1.0 Inspection/Storage
1.1 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.
1.2 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.
TOSHIBA
Before storing:
1) Charge the units batteries.
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
wood or metal pallet.
3) The optimum storage temperature is 21 deg C (70 deg F). Higher ambient
temperatures cause UPS batteries to need recharging more frequently.
After storing:
1) If stored in an ambient temperature under 20 deg C (68 deg F); recharge the
batteries every 9 months.
2) If stored in an ambient temperature of 20 to 30 deg C (68 to 86 deg F);
recharge the batteries every 6 months.
3) If stored in an ambient temperature of 30 to 40 deg C (86 to 104 deg F);
recharge the batteries every 3 months.

between 0 to 40 deg C (32 to 104 deg F).
high levels of airborne dust, metal particles, or inflammable gas.
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) 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 effected equipment and/or powered from a different source than
that of the affected equipment.
2.2 Prestart Precautions
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) 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.
5) Do not insert metal objects or combustible materials in the unit's ventilation slots.

3.0 Product Description
3.1 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.
TOSHIBA
3.2 Application and Use
Toshiba's 1400 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 minicomputers 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
and an external battery pack option (see specifications).
3.3 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.
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
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.
