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
This manual and the labels on the UPS main unit contain important information designed to
ensure that the UPS unit is used correctly and safely and prevent property loss and injury to
operators and maintenance personnel. Operators and maintenance personnel should follow
all precautions noted in the manual and should have a thorough understanding of the
meaning of the safety signs and safety symbols shown below.

2. Safety Precautions (continued)
WARNING
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.
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.
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.
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

2. Safety Precautions (continued)
WARNING
Do not open the rear door.
The parts inside carry high voltage. Touching them may
result in electric shock, burns or failure.
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
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.
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.

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 always legible. Do not allow them to become
smudged and do not remove or cover them up.
* The nameplate B is attached at the ground wire connection points in each section.
** The nameplates E are mounted in the vicinity ofthe main circuit transformers and
reactors that can be seen from the back of the panel.

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.
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.
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.

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.
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.
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.

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.
