1.0 Product Description

1.1 Theory of Operation

An Uninterruptible Power System (UPS) is a system t hat is installed between the commerci al power and the load equi pment. The UPS provides steady AC output power duri ng c om m er ci al power fluctuations and interruptions.

During normal operation the UPS receives comm ercial AC power and removes any high voltage spik es and tr ansi ents caused by switching or faults on the main utility. The result of this process is maxim um power conditioning and regul ation of the power applied to the load.

If the AC power supplied t o the UPS dr ops bel ow a specif ied voltage level, the batteries of the UPS are automati c ally switc hed on and will supply power to the load. This insures that the loads connected to t he UPS c ontinue to receive power with no inter r uption. This power is provided for a peri od 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 becom es available again, normal system oper ation resumes and the UPS battery-char ge c y cl e r esumes.

1.2 Application and use

Toshiba's 4200FA Uninterruptible Power Systems (UPS) pr ov ide c ontinuous computer grade AC power in a compact and effi ci ent high-performance unit. The UPS assures safe, reliable operation of critical office equipment, ranging from personal c om puters to mini-computers to local area networks (LAN). All units feature an audible alarm that sounds if the batt er y v oltage drops below standard during use. This is an additional ai d to help in retaining the valuable office data banks, and all units allow for computer interfacing.

TOSHIBA

1.3 Power Backup

During an electri c al power failure the batteries of the UPS unit supply DC power to the inverter that supports the l oad equipment automatically , without interrupti on. For example, when used to support a computer , a UPS backup assures addi tional time to complete your activity and store data after a power f ailure occurs.

1.4 Power Conditioning

While commercial power i s present, the UPS supplies conditioned power to the load while maintaining the batteries in a charged condi tion. The UPS protects the connect ed load against the normal everyday pr oblems associated with heav y use of raw commerci al power, including power sags, surges, signal interference, and spi kes. This protection keeps power-l ine problems from reaching your load where i t can cause equipment to operate erratically, or damage software or hardware.

TOSHIBA

2.0 Unpacking/Inspection/Storage/Disposal

2.1 Unpacking the UPS Equipment

1) Upon receipt of t he UPS, a careful inspection for shipping damage should be made.

2) For units shipped in a c r ate, r em ov e the screws that at tach the shipping crat e panels to each other and to the pallet. Remove the crate and foam packing materi al.

3) Unbolt the unit fr om t he shi pping pallet.

4) Lift the UPS from the pallet usi ng a forklift that has suffici ent capacity. Approach the UPS only from the front or rear.

2.2 UPS Equipment Insp ection

ATTENTION

UPS Equipment Insp ection

Upon receipt of the UPS, a car eful inspection for shipping damage should be made. Use caution when rem ov ing unit from pallet. Refer to labels or docum entation attached to packing material.

After Uncrating

1) Check the unit for loose, brok en, bent or other damaged parts. If damage has occurred during shipment, keep all original crating and pac king materials for ret ur n to t he shipping agent. The equipment warranty will not apply to units that are damaged during shipment.

2) Check to see that the rat ed c apaci ty and the model number specifi ed on the nameplate conform to the order specif ications.

2.3 Storage of the UPS Equipment

If the UPS equipment is t o be subject to long or short-term storage, the f ol lowing guidelines should be used.

Avoid:

1) Storage in sites subject to extreme changes in temper ature or high humidity.

2) Storage in sites subject to exposure of high lev els of dust or metal par ticles.

3) Storage on incli ned floor surfaces or in sites subject to excessive vibration.

TOSHIBA

2.4 Disposal

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 Stopping the UPS in section 6.12).

3) Place the MCCB switch of t he UPS in the OFF positi on ( see section 4.1for location).

Storing:

1) Store within t he temper ature range of –20°C to 40°C (-4°F to 104°F).

2) For best results, stor e the UPS in the original shipping c ontainer and place on a wood or metal pallet.

3) The optimum storage temperature is 21°C (70°F). Higher am bient temperatures cause UPS bat teries to require rec harging more frequently.

After Storing:

1) If stored in an ambient temper ature less than 20°C (68°F); rec har ge the batteries every 9 months.

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

3) If stored in an ambient temper ature of 30°C to 40°C (86°F to 104°F); r ec har ge the batteries every 3 months.

environment al pr otection agencies in your ar ea, t he battery manufacturer , or call Toshiba toll-fr ee at ( 800) 231- 1412 for more information about recycling batteri es.

3.0 Precautions

Because of the exter nal dimensions of the 4200FA UPS and the way the outer panels are to be removed; onl y a minimum amount of space around the unit is requir ed for v entilation and maintenance access. Figure 3.1 shows the minimum clearanc es required for proper UPS installation.

3.1 Installation P recautions

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

2) Install the UPS in a well ventilated location with the required allowances for v entilation and servicing as shown in fi gur e 3.1.

3) Install the UPS where the ambient temperature is within the correct operating range ( see the UP S Specifications in section 5.1). Verify that the ventilation and air conditioni ng system at the site is capable of removing the heat gener ated by the UPS unit (see Section, 5.1 Specifications, "Environment " ). Ambient temperature r ange for operating the UPS is 0°C – 40°C (32°F – 104°F);

25°C (77°F) is the reco mmend ed operating temperature for maximum battery life.

4) Do not install the UPS in a locati on that is subject to high humi dity.

5) Do not allow the UPS to be exposed to direct sunli ght.

6) Do not install the UPS in areas that are subject to contamination such as high levels of air bor ne dust, metal particles, or flammable gasses.

7) Avoid install ation near sources of electric al noise and always ensure that the earth ground is intact to prevent electrical shock and help prevent electric al noise.

8) Do not install the UPS in an area t hat may expose the UPS to water or that may allow any foreign matter to get inside.

9) This UPS generat es and radiates radiofrequency energy dur ing operation. There is no guarantee that the UPS will not influence some sensitive devices that are operati ng cl ose by. If such interfer ence is experienced, the UPS should be installed farther away from the affected equi pment and/or powered from a different source than the affected equipment.

10) The user should prov ide output over current protection for hardwired UPS versions. See S afety Instructions on page 10 for the corr ect dev ic e r ating.

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 operati ng normally in the AC input mode. The conver ter of the UPS, including a boost chopper ci r c uit, converts the AC input power to DC power. The boost c hopper c ircuit maintains a constant voltage and provides current lim iting for battery chargi ng. It also supplies a DC voltage of the proper lev el to the inverter section. The inverter secti on generates a high quality sine wav e output voltage. The UPS batteries always maintai n a charge during normal UPS operation.

6.1.2 Bypass Mode

If the UPS detects an overload or develops an internal fault , power flow is automatic ally switched from the main ci r c uit of the UPS to the By pass ci r c uit. Power flow through the Bypass is shown in the following illustrati on. This changeover occurs automatically in less than 4 milliseconds. The s witching period is not long enough to cause interruptions to oc c ur in most loads. If the power flow is tr ansferred to the bypass circ uit because of an overload and the overload condition ends within a specifi ed peri od of time, normal operation wil l resume automati c ally (see Section 6.16 Overl oad Oper ation).

If the power flow is transferred to the bypass circui t due t o a fault c ondition, the power flow must be transfer r ed m anually from the Bypass circuit back to the i nv erter circuit after the fault is cleared ( see Section 6.11 Start-up Procedur e) .

6.1.3 Battery Backup Mod e

The following illustration shows power flow during the battery backup mode. In the event of an AC power failur e the batter ies of the UPS instantly begin supplying DC power to the UPS to the main inverter circuit. This circuit c onv ert s the DC power i nto AC power. The AC power is availabl e at t he output of t he unit. This back-up process will continue until the UPS battery voltage drops bel ow a specif ic minimum level. At which time the batteries cease supplyi ng power to the load.

This minimum level is the shutdown voltage minimum (V min). The rated battery voltage table on page 33 shows (V min). The bat tery backup time and discharge proces s i s explained in S ection 6.2.

6.2 Battery Backup Time and Disch arge Process

The UPS system, when used in conj unc tion with a Toshiba designed Battery System, is designed to provi de several minutes of back-up time for the 4200FA UPS (Refer to the Battery System M anual for back-up times). These times are valid for full-load oper ation. At half-load operat ion the batteries can provide approximately 2 times the specified value. The exact times will depend on the UPS model used, condition of the batt eri es, amount and type of load, temper ature, and other variables.

CAUTION

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

Contact your Toshiba sal es repres entative if using bat tery systems other than Toshi ba- desi gned battery systems to determine compliance. Using other systems may void the warranty and/or the saf ety certifications.

6.3 Battery Low Volt age Tolerances

Excessive discharge will cause the UPS batter y volt age to drop below tolerable levels. The table below list s 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 .

Nominal Voltage 288 VDC

Alarm Voltage 252 VDC

Shutdown Voltage min. 216 VDC

6.4 Battery Recharging

The illustration below shows the battery rec har ge pr oc ess af ter a full discharge.

TOSHIBA

The recharge process typically consists of three periods. During the fi r st 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 rec har ge time) while assuring safet y and long battery life.

In the second period, constant-voltage c ontrol starts and the current gr adually decreases as the batteries charge to the fully charged state.

In the third peri od, a t ri ckle current continues to fl ow into the batteries to maintai n the f ully charged status at the normal DC Voltage level.

A full recharge requires approximatel y 24 hours (90% rec har ge in 10 hours) after a complet e discharge.

The following table shows the rated maximum and minimum battery voltages, and the charge current for each of the sizes for 75°C operati on.

6.6 EPO (Emergency Power Off) Functi on

The 4200FA UPS system is equi pped with terminals for receiv ing an emergency power-off (EPO) closed contact switc h c ommand from two locations: (1) a rem ote loc ation (see Section 4.2 Terminal Block Details) and (2) fr om a fr ont panel mounted EPO switch (see Section 6.5 Front P anel Lay out).

This safety f eature enables quick shutdown of the UPS AC output and bat tery circuits. Typically the em er genc y 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 equi pm ent 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 t he UP S unit is in the AC input mode (see Section 6.1.1), battery backup mode ( see Sec tion 6.1.3), or the circuit bypass mode (see Section 6.1.2). See EMERGENCY OFF screen in Secti on 6.12 Shutdown Procedure. T he following figure shows the UPS condition after applicati on of t he EPO switch. Use the Start-up Procedure (see Section 6.11) for rest ar ting the unit.

The following is a li st of t he user-notification LEDs and their function. On when the UPS is not in an input over-voltage condition, input under-voltage condition, or

power failure state. If there is an input power failure this LED is off. If there is no power failure and the input voltage is in an over-volt age c ondition, the AC IN LED will flicker on and off rapidly (0.4 sec on and 0.4 sec off). If there is no power failure and the input voltage is in an under-voltage c ondition the AC IN LED will be off.

On when the UPS inverter is operat ing.

On when the UPS is in the static bypass mode.

On when the UPS is in the batter y-discharge mode. If the battery is l ow duri ng a batt er y discharge, the B ATT lamp will flicker on and off slowly ( 1.2 second on and 1.2 second of f). The BATT LED will go off if the battery voltage reaches the shutdown level during the battery-discharge mode.

8.0 Preventive and Scheduled Maintenance / Part Replacement

8.1 Preventive Maintenance

Toshiba's 4200FA Uninterr uptible Power Systems have been designed to provide years of trouble-f ree operation requiri ng a minimum of preventive maintenance.

The best preventive measure that the UPS user can take is to keep the ar ea ar ound the unit, particular ly the air inlet vents, clean and fr ee of moistur e and dust ac c um ulations. If the atmosphere of the installation site is ver y dusty, use a vacuum cleaner to periodicall y remove dust accumulations from the system. Schedul e authorized Toshiba servi c e cent er s to perform internal parts inspections annually.

Before performing any maintenance the technician should be

CAUTION

8.2 Parts Replacement

The following list shows intervals for periodic maintenance and replac em ent of certain UPS parts.

familiar with and follow the important safety instructions located on page 10.

Proper maintenance of the battery system of this unit by a qualified service technician is essential to the saf ety and r eliability of your UPS system. Refer to servic e m anual.

1) Batteries: VRLA batt eri es are maintenance free with r espect to electrolyte only. The charging v oltage, temperature, performance and connection resistance must be m onitored 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 shoul d be once every 3 to 5 years as a minimum. All of the batteries must be replaced at the same time.

Quarterly M aintenance A. Visual Checks

1) Leakage.

2) Corrosion on positive terminal. B. Chec k battery temperatur e at t he negative terminal. C. Measure and record the system float charging volt age. D. Measure and record the float charging voltage of eac h unit.

Semi-Annual Mai ntenance A. Repeat the quarterly c hec k s. B. P erform a 10-second high rate (e.g., 100 A) load test on the individual

batteries. C. Test for the purpose of trending the battery over time (optional). D. Re-torque all battery connecting hardware (if applicable). E. P erform battery connector resistance checks.

2) Aluminum electrolytic capacitors: Replac e onc e ev ery 5 years.

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

4) Cooling fan: Replace once every 3 years.
