operation)
The following illustration shows circuit power ow when the UPS is operating normally in the On-Line
mode. The UPS rectier, including a boost chopper circuit, converts AC input power to DC power. The
boost chopper circuit maintains a constant voltage, with current limiting, for charging the batteries.
The inverter section generates a high quality sinusoidal output voltage. The unit’s batteries are always
maintained in a constantly charged state when the UPS is in the run operation mode.

The following illustration shows power ow during the 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 output of the
unit.
This back-up process will continue until the UPS’s battery voltage drops below a specic 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 on page 19 shows (Vmin). The battery backup time and discharge process is explained on page 19.

10.4 EPO (Emergency Power Off) Function
These units are equipped with terminals for receiving an emergency power-off (EPO) command via a
closed-contact switch at a remote location (see Terminal Block Details on page 11 and terminal block
location on pages 60-61). This safety feature enables quick shut-down of the UPS’s AC input breaker,
output and battery circuits.
Usually the emergency power off switch is installed in a central location that is easily accessible to
personnel concerned with the operation of the UPS unit and the load equipment connected to it. The EPO
function is initiated by pressing the switch to the closed (shutdown) position.
The effect of using the EPO switch is the same whether the UPS unit is in AC input mode, battery backup
mode, or the circuit bypass mode. The following gure shows the UPS condition after application of the
EPO switch.

10.5 Battery Backup Time and Discharge Process
The UPS batteries provide approximately 5-7 minutes of back-up time depending on the 1600XP unit kVA
rating. These times are valid when the unit is operating under full load and at the rated power factor. 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 ‘UPS Specications’ beginning
on page 53.

10.6 Battery Low Voltage Tolerances
Excessive discharge will cause the UPS battery voltage to drop. The chart shown below lists the voltage
level at which each UPS low-voltage alarm will sound and at what level the low-voltage condition will
cause the unit to automatically shut down.
The illustration below shows a graphical representation of the UPS battery recharge process after a full

The recharge process usually consists of three periods. During the rst 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 ow into the batteries to keep
them fully charged and oating at the normal Vdc level. A full recharge usually requires 24 hours (90%
recharge in 12 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.

11. Operating the UPS
The 1600XP should be installed by a certied electrician. Once installed, the 1600XP is designed to be
operated by any user. Anyone not familiar with this UPS should read the manual before attempting to
operate it.
11.1 Initial Startup (First Power-Up)
The rst time the UPS is activated after being shipped from the factory, these parameters need to be
set by the customer for site specic ratings. Input Rated Voltage, Output Rated Voltage, UPS Date, and
UPS Time.
The input frequency defaults to 60 Hz.
The rst screen displayed during the initial startup sequence requires the operator to select the nominal
Input Voltage. Select from 208V, 230V, or 240V, and press the Write key.
If the command has been accepted, the word “Successful” will appear at the bottom left side of the
display.
1. Repeat the process in step 1 in selecting the Rated Output Voltage.
2. Use the keypad to type in the current date in the format: Mon 10/05/2009 and press Write.
3. Use the keypad to type in the current time in 12 hour format: 12:15 PM and press Write.
4. The Main screen is now displayed. Verify the UPS is in BYPASS mode. The mode (lower right side
of the display) should display Bypass. If it does not display Bypass, press and momentarily hold
the STOP button on the Main display.
5. With the UPS in bypass mode, cycle power to the UPS as follows:
•At the rear of the UPS switch the main circuit breaker MCCB to OFF.
•Leave the UPS off until the DC bus is safely discharged (approximately 5-10 minutes).
•Restart the UPS by switching the main circuit breaker ON.
