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 critical load. 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 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 without 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 the AC input power becomes available again, the operation returns to normal and  
the batteries begin to recharge for the next power interruption.  
1.2  
Application and Use  
The TOSHIBA 4200FA On-Line, Uninterruptible Power Systems (UPS) provide continuous  
computer grade isolated 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 the standard during use. This is an  
additional aid to help in retaining valuable data and equipment. All units are capable of  
interfacing to a computer network.  
1.3  
1.4  
Power Backup  
During an electrical power failure the UPS 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,  
store data and initiate an orderly shutdown after a power failure occurs.  
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. In addition, the  
models with transformers provide total isolation to reduce the common and normal mode  
noises. This adds further protection to keep power-line problems from reaching your load,  
where it can cause equipment to operate erratically, or damage hardware and software.

Inspection of the new UPS equipment  
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.  
2.4  
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 6.15 of this manual.  
Storing:  
1) Store within a 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 need recharging more frequently.

13) Additional warnings and notifications shall be posted at the equipment installation location as  
deemed required by Qualified Personnel.  
When the UPS is in the Inverter mode, turning the breaker to the OFF  
position will cause the unit to go into the battery backup mode. The  
UPS will continue to provide power to the load. The unit must be in Bypass mode and then  
the breaker turned to the OFF position for the UPS to shut down power to the load.  
CAUTION  
Do not EPO (Emergency Power OFF) the UPS and then reset the  
breaker until the UPS has been fully discharged. The UPS could be  
damaged if the unit is not fully powered down before the breaker is  
reset.

4.5.3 UPS Shutdown (via RS-232C)  
When the UPS is operating from its internal batteries, a 'shutdown' order can be sent to the  
UPS instructing it to turn OFF after a user-specified amount of time. This function can  
allow you to stop discharging the UPS batteries after an orderly system shutdown has  
been completed. The UPS can be programmed to turn OFF up to 8 minutes after the  
'shutdown' command is given. This command can be cancelled before the specified time  
has elapsed by following the directions listed on the RS-232C screen.

6.0 Operating the UPS  
6.1  
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 into  
DC power. The boost chopper circuit maintains a constant voltage and provides current limiting for  
charging the batteries. 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 batteries are maintained in a  
constantly charged state when the UPS is in the “Normal Operation Mode.”

TOSHIBA  
6.2  
Bypass Mode  
If the UPS unit is severely overloaded or develops an internal fault, power flow is automatically  
switched from the main circuit to the Bypass circuit. Power flow through the bypass is shown in the  
following illustration. This changeover occurs automatically in less than 4 milliseconds in phase  
(Make-Before-Break). If the power flow is transferred to the Bypass circuit because of an overload  
and that overload condition ends within a specified period of time, then the power flow will "re-  
transfer" to the AC Input Mode (Normal Operation) automatically. If the power flow is transferred to  
the Bypass circuit due to a fault condition, then the power flow must be transferred manually  
from the UPS's Bypass circuit back to the Inverter circuit after repairing the fault (see "Start-up  
Procedure"). If the power flow is transferred to the Bypass circuit due to an overload condition,  
then the power flow will automatically transfer from the UPS's Bypass circuit back to the  
Inverter circuit after removing the overload (see "Overload Operation").

Battery Backup Mode  
The following illustration shows power flow during the battery backup mode. When  
commercial AC power failures occur, the batteries instantly begin supplying DC voltage to  
the main inverter circuit. This circuit inverts (hence; Inverter) the DC power into AC power.  
The AC power is available at the output. This back-up process will continue until the  
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 (V min).

6.5  
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 (Refer to the Battery System Manual  
for back-up times). These times are valid when the unit is operating under full load. When  
these models are operating at half load, the batteries can provide approximately 2 times  
the specified value. The exact length of these times will depend on the UPS model used,  
condition of the batteries, amount and type of load, temperature and other variables.  
Contact TOSHIBA when using other than TOSHIBA designed Battery Systems  
to determine proper compliance. Using other systems could void Warranty and  
or Safety Certifications.  
CAUTION  
The following illustration graphically shows the battery discharge process at full load  
conditions.  
6.6  
Battery Low Voltage Tolerances  
Excessive discharge will cause the UPS battery voltage to drop bellow tolerable levels. The  
chart shown below lists the voltage level at which each UPS unit's low-voltage alarm will  
sound, and also at what level the low-voltage condition will cause the unit to automatically  
shut down.

Battery Recharging  
The illustration below shows a graphical representation of the UPS battery recharge  
process after a full discharge.  
The recharge process usually consists of three steps. During the first step, the charging  
current is maintained at approximately 4.0 amperes for the 15/25/30 kVA with internal  
batteries, 10.0 amperes for the 15/25/30 kVA with internal transformer and approximately  
11.5 amperes for all 50 kVA models. 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. In the second step, constant-voltage control starts and current gradually decreases as  
the batteries charge to their normal fully charged state. In the third step, a slight "trickle"  
current continues to flow into the batteries to keep them fully charged and "floating" at the  
normal DC Voltage level. A full recharge usually requires approximately 24-72 hours (90%  
recharge in 10 X discharge time) after a complete discharge.  
The following chart shows the rated maximum and minimum battery voltages, and the  
charge current for each of the sizes while the unit is maintained in a 75 °F (24 °C) ambient.

EPO (Emergency Power Off) Function  
These units are equipped with terminals for receiving an EPO (Emergency Power Off)  
"closed contact" switch command from two locations: (1) a remote location and (2) from a  
front panel mounted EPO switch. This safety feature enables quick shutdown of the UPS  
AC output and battery circuits. Usually the EPO switch is installed in a central location that  
is easily accessible to personnel concerned with the operation of the UPS 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 is in the AC Input Mode, Battery Backup Mode, or the Bypass Mode. See  
'EMERGENCY OFF' screen. The following figure shows the UPS condition after  
application of the EPO switch. Use the Start-up Procedure for restarting the unit.

8.0 Start-up/Scheduled Maintenance/Part Replacement  
8.1  
Start-up  
The startup of the UPS equipment is broken up in several steps. These steps are as  
follows:  
1. Initial Condition: This is where the service technician checks the unit for physical  
damage and verifies the installation of the UPS (electrically).  
2. Static Checks: This step verifies the proper settings within the UPS logic.  
3. Wiring Check: The wiring to (power cables) and from (control wires) the battery  
cabinet.  
4. Main Voltage Check: The input voltages are checked to verify they are within the  
range.  
5. Energizing the UPS: This step begins the internal self-checks within the processor  
logic.  
6. Output Voltage Check: The output voltages are checked to verify they are within  
range.  
7. EPO (Emergency Power Off): The EPO is operated to verify its operation in case  
of an emergency.  
8. Load Testing: Performed if load is available.  
9. Generator Testing: Performed if Generator is available.  
10. Internal/External Maintenance Bypass: This verifies the proper operation of the  
Maintenance Bypass.  
8.2  
Preventive Maintenance  
The TOSHIBA 4200FA Uninterruptible Power Systems have been designed to provide no  
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.  
Schedule authorized TOSHIBA service centers to perform an internal parts inspection  
semi-annually.  
Before performing any maintenance the technician should be familiar  
with and follow the important safety instructions within this manual.  
CAUTION  
WARNING  
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.  
Schedule authorized TOSHIBA service centers to perform internal parts  
inspections semi-annually.

8.3  
Parts Replacement  
The following list shows intervals for periodic maintenance and replacement of certain UPS  
parts.  
1) Batteries: VRLA (Valve Regulated Lead Acid) batteries do not require the adding  
of water or electrolyte. The charging voltage, temperature, performance and  
connection resistance must be monitored periodically. Necessary corrective  
maintenance must be made in order to assure the UPS supplies safe reliable  
power. These 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 to eliminate the possibility of multiple failures due to resistances of the  
batteries.  
8)  
9)  
Recommended Quarterly Maintenance  
A. Visual Checks  
1) Leakage  
2) Corrosion on positive terminal  
B. Check battery temperature at the negative terminal  
C. Measure and record the system float charging voltage.  
D. Measure and record the individual unit’s float charging voltage.  
Recommended Semi-Annual maintenance  
A. Repeat the quarterly checks.  
B. Perform impedance checks on the individual batteries.  
C. Optionally test for the purpose of trending the battery over time.  
D. Re-torque all inter-battery connecting hardware (if applicable).  
2) Aluminum electrolytic capacitors: Replace once every 5 years.  
3) Fuses: Replace once every 7 years.  
4) Cooling fan: Replace once every 3 years.
