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

Toshiba's 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.

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.

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.

TOSHIBA

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.

2.4 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 5.18

of this manual.

Storing:

1) Store within a temperature range of - 4° to 104° F (-20° to 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.

4) If stored in an ambient temperature under 68° F (20° C), recharge the batteries every 9 months.

5) If stored in an ambient temperature of 68° to 86° F (20° to 30° C), recharge the batteries every 6 months.

6) If stored in an ambient temperature of 86° to 104° F (30° to 40° C), recharge the batteries every 3 months.

2.5 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 (800) 231-1412 for more information about recycling batteries.

3.0 Installation Precautions

Based on the 4200FA UPS external dimensions and the way the outer panels are removed; minimum amounts of unobstructed space around the unit are necessary for ventilation and maintenance access. Figure 3.1 shows the minimum clearances required for proper UPS site installation.

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 20” (500 mm) on the front side and 6" (152 mm) 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.

Ambient temperature range for operating the UPS is 32° – 104°F (0° – 40°C); 77°F (25°C) 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 radiofrequency 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.

Before connecting the UPS to a power source; move the Circuit Breakers (ON/OFF), on the front panel, to the OFF position and move the operation STOP/RUN key switch, on the front panel, to the STOP position.

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% (to start UPS) 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.

5.7 Operating the UPS

5.7.1 AC Input Mode (Normal Operation)

The following illustration shows circuit power flow when the UPS is operating normally in the

AC Input Mode. The rectifier includes a boost chopper circuit that converts the AC input power into DC power. The boost chopper circuit maintains a constant voltage with current limiting abilities for charging the batteries. The rectifier 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.”

Power flow in AC Input 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").

5.7.3 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).

5.8 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.

CAUTION

Contact Toshiba when using other than Toshiba designed Battery Systems to determine proper compliance. Using other systems could void Warranty and or

Safety Certifications.

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

5.9 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.

TOSHIBA

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 15/25/30/33kVA and approximately 11.5 amperes for the 50 kVA. 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 hours) 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.

5.12 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-

7.0 Authorized Factory Service

7.1 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 Maintenance Bypass: This verifies the operation of the Maintenance Bypass.

Toshiba's 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 Toshiba service centers to perform internal parts inspections annually.

CAUTION

Before performing any maintenance the technician should be familiar with and follow the important safety instructions within this manual.

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. Refer to service manual.

TOSHIBA

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.

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.

Semi-Annual maintenance

A. Repeat the quarterly checks.

B. Perform a 10-second high rate (e.g. 100 amp) load test 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).
