1.0 Product Description
1.1 Theory of Operation
An Uninterruptible Power Supply (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 fluctuations and interruptions.
During normal operation the UPS utilizes commercial AC power and removes high voltage
spikes and transients caused by switching and faults on the main utility. 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. 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.
When AC input power becomes available again, operation returns to normal. The UPS
batteries begin to recharge, so they will be ready for the next power interruption.
1.2 Application and use
Toshiba's 4200 Series of on-line, Uninterruptible power systems (UPS) provide continuous
computer grade AC power in a compact, efficient, high performance unit. The UPS assures
safe, reliable operation of critical office equipment, ranging from personal computers to mini-
computers to local area networks (LAN). All units feature an audible alarm that sounds if the
battery voltage drops below standard during use. This is an additional aid to help in retaining
the valuable office data banks, and all units allow for computer interfacing.
1.3 Power Backup
During an electrical power failure the UPS unit's batteries automatically supply DC power to the
inverter that supports the load equipment, without interruption. For example, when used to
support a computer, the UPS’s back-up assures additional time to complete your activity and
store data after a power failure occurs.
1.4 Power Conditioning
While commercial power is present, the UPS supplies conditioned power to the load while
maintaining its batteries in a charged condition. The UPS protects the connected load 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 it can cause equipment to operate erratically, or damage
software and hardware.

2.0 Uncrating/Inspection/Storage/Disposal
2.1 Uncrating the new UPS equipment:
Upon receipt of the UPS, a careful inspection for shipping damage should be made.
1) Remove the screws that attach the
shipping crate to the pallet; remove the
crate and foam packing material.
2) Unbolt the rails from both the unit and the shipping
pallet. Place the rails on the front of the pallet as
shown in figure 2.2 and figure 2.3. Use the four
1/2x3" bolts used to secure the rails to the shipping
pallet to attach the rails as shown to the front of the
pallet.
3) Place the tie brackets as shown in
figure 2.3 in the slots at the lower
end of the ramps. SLOWLY roll the
unit down the ramp.

TOSHIBA
10
2.2 Inspection of the new UPS equipment
After Uncrating:
1) Check the unit for loose, broken, bent or other damaged parts. If damage has occurred
during shipment, keep all original crating and packing materials for return to the shipping
agent. The equipment warranty will not apply to units that 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.
2.3 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) Charge the system's batteries.
2) Perform a complete system shutdown as described in section 6.12 of this
manual.
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.
4) If stored in an ambient temperature under 20° C (68° F); recharge the batteries
every 9 months.
5) If stored in an ambient temperature of 20° to 30° C (68° to 86° F); recharge the
batteries every 6 months.
6) If stored in an ambient temperature of 30° to 40° C (86° to 104° F); recharge the
batteries every 3 months.
2.4 Disposal
Please contact your state environmental agency for details on proper disposal of electrical
components and packaging in your particular area.
ATTENTION 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 batteries.

3.0 Precautions
Based on the 4200 Series UPS unit's external dimensions and the way the outer panels are
removed; minimum amounts of unobstructed space around the unit is necessary for ventilation
and maintenance access. Figure 3.1 shows the minimum clearances required for proper UPS
site installation.
3.1 Installation Precautions
1) Do not install the UPS on an inclined surface,
or areas that are subject to frequent vibrations
or jolting. This could damage UPS circuits.
2) Do not allow liquids or foreign objects to get
inside the UPS.
3) Allow at least 700 mm (28 in) on the front side
and 500 mm (20 in) on the rear and sides of
the UPS unit for air ventilation and
maintenance access.
4) Do not install the UPS in a location that is
subject to high humidity. Also, do not install
the unit in areas that are exposed to direct
sunlight, or contaminated areas subject to
high levels of airborne dust, metal particles, or
flammable gasses.
5) Verify the ventilation and air conditioning
system at the site is capable of removing the
heat generated by the UPS unit (see Section,
5.1 Specifications, "Environment").
Ambient temperature range for operating the UPS
is 0° to 40°C (32° ~ 104°F); 25°C (77°F) is the
recommended operating temperature for
maximum battery life.
6) Avoid installation near sources of electrical
noise. Always make sure that the unit's
ground is intact to prevent electrical shock
and help prevent electrical noise.
7) This UPS generates and radiates 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 in near proximity. If such
interference occurs, the UPS should either be
installed farther away from the affected
equipment and/or powered from a different
source than the affected equipment.

3.2 Pre-start Precautions
Before connecting the UPS to a power source; move the MCCB switch (ON/OFF), on the side
panel, to the OFF position and move the operation STOP/RUN key switch, on the front panel
(See Section 9 for location), to the STOP position.
3.3 Operating Precautions
1) The UPS should not be powered up until the entire operation manual has been reviewed,
and understood.
2) The input power source voltage must be within +10% to -15% of the rated input voltage.
The input frequency must be within the rated input frequency range. Voltages and
frequencies outside of the permissible 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.
