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.

6) Do not place, hang, or paste any objects on the top or on the exterior surfaces
of the UPS.

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.

Power flow in AC input mode for 1500 and 2000 VA Models

Both of the above illustrations show 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.

= power flow

5-15R

The above illustrations show power flow 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 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 on page 5-6 (See Section 5.4
for battery backup time) shows (Vmin).

Power flow in circuit-bypass mode for 1500 and 2000 VA Models

If the UPS unit is 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 change­over occurs automatically in approximately 4 milliseconds. The switching period
is not long enough to cause interruptions to occur in most UPS equipment loads.

After repairing the cause of the inverter shutdown, the energy flow must be
transferred manually from the UPS's bypass circuit back to the inverter circuit.
This is done by toggling the ON/OFF switch (on the unit's front panel) first to
OFF and then back to ON. This action resets (clears) the fault.

Notes:

1) The UPS's RECT/CHOPPER and INVERTER, although separate electrical
circuits, are physically located on the same heat sink. This is applicable to all
models.

2) The two UPS rear panel output receptacles are supplied from the UPS inverter
section through separate 15A output fuses (applies to the 1500 and 2000 VA
model only). Thus, an overload on one of the receptacle sets can cause a loss
of power to it while the other receptacle set remains active. If all of the UPS
indicator lights appear normal and power is not available at one of the receptacle
sets, check the associated output fuse.

2.) INVERTER: This green LED lights when the inverter output voltage is normal.

3.) FAULT: This red LED lights when an overcurrent, overvoltage, overload, or
overheating problem is detected. Operation of the unit's inverter is inhibited until
the fault is corrected and the system is reset. Refer to Section 5.2 "System
Protection Features" for details.

5.4 Battery Backup Time

The UPS unit's batteries provide about 10 minutes of back-up time for the 500
through 1200 VA capacity units and about 8 minutes of back-up time for the
1500 through 2000 VA capacity units. These times are valid when the 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 and 4.2.

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 constant­voltage 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) for the 500 through 750 VA models and 30 hours (90% recharge in
8 hours) for the 800 through 2000 VA models.

7.0 Preventive Maintenance/Parts Replacement

7.1 Preventive Maintenance

Toshiba's 1400 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.

7.2 Parts Replacement

The following list shows recommended intervals for periodic replacement of certain
UPS parts.

1) Batteries: In order to maintain system reliability, the UPS unit's batteries
should be replaced once every 3 to 5 years. To ensure reliable operation, all
of the batteries should be replaced at the same time.

2) Aluminum electrolytic capacitors: Replace once every 5 years.

3) Fuses: Replace once every 7 years (see output fuse rating chart below).
