Product Description

An uninterruptible power system is a system that is installed between the commercial power and the load equipment. The UPS provides steady AC output power during commercial power short-term blackouts or brownouts. 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.

During normal operation, the UPS uses commercial AC power . In addition, it takes in all of the high voltage spikes and transients caused by switching and faults, and all of the common-mode and normal mode noise which is associated with commercial AC power. The UPS converts it all to ﬂ at DC power. From this power, the UPS charges its batteries and generates its own extremely high quality AC waveform output. The result of this process is maximum power conditioning and regulation.

If the AC power supplied to the UPS drops below a speciﬁ ed 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. When AC input power becomes available again, operation returns to normal. The unit’s batteries begin to recharge so they will be ready for the next power interruption.

Application and Use Toshiba’s 1600EP Series of on-line uninterruptible power system (UPS) systems provide continuous

computer-grade AC power in a compact, high performance, and energy efﬁ cient unit. The UPS unit assures safe and reliable operation of critical ofﬁ ce equipment. This can range from word processors and personal computers to mini-computers and local area networks. All units feature an audible alarm which sounds if the battery voltage drops below standard during use. This is an additional aid to help in retaining the valuable ofﬁ ce data banks. All units allow for computer interfacing.

Output Rating

Toshiba’s 1600EP Series (208/240V) offers UPS models with the following capacities:

MODEL Output Capacity @ 240V Output kW @ .85PF 240V

UE3G2L036C61T 3.6 kVA 3.1 kW UE3G2L060C61T 6 kVA 5.1 kW UE3G2L080C61T 8 kVA 6.8 kW UE3G2L100C61T 10 kVA 8.5 kW UE3G2L140C61T 14 kVA 11.9 kW UE3G2L180C61T 18 kVA 15.3 kW UE3G2L220C61T 22 kVA 18.6 kW

Power Backup

When an electrical power failure occurs, the UPS’s internal batteries automatically supply back-up power to the load without interruption. For example, when used to support a computer, the UPS back-up assures enough additional time to complete the activity and store the data. This allows an orderly shutdown after a power failure has occurred.

Power Conditioning When commercial power is present, the UPS supplies conditioned power to the load while maintaining its

batteries in a charged condition. The UPS protects 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 they can cause equipment to operate erratically, or damage software and hardware.

Inspection/ Storage/ Disposal

Inspection

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

Unpacking

Check the unit for loose, broken, bent or otherwise damaged parts. If damage has occurred during shipping, keep all original crating and packing materials for return to the shipping agent. The warranty does not apply to damage incurred during shipping. Ensure that the rated capacity and the model number speciﬁ ed on the nameplate conform to the order speciﬁ cations.

Storage

During periods of non-use, the following guidelines are recommended for storage.

Storage Preparation

1 Power up the UPS and allow it to operate with no load for 24 hours to fully charge the

batteries. 2 Stop the unit (see “Stop Operation” on page 29). 3 Place the MCCB switch (see page 52 for location) in the “Off” position.

Storing Conditions

• For best results, store the UPS in the original shipping container and place on a wood or

metal pallet.

• Storage temperature: -20 to 40 °C (-4 to 104 °F).

• The optimum storage temperature is 21 °C (70 °F). A higher ambient temperature will

require recharging more frequently during storage. Avoid the following storage locations:

• Locations that are subject to extreme temperature changes or high humidity.

• Locations that are subject to high levels of dust or metal particles.

• Locations that are subject to excessive vibration.

• Inclined ﬂ oor surfaces.

Storage Maintenance

• If stored at an ambient temperature less than 20 °C (68 °F), recharge the batteries every

9 months.

• If stored at an ambient temperature of 20 – 30 °C (68 – 86 °F), recharge the batteries

every 6 months.

• If stored at an ambient temperature of 30 – 40 °C (86 – 104 °F), recharge the batteries

every 3 months.

Installation Precautions

CAUTION

1 Install the unit in a well-ventilated location; allow at least 10 cm (4 inches) on all sides for air

ventilation and for maintenance. 2 Install the unit in a stable, level and upright position that is free of excessive vibration. 3 Install the unit where the ambient temperature is within the range speciﬁ ed on pages 21 and 24. 4 DO NOT install the UPS in areas that are subject to high humidity. 5 DO NOT install the UPS in areas that allow exposure to direct sunlight. 6 DO NOT install the UPS in areas that allow exposure to high levels of airborne dust, metal particles,

or ﬂ ammable gases. 7 DO NOT install the UPS in areas near sources of electrical noise. Ensuring a proper earth ground

will reduce the effects of electrical noise and will reduce the potential for electrical shock. 8 DO NOT install the UPS in areas that would allow ﬂ uids or any foreign object to get inside the UPS. 9 The UPS generates and can radiate radio-frequency energy during operation. Although RFI noise

ﬁ lters are installed inside of the unit, there is no guarantee that the UPS will not inﬂ uence some

sensitive devices that are operating near by. If such interference is experienced, the UPS should be

installed farther away from the affected equipment and/or powered from a different source than that

of the affected equipment. 10 The user should provide output over-current protection for hardwired UPS systems. See the section

titled Speciﬁ cations on page 20 and 23 for the device rating. 11 After ensuring that all power sources are turned off and isolated in accordance with established

lockout/tagout procedures, connect the power source wiring of the correct voltage to the input

terminals of the UPS. 12 Connect the output terminals of the UPS to the load (refer to NEC Article 300 – Wiring Methods and

Article 310 – Conductors For General Wiring). Size the branch circuit conductors in accordance with

NEC Table 310.16.

Conductor Routing and Grounding

1 Use separate metal conduits for routing the input power, output power, and control circuits. 2 Follow the wire size and tightening torque speciﬁ cations listed on page 16. 3 Always ground the unit to reduce the potential for electrical shock and to help reduce electrical noise. 4 A separate ground cable should be run inside the conduit with the input power, output power, and

control circuits.

THE METAL OF CONDUIT IS NOT AN ACCEPTABLE GROUND.

WARNING

1600EP Series Instruction Manual

Operating Precautions

1 The UPS should not be powered up until the entire operation manual has been read. 2 The voltage of the input power source must be within the range of +10% to -30% 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 activate the internal protection devices.

3 The UPS should not be used with a load that has a rated input that is greater than the rated output of

the UPS.

4 DO NOT use the UPS to provide power to motors that require high starting current or with motors that

require a long starting time, such as vacuum cleaners and machine tools (over sizing the UPS for lock

rotor current would be required). 5 DO NOT insert metal objects or combustible materials in the ventilation slots of the UPS. 6 DO NOT place, hang, or paste any objects on the exterior surfaces of the UPS. 7 The capacitors of the UPS maintain a residual charge for a while after turning the UPS off. The

required discharge time for each UPS typeform is provided via a cabinet label and a CHARGE LED.

Wait for at least the minimum time indicated on the label and ensure that the CHARGE LED has gone

out before opening the door of the UPS once the UPS power has been turned off. 8 DO NOT attempt to disassemble, modify, or repair the UPS. Call your Toshiba sales representative

for repair information. 9 Turn the power on only after attaching ALL of the covers.

10 DO NOT remove any covers of the UPS when the power is on. 11 If the UPS should emit smoke or an unusual odor or sound, turn the power off immediately. 12 The heat sink and other components may become extremely hot to the touch. Allow the unit to cool

before coming in contact with these items.

13 Warning signs should be placed on or near the load as a notiﬁ cation that the load is being powered

by the UPS.

14 Additional warnings and notiﬁ cations shall be posted at the equipment installation location as deemed

required by Qualiﬁ ed Personnel.

WARNING

CAUTION

1600EP Series Instruction Manual

While operating in the inverter mode, placing the breaker in the OFF position will switch the UPS to the battery backup mode. The output of the UPS will continue uninterrupted to the load. The unit must be in the bypass mode at the time that the breaker is placed in the OFF position for the UPS to shutdown power to the load.

After an Emergency Power Off ( EPO), do not reset the breaker until the UPS has been fully discharged. The UPS could be damaged if the unit is not fully discharged before the breaker is reset.

UPS Stop Signal Operation

When the UPS stop signal is sent to the UPS through pin 2 and 3 of the external contact interface, it is possible to automatically reset the following operating systems (OS), which can automatically implement the shutdown function and restart the operation:

Applicable OS: Windows NT, IBM OS/2 LAN server, LANtastic

When the power fails, the OS detects the power failure signal from the UPS and starts the shutdown process.

At the end of the shutdown process, the OS sends a stop signal to the UPS, and the UPS stops. When the power recovers, the UPS automatically starts output and restarts the OS. Even when the

power recovers while in a shutdown process, the UPS temporarily cuts off the output (10 - 20 seconds) and then restarts the OS within 10 minutes after the recovery from power failure. In this case the UPS cuts off output even with normal input power. Connect the UPS stop signal of the external contact interface only for the automatic processing so that the UPS output will not be cut off by mistake. If a stop signal is sent to the UPS ten minutes or more after the recovery from a power failure, then the UPS ignores this signal and continues to output power.

If the computer is started/restarted within 10 minutes after the recovery from a power failure, the power supply may be reset while the computer is restarting.

Operating the UPS

Battery Backup Time and Discharge Process

The UPS batteries provide about 5-7 minutes of back-up time depending on the 1600EP unit kVA rating. These times are valid when the unit is operating under full load and at the rated power factor. 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. See battery backup time in ‘Standard Speciﬁ cations’ beginning on

pages 20-25.

Starting the UPS

Turn the main circuit breaker (MCCB) on the back of the UPS (see pages 52-53) to the “ON” position (the breaker should normally remain in the “on” position).

Check that the AC INPUT LED on the front panel (see page 32 and 33) lights ‘green’. All LED’s on the front panel may light for a moment when the input breaker is turned “on”. This is normal. The UPS will now be supplying power in the bypass mode.

CAUTION

When running the UPS for the ﬁ rst time or after the power failure backup operation, charge the batteries for at least 24 hours (input breaker “on”) before operating the connecting load.

Using the UPS without charging the battery shortens the battery backup operation time, which could result in the destruction of data in case of a power failure.

Press RUN key to begin UPS operation (see page 34 for startup screens).

CAUTION

If the input breaker is turned off while UPS is in the bypass state, the output power stops. Any load devices will lose power.

Ensure that all sensitive loads have been previously shut down.

Stopping the UPS To stop the UPS, press the STOP key approximately 1 second until the LED changes from green to

“off”. The UPS is now in the bypass mode. To completely stop the UPS, turn the input breaker at the back of the UPS to the “OFF” position.

The recharge process usually consists of three periods. During the ﬁ rst period, the current is maintained at approximately 1 ampere. This current limit 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 period, constant-voltage control starts and current gradually decreases as the batteries charge to their normal fully charged state. In the third period, a slight “trickle” current continues to ﬂ ow into the batteries to keep them fully charged and “ﬂ oating” at the normal Vdc level. A full recharge usually requires 24 hours (90% recharge in 12 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.

Online Mode

AC Input Mode (Run operation)

The following illustration shows circuit power ﬂ ow when the UPS is operating normally in the AC input mode. The UPS rectiﬁ er, including a boost chopper circuit, converts AC input power to DC power. The boost chopper circuit maintains a constant voltage, with 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 unit’s batteries are always maintained in a constantly charged state when the UPS is in the run operation mode.

Static- Bypass Mode (Stop operation)

If the UPS unit is severely overloaded or develops an internal fault, power ﬂ ow is automatically switched from the unit’s main circuit to the bypass circuit. Power ﬂ ow through the bypass is shown in the following illustration. This change-over occurs automatically in less than 4 milliseconds in phase. The switching period is not long enough to cause interruptions to occur in most loads. If the power ﬂ ow is transferred to the bypass circuit because of an overload and that overload condition ends within a speciﬁ ed period of time then the power ﬂ ow will be transferred back to the AC input mode (run operation) automatically. If the power ﬂ ow is transferred to the bypass circuit due to an external fault the UPS will shut down power through the bypass to the load and indicate a system fault message. If the power ﬂ ow is transferred to the bypass circuit due to an internal fault the UPS will continue to supply power to the load through the bypass and indicate a system fault message (see system fault message DC-OC on page 48). If the power ﬂ ow is transferred to the bypass circuit due to an overload condition (see system warning message OL: REDUCE LOAD on page 44 and AUT O RETRANSFER on page 46), then the power ﬂ ow will automatically transfer from the UPS’s bypass circuit back to the inverter circuit after removing the overload if set to do so (see auto-transfer setting on page 40).

Battery Backup Mode (on batteries)

The following illustration shows power ﬂ ow during the battery backup mode. When commercial AC power failures occur, the UPS’ s batteries instantly begin supplying DC voltage to the UPS’s main inverter circuit. This circuit changes (inverts) the DC power into AC power. The AC power is available at the unit’ s output. This back-up process will continue until the UPS’s battery voltage drops below a speciﬁ c minimum level. When this occurs, the batteries will stop supplying power to the load. This minimum level is the rated minimum voltage (Vmin). The rated battery voltage chart on page 28 shows (Vmin). The battery backup time and discharge process is explained on page 28.

This safety feature enables quick shut-down of the UPS’s AC output and battery circuits. Usually 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 load 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

System Overview Screens

The System Overview Screens provide a summary of the current operational state of the UPS. Only one of the several possible overview screens is available at any moment. The current screen is automatically determined based upon the UPS state.

UPS Start-Up Screens Sequence

The Start-Up Screens consist of a series of automatically sequencing ‘System Overview Screens’. These screens notify operator of steps taken by UPS during its initialization. The sequence of Start-Up screens begins when AC input power is detected at UPS input.

If the correct AC input power is available and no abnormal operating conditions are present then the following system message will be displayed on the LCD screen.

Next, the LCD will report the current date and time. If necessary , the proper date and time can be set from the ‘Data Settings Screens’ (see pages 38 and 41 for details). The date and time appear using the format depicted in the following example:

11/04/2001(WED)

15.:22:47

Next, the LCD will report the current UPS Operational Mode and the current percentage of the maximum UPS capacity being supplied. Initially, the UPS is in bypass mode, and the following screen will appear:

NOTE: If input voltage is removed while UPS is in the

Bypass Mode then the output stops.

1600EP Series Instruction Manual

Page 35

Only if the UPS is instructed to enter its online (normal) mode, will the UPS attempt transfer into such operation mode. To enter the normal mode, the “RUN” key is pressed or the “AUTO RUN” has been conﬁ gured to “YES” (AUTO RUN setup is described in the ‘Data Screen Settings’

actions on pages 38

- 43. If either condition exists, the following screen will appear:

Shortly after transfer into the UPS online (normal) mode, the UPS will automatically begin a battery test if the setting is enabled (see page 40). This test ensures a healthy battery system is available should it be necessary to support the load. During the test, the LCD reports the current battery voltage as a percent of its expected value at full charge. This ﬁ gure will drop throughout the test, as the battery voltage is intentionally lowered to test performance. The test lasts for about 10 seconds, during which the following screen appears:

Preventive Maintenance/Parts Replacement

Preventive Maintenance

Toshiba’s 1600EP Series of 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 around and from the unit.

CAUTION

Only a qualiﬁ ed Toshiba Representative should be allowed to perform any routine maintenance or service on this equipment other than those preventive maintenance details which are described directly above this caution.

Parts Replacement

The following list shows recommended intervals for periodic replacement of certain UPS parts:

1 Batteries: In order to maintain system reliability, the UPS batteries should be replaced on a

regular schedule. To ensure reliable operation, all of the batteries should be replaced at the same time. Use the following chart for replacement:

UPS BATTERY REPLACEMENT

BATT AMB TEMP AVERAGE LIFETIME (% REDUCED)

20-25° C (68-77°F) Approximately 5 yrs 0%

30° C (86°F) Approximately 3.5 yrs 30%

35° C (95°F) Approximately 2.5 yrs 50% 40° C (104°F) Approximately 1.8 yrs 66% 45° C (113°F) Approximately 1.25 yrs 75%

2 Aluminum electrolytic capacitors: Replace once every 5 years. 3 Fuses: Replace once every 7 years.

4 Cooling fan: When operated in an ambient temperature of 30° C (86°F) to 40° C (104°F),

replace every 3.5 years. When operated in an ambient temperature of less than 30° C (86°F) , replace every 5 years.
