1. Introduction

This manual is designed to ensure the safe and correct operation of the TOSNIC-7000S Uninterruptible Power System (hereafter referred to as "UPS unit"). Please read the "Safety Precautions" and "Operation" sections of this manual carefully before use and make sure you have a thorough understanding of the information in these two sections. Keep the manual handy in a place near the unit so you can refer to it instantly when needed.

Note that this manual was written based on the standard circuits shown in figures 6.2 (page

13). The delivered UPS system may, if desired by the customer, differ from the standard configuration. Similarly, the displayed markings may differ from those on the standard system. If this is the case, follow the operating procedures and indications provided in the development circuit diagrams created individually for the UPS system actually delivered.

Also, while this manual uses the term UPS, the equipment may be marked "CVCF" according to customer specifications. If this is the case, remember that the term UPS in the manual is equivalent to CVCF.

2. Safety Precautions

Warranty

The warranty on this product may not cover all primary, secondary or tertiary damage resulting from error or failure of this unit, connected units or software.

Checking Warning Labels

Check to make sure that warning labels are displayed in the appropriate places (see page 6).

If labels are not present or are smudged and therefore illegible, contact the Toshiba Service Center .

- 3 -

2. Safety Precautions (continued)

If the unit begins to emit smoke or strange odors, immediately turn off circuit breakers 52R and 72B.

Continued use may result in fire. Contact the Toshiba Service Center.

WARNING

6 F 3 H 1 0 0 1

MANDATORY

Contact the Toshiba Service Center in the event of malfunction or failure.

This unit should be repaired only by authorized Toshiba service personnel. Servicing by untrained personnel may increase the scale of the failure or result in electric shock or injury.

MANDATORY

Do not attempt to modify or move the unit yourself or to have this done by a third party.

Electric shock, injury or failure may result if persons other than specially trained Toshiba technicians attempt to modify or move the unit.

Be sure to contact Toshiba if you wish modifications to be made or if you wish to move the unit.

PROHIBITED

Only open the front panel when performing necessary operations.*

Operating parts and high-voltage areas inside the UPS have been provided with covers as a safety precaution. Still, touching areas other than those that must be touched to perform necessary operations may result in electric shock, burns or other injuries.

* In this case, "necessary operations" means

operating circuit breakers/auxiliary switches and inserting/removing memory cards

MANDATORY

2. Safety Precautions (continued)

Do not open the rear door.

The parts inside carry high voltage. Touching them may result in electric shock, burns or failure.

WARNING

6 F 3 H 1 0 0 1

PROHIBITED

CAUTION

Operators should be qualified* personnel.

Operation of the UPS by unqualified or untrained personnel may result in electric shock, injury or failure.

* In accordance with customer stipulations

MANDATORY

Make sure the air vents on the front and top of the unit are not blocked.

Blocking the vents will cause the temperature inside the unit to rise and may result in fire or unit failure.

PROHIBITED

Make sure you understand the meaning of the warning labels on the equipment, and follow the precautions indicated.

Operating the equipment with an inadequate understanding of these matters may result in electric shock or burns.

• See Page 6 for the location of these warning labels.

MANDATORY

2. Safety Precautions (continued)

Checking warning labels

(1) The locations of the warning labels on the UPS are shown in Figure 2.1.

Check to make sure that these warning labels are in place.

Note that the placement and content of the warning labels may differ

depending on the capacity of the UPS. Verify the locations by referring to the warning label placement figure provided with the "Maintenance &

Inspection 6F3H1002" manual. (2) Read all warning labels and make sure you understand their meaning. (3) Make sure warning labels are alw ays legible. Do not allow them to become

smudged and do not remove or cover them up.

3. Handling Precautions

Perform daily and periodic inspections as noted in the maintenance and inspection plan.

In order to ensure a long service life and optimal performance, the equipment must be installed in a suitable environment, must be operated correctly, and must be given the proper daily and periodic inspections. Maintenance and inspections are particularly effective in preventing accidents caused by changes in components that will occur over time. Be sure to have periodic maintenance work and inspections done by Toshiba service and maintenance personnel. For more information on servicing programs and fee options, contact the Toshiba Service Center.

Operate the unit within the ambient conditions noted in the specifications.

Operating the unit outside these ranges may result in failure.

6 F 3 H 1 0 0 1

During operation, do not turn off the air conditioner for the UPS chamber and the battery chamber.

This will cause the temperature in these chambers to rise and may result in failure.

PROHIBITED

When starting or stopping the equipment, monitor the operation on the graphic display panel LCD and follow the procedures described in Chapter 8 "Operation".

Operating the unit in other than the prescribed manner may result in failure.

* The startup and stop procedures presented in this instruction

manual are the operating procedures for independent UPS nits. For system-wide operating procedures for when other distribution panels are present, refer to the corresponding operating procedures manual.

- 7 -

3. Handling Precautions (continued)

Do not turn the circuit breakers ON when control power source switch (8A) is OFF.

This may result in failure. Certain units also have a control power source switch (8D). This switch has the same functions as the switch 8A.

6 F 3 H 1 0 0 1

PROHIBITED

Do not turn the control power source switch (8A) to the OFF position when the circuit breakers are ON.

This may result in failure. Certain units also have a control power source switch (8D). This switch has the same functions as the switch 8A.

PROHIBITED

When operating the keys on the graphic display panel, hold down the key for at least 0.5 second.

The operation may not be performed if the key is held down for shorter periods of time.

When operating the reset key on the graphic display panel, hold down the key for at least 5 seconds.

The reset operation may not be performed if the key is held down for shorter periods of time.

- 8 -

3. Handling Precautions (continued)

When the unit has stopped due to failure, be sure to remove the memory card before resetting the LCD Failure Error screen on the panel.

Resetting (restarting) the UPS without removing the memory card will delete the data needed to determine the cause of the failure.

Do not leave the unit for long periods of time (1 week) with control power source switch (8A) in the OFF position.

This can cause the backup capacitor on the control board to become discharged and result in incorrect time display and other problems.
