1.0 Product Description

1.1 Theory of Operation

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 fluctuations and interruptions.

During normal operation the UPS receives commercial AC power and removes any high
voltage spikes and transients caused by switching or faults on the main utility. The result of this
process is maximum power conditioning and regulation of the power applied to the load.

If the AC power supplied to the UPS drops below a specified voltage level, the batteries of the
UPS are automatically switched on and will supply power to the load. This insures that the loads
connected to the UPS continue to receive power with no interruption. This power is provided for a
period long enough to ensure that the load can be shut down in an orderly fashion. This prevents
loss of data and possible damage to the hardware or software.

When AC input power becomes available again, normal system operation resumes and the
UPS battery-charge cycle resumes.

1.2 Application and use

The TOSHIBA 4200FA Uninterruptible Power Systems (UPS) provide continuous computer grade
AC power in a compact and 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 batteries of the UPS unit supply DC power to the inverter that
supports the load equipment automatically, without interruption. For example, when used to
support a computer, a UPS backup 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 the 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 or

hardware.

CAUTION

Do not attempt to move the unit by the sides. Only move the
unit with a forklift or pallet jack. Moving the unit by pushing on

the sides may result in damage to the unit or injury to personnel.

4200 FA User’s Manual 9

2.2 UPS Equipment Inspection UPS Equipment Inspection

Upon receipt of the UPS, a careful inspection for shipping damage should be made. Use
caution when removing unit from pallet. Refer to labels or documentation attached to packing
material.

After Unpacking

1) Check the unit for loose, broken, bent or other damaged parts. If damage has occurred
during shipment, keep all 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 the 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) Allow the UPS to be operated for 24 hours to ensure that the batteries are fully charged.

2) Stop the unit (see Shutdown Procedure in section 6.12).

3) Place the MCCB switch of the UPS in the OFF position (see section 4.1 for location).

Storing:

1) Store within the temperature range of -4 – 104 °F (-20 – 40 °C).

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 70 °F (21 °C). Higher ambient temperatures cause
UPS batteries to require recharging more frequently.

After Storing:

1) If stored in an ambient temperature less than 68 °F (20 °C); recharge the batteries every 9
months.

2) If stored in an ambient temperature of 68 – 86 °F (20 – 30 °C); recharge the batteries every
6 months.

3) If stored in an ambient temperature of 86 – 104 °F (30 – 40 °C); 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

Because of the external dimensions of the 4200FA UPS and the way the outer panels are to be
removed; only a minimum amount of space around the unit is required for ventilation and
maintenance access. Figure 3.1 shows the minimum clearances required for proper UPS
installation.

3.1 Installation Precautions

1) Install the UPS in a stable, level, and upright position that is free of vibration.

2) Install the UPS in a well ventilated location with the required allowances for ventilation
and servicing as shown in figure 3.1.

3) Install the UPS where the ambient
temperature is within the correct
operating range (see the UPS
Specifications in section 5). Verify that
the ventilation and air conditioning
system at the site is capable of
removing the heat generated by the
UPS unit (see Section, 5 Specifications,
"Environment"). Ambient temperature
range for operating the UPS is 32 –

104 °F (0 – 40 °C); 77 °F (25 °C) is the

6.0 Operating the UPS

6.1 Operating the UPS

6.1.1 AC Input Mode (normal operation)

The following illustration shows circuit power flow when the UPS is operating normally in the
AC input mode. The converter of the UPS, including a boost chopper circuit, converts the AC
input power to DC power. The boost chopper circuit maintains a constant voltage and provides
current limiting for battery charging. It also supplies a DC voltage of the proper level to the
inverter section. The inverter section generates a high quality sine wave output voltage. The
UPS batteries always maintain a charge during normal UPS operation.

Power Flow

Input

Power

Isolating

XFMR

6.1.2 Bypass Mode

If the UPS detects an overload or develops an internal fault, power flow is automatically
switched from the main circuit of the UPS to the Bypass circuit. Power flow through the
Bypass is shown in the following illustration. This changeover occurs automatically in less than
4 milliseconds. The switching period is not long enough to cause interruptions to occur in most
loads. If the power flow is transferred to the bypass circuit because of an overload and the
overload condition ends within a specified period of time, normal operation will resume
automatically (see Section 6.16 Overload Operation).

6.1.3 Battery Backup Mode

The following illustration shows power flow during the battery backup mode. In the event of an
AC power failure the batteries of the UPS instantly begin supplying DC power to the UPS to the
main inverter circuit. This circuit converts 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 battery
voltage drops below a specific minimum level. At which time the batteries cease supplying
power to the load.

This minimum level is the shutdown voltage minimum (V min). The rated battery voltage table
on page 36 shows (V min). The battery backup time and discharge process is explained in
Section 6.2.

6.2 Battery Backup Time and Discharge Process

The UPS system, when used in conjunction with a TOSHIBA designed Battery System, is

designed to provide several minutes of back-up time for the 4200FA UPS (Refer to the Battery

System Manual for back-up times). These times are valid for full-load operation. At half-load
operation the batteries can provide approximately 2 times the specified value. The exact times
will depend on the UPS model used, condition of the batteries, amount and type of load,
temperature, and other variables.

CAUTION

The following illustration shows the battery discharge process at full load conditions.

6.3 Battery Low Voltage Tolerances

Excessive discharge will cause the UPS battery voltage to drop below tolerable levels. The table
below lists the normal operating voltage, the voltage levels at which the low-voltage alarm will
sound, and the low-voltage level at which an automatic shut down will occur.

Shutdown Voltage min. 216 VDC

Contact your TOSHIBA sales representative if using battery systems
other than TOSHIBA designed battery systems to determine
compliance. Using other systems may void the warranty and/or the

safety certifications.

Nominal Voltage 288 VDC

Alarm Voltage 252 VDC

4200 FA User’s Manual 31

6.4 Battery Recharging

The illustration below shows the battery recharge process after a full discharge.

The recharge process typically consists of three periods. During the first period, the charging
current is maintained at approximately 20.0 amperes. This current is the maximum value that
can be used to charge the batteries (for minimal recharge time) while assuring safety and long
battery life.

TOSHIBA

In the second period, constant-voltage control starts and the current gradually decreases as
the batteries charge to the fully charged state.

In the third period, a trickle current continues to flow into the batteries to maintain the fully
charged status at the normal DC Voltage level.

A full recharge requires approximately 24 hours (90% recharge in 10 X discharge time) after a
complete discharge.

The following table shows the rated maximum and minimum battery voltages, and the charge
current for each of the sizes for 75 °F (24 °C) operation.

6.6 EPO (Emergency Power Off) Function

The 4200FA UPS system is equipped with terminals for receiving an emergency power-off
(EPO) closed contact switch command from two locations: (1) a remote location (see Section

4.2 Terminal Block Details) and (2) from a front panel mounted EPO switch (see Section 6.5
Front Panel Layout).

This safety feature enables quick shutdown of the UPS AC output and battery circuits. Typically
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 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 the AC input mode (see Section

6.1.1), battery backup mode (see Section 6.1.3), or the circuit bypass mode (see Section 6.1.2).
See EMERGENCY OFF screen in Section 6.12 Shutdown Procedure. The following figure

shows the UPS condition after application of the EPO switch. Use the Start-up Procedure (see

Section 6.11) for restarting the unit.

8.0 Preventive and Scheduled Maintenance / Part Replacement

8.1 Preventive Maintenance

TOSHIBA 4200FA 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. Schedule authorized factory service representatives to
perform internal parts inspections semi-annually.

CAUTION

CAUTION

8.2 Parts Replacement

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

1) Batteries: Valve Regulated Lead Acid (VRLA) batteries are maintenance free with
respect to electrolyte only. The charging voltage, temperature, performance and
connection resistance must be monitored periodically. Necessary corrective actions
must be made in order to assure safe reliable power is supplied by the UPS. The
aforementioned items affect the life of batteries, so replacement should be once every
3 to 5 years as a minimum. All of the batteries must be replaced at the same time.

Recommended Quarterly Maintenance

A. Visual Checks

B. Check battery temperature at the negative terminal.
C. Measure and record the system float charging voltage.
D. Measure and record the float charging voltage of each unit.

Recommended Semi-Annual Maintenance

A. Repeat the quarterly checks.
B. Perform impedance checks on the individual batteries.
C. Test for the purpose of trending the battery over time.
D. Re-torque all battery connecting hardware (if applicable).

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

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

4) Cooling fan: Replace once every 3 years.

Only factory trained representatives should perform repairs or
maintenance on the UPS..

Proper maintenance of the battery system of this unit by a qualified
service technician is essential to the safety and reliability of your UPS

system. Refer to the battery service manual.

1) Leakage.

2) Corrosion on positive terminal.
