12 1600EP Series Instruction Manual
Product Description
An uninterruptible power system is a system that is installed between the commercial power and the load
equipment. The UPS provides steadyAC output power during commercial power short-term blackouts or
brownouts. 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 commercialAC 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 commercialAC power. The UPS converts it all to flat 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.
IftheACpower supplied to the UPSdropsbelowaspecifiedvoltagelevel, the unit’sbatteriesautomatically
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 1600EP Series of on-line uninterruptible power system (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 1600EP Series (208/240V) offers UPS models with the following capacities:
MODEL Output Capacity @ 240V Output kW @ .85PF 240V
UE3G2L036C61T 3.6 kVA 3.1 kW
UE3G2L060C61T 6 kVA 5.1 kW
UE3G2L080C61T 8 kVA 6.8 kW
UE3G2L100C61T 10 kVA 8.5 kW
UE3G2L140C61T 14 kVA 11.9 kW
UE3G2L180C61T 18 kVA 15.3 kW
UE3G2L220C61T 22 kVA 18.6 kW
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.
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 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.

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 operating systems (OS), which can automatically
implement the shutdown function and restart the operation:
Applicable OS: Windows NT, IBM OS/2 LAN server, LANtastic
When the power fails, the OS detects the power failure signal from the UPS and starts the shutdown
process.
At the end of the shutdown process, the OS sends 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 sent to the UPS ten 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.
