Inspection/Installation

Inspection of the New UPS Equipment

Upon receipt of the UPS, a careful inspection for shipping damage
should be made.

After Unpacking:

1) Check the unit for loose, broken, bent or otherwise damaged
parts. If damage has occurred during shipment, keep all original
packing materials for return to shipping agent. Warranty will not
apply to units damaged during shipment.

2) Check to see that the rated capacity and the model number
specified on the nameplate conform to the order specifications.

Installation Precautions

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 vibration.

3) Install the unit where the ambient temperature is between 32°
and 104°F (0° and 40°C).

4) Do not install the UPS in areas that are subject to high humidity.

5) Do not install the UPS in a location that will cause direct sunlight
to shine on the unit.

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

7) Avoid installation near sources of electrical noise. Always make
sure that the unit earth ground is intact to prevent electrical
shock and to help reduce electrical noise.

8) Do not install where water or any foreign object may get inside
the UPS.

9) This UPS generates and can radiate radio-frequency 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 close 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.

Starting the UPS System

Once the modules have been connected as shown in the preceding
section (UPS Connections, page 10) the UPS system is ready to be
started. There are two ways to start the system: from AC input
power (if present) or from batteries. If not already done, switch the
input breaker on (figure 1, page 9). If the “AC Input” LED is lit,
proceed on to “Starting when AC power is available”. If the LED is
not lit, there is no AC power available. If the unit is to be started
when AC power is not available proceed to “Starting on DC power.”

Starting When AC Power is Available

If the system is being started with AC input power the system is
started by switching the RUN/STOP switch to the RUN position
(RUN = I, STOP = 0). When the RUN/STOP switch is in the RUN
position both the “AC Input” and the “On Line” LEDs should be lit.
When the unit is started with AC input power it is advisable to allow
time for the batteries to fully charge before any load is connected
(see “Battery Recharge Time”, page 15).

11

TOSHIBA

Starting on DC Power

If no AC power source is available, or if the AC input power is
outside of the allowable range for voltage or frequency, the UPS can
be started from battery power. The length of UPS operation time on
battery power depends on the number of attached battery modules
and the amount of load the UPS is supporting. To start the UPS
from battery power follow these steps:

Step 1: Make sure the RUN/STOP switch is in the STOP position. If
the UPS is being started on DC power because the AC power is out
of range, the input breaker must be in the OFF position (figure 1,
page 9).

Step 2: Press the “Startup on Battery” button. The UPS will beep
indicating that AC power is not available and the Startup on Battery
mode has been activated.

Step 3: Switch the RUN/STOP switch to the RUN position. This
must be done within 5 seconds of the Startup on Battery mode
activation for the unit to startup using batteries.

Once the unit has started, the “On Line” LED will light, indicating that
the inverter is running and power is available at the output
receptacles. If the RUN/STOP switch is not switched to the RUN
position within those 5 seconds, the unit will return to shutdown
mode.

Stopping the UPS

There are two ways of turning the UPS off: switching from on line to
bypass mode, or completely shutting down.
Option 1: The first option is to place the UPS into bypass mode.
Bypass mode means that if there is AC power available, the UPS will
route power directly from the input source to the connected loads
without any conditioning. The UPS inverter is off during this state,
but the attached loads do not lose power during the transition. To
place the UPS into bypass mode, switch the RUN/STOP switch to
the STOP position. This mode is most often used manually during
maintenance and programming operations or automatically upon the
occurrence of an internal UPS fault. (For more information
concerning bypass mode see appendix E.)
Option 2: The other option is to turn the UPS off completely. This
means that in addition to the UPS’s inverter shutting down, all power
will be stopped to any equipment attached to the UPS. To shut
the UPS down completely switch the RUN/STOP switch to the STOP
position. Then switch the input breaker off (figure 1, page 9). Once
the input breaker has been switched off, all the LEDs should turn off.
(If the RUN/STOP switch is in the RUN position when the input
breaker is switched off, the unit will switch to battery backup mode.
The unit will continue to run for as long as the available battery
reserves can support the connected loads.)

Notes

Parallel operation occurs when
input power is present, but
inadequate to fully power the
connected load. The batteries
are used to supplement the
AC input power. The UPS will
return to normal operation
when full input power returns.

All other display conditions constitute either a warning or a fault condition. These conditions are explained in the section titled “Troubleshooting”

14

(page 22) in the charts on Warnings and Faults.

Note 1: The level meter, which consists of the LEDs labeled 20% through 150%, will light according to the current amount of load connected.
As the load exceeds one level, the next level will begin to blink, increasing the blink rate as the load increases until that full percentage is
reached. For example, if the unit is loaded to 40% of maximum output power the 20% and 40% LEDs will be lit. If another small load is added
increasing the load to 45% the 60% LED will begin to blink. If a little bit more load is added so that the total load becomes 50% the 60% LED will
blink faster. This will continue until enough load is added to equal 60% of the maximum output power at which time the 60% LED will stop
blinking and light continuously.

Note 2: The level meter described in note 1 above also displays the remaining battery time when the unit is in backup mode. If the batteries are
fully charged when the unit switches to backup mode the 20% through 100% LEDs will light. As the batteries begin to discharge, the LEDs
starting from the top will blink rapidly then slowly and will then turn off as the battery time runs down. For example if the unit has been running on
battery power and there is 90% battery capacity remaining the 20% through 80% LEDs will be lit and the 100% LED will be blinking.

Battery Backup Time

The exact amount of backup time provided will vary depending on
the UPS model being used, number of batteries, condition of the
batteries and other factors. However, the chart below gives the
times that can be expected from the standard units with batteries in
good condition. For greater backup time, an additional battery
module may be added to the standard unit. Only one additional
battery module may be added to the standard unit. For longer
runtime options contact your Toshiba sales representative or the
Toshiba marketing department at [phone] or by e-mail at
[e-mail].

2400 VA 9 min / 26 min 30 min / 64min

* Times given are approximate and will vary depending on the age of the batteries, the
battery temperature, the number of previous discharges and the type of load.

Load Shed Function

The 1700 Series includes a load shed function. During battery
backup operation, this function allows the load connected to two of
the receptacles (figure 1, page 9) to be turned off in an effort to
conserve power for more critical loads. The battery level at which
these two receptacles will be turned off, or “shed”, can be set by the
user (see “The Function Control Button”, page 16). By default, this
feature is configured so that these two receptacles will remain on for
the full battery backup time available (no “shedding”)

Battery Recharge Time

The following table gives estimates on time required to recharge the
UPS’s batteries. The recharge time may vary depending on the
battery temperature, the age of the batteries, and other factors.

Table 2

Battery Recharge Time*

Unit With 1 Battery Module With 2 Battery Modules

2000 VA 4 ½ hours 9 hours

2400 VA 4 ½ hours 9 hours

* Recharge times are to 90% full capacity.

Fan Speed

The 1700 Series Rackmount UPS has variable speed fans. The fan
speed will vary depending on a number of factors. As the load

15

TOSHIBA

placed on the UPS increases the fan speed will increase. The
temperature of the environment the UPS is operating in can also
cause the fan speed to increase. (For a more detailed explanation of
the variable speed fan function refer to appendix B)

Battery Check Function

During startup the UPS will perform an automatic 'Battery Check' to
detect whether a problem exists in the battery circuit. If the batteries
pass the test, the unit will start normal operation. If a problem is
detected during the test the “Warning/Fault” LED will activate. Other
LED’s may also activate. If this occurs please refer to the
“Troubleshooting” section on page 20 for a description of the
problem and possible solutions. It is important to note that when

the UPS has detected bad batteries, the battery backup mode is
disabled. The unit will continue to operate and provide clean power;

however, since there is no battery power available, the unit cannot
provide backup power if input power is lost.

The Function Control Button

The function control button is located on the display panel (see
“Display Panel Layout”, page 11). This button is used to perform
several different UPS operations, including initiating self test,
providing programming options, and silencing the alarm. A brief
description of each function follows along with a step by step guide
to accessing each function.

1) Self-Test. In order to perform a self-test the UPS must be
operating in the normal mode (see “UPS Display Status and
Operating Condition”, page 13). To initiate the self-test simply
press and hold the Function Control button until the audible
alarm sounds. The self-test performs the same battery check
described above.

2) Alarm Silence. The alarm silence feature is used to stop the
audible alarm from sounding. Any time the audible alarm is
sounding pressing the Function Control button will silence the
alarm.

3) Programming Mode. There are three programming options:
load shed, output enable/disable after input overvoltage backup,
and reset battery installed date. In order to enter the
programming mode the UPS must first be operating in Bypass
mode without faults (see “Stopping the UPS: Option 1”, page

12). Then press and hold the Function Control button. (“Press
and hold” always means to hold until the unit gives audible
feedback). The unit will give an audible feedback indicating the
unit is in programming mode. (If at anytime while the UPS is in
the programming mode there is one minute of inactivity the UPS

16

TOSHIBA

will automatically exit the programming mode and return to
bypass operation.) What follows is a step by step guide to
navigating in the programming mode, followed by a detailed
description of each option.

A. Load Shed. The backup LED will light indicating the UPS is now

ready to make changes to the load-shed settings (see “The Load
Shed Function”, page 15 for an explanation of load shedding).
To accept this option press and hold the Function control button.
A.1 The UPS comes from the factory set so the load shed

receptacles function for the full battery backup time. The
LEDs on the right side of the display will light to indicate the
current setting for the load-shed level. For example, since
the default factory setting is for no load shed, the first time
the option is accessed no LEDs will be lit. Pressing the
button once will cause the 20% LED to light. This would
indicate that the load shed receptacles should be turned off
when there is 20% battery power remaining. Pressing the
Function Control button successive times will increase the
load shed level in 20% increments.

17

TOSHIBA

A.2 Once the option is set to the desired level, press and hold

the Function Control button. This will save the new load
shed level setting. The UPS will indicate that the value has
been stored by blinking the LEDs. After blinking the LED for
a short time the UPS will exit the programming mode and
return to bypass operation. To return the system to normal
operation switch the RUN/STOP switch back to the RUN
position.

B. Output Enable/Disable After Input Overvoltage Backup. Press

the function control button. The unit is now ready to change the
output enable/disable after input overvoltage backup option.
This is indicated by the 150% LED turning on. This setting
determines whether the UPS will go to bypass in the case of an
input overvoltage fault. To change this setting press and hold the
function control button.
B.1 This setting is set to disable output at the factory. Pressing

the function control button causes the 100% LED to light,
indicating output has been enabled. Pressing it again will
change it back to disabled and the 100% LED will go off.

B.2 Once the option is set as desired, press and hold the

function control button to save the setting. The UPS will
indicate the setting has been saved by blinking the LED(s).
The LED(s) will continue to blink for a short time after which
the UPS will exit programming mode and return to bypass
operation. To return the system to normal operation switch
the RUN/STOP switch back to the RUN position.

C. Reset Battery Installed Date. This should be done whenever a

new battery pack is installed. Press the function control button.
The unit is now ready to reset the battery installed date. This is
indicated by the Battery LED turning on. Once this mode has
been entered press and hold the function control button to reset
the battery install date to the current date. The UPS will indicate
that the date has been reset by blinking the Battery LED for a
short time after which the UPS will return to bypass operation.
To return the system to normal operation switch the RUN/STOP
switch back to the RUN position.

18

TOSHIBA

Fixed Frequency Mode

The 1700 Series Rackmount UPS has the option of operating in a
fixed frequency mode. Normally the UPS operates in the frequency
auto-detect mode. If a specific output frequency is required (i.e.
50Hz or 60Hz) the UPS can be set at the factory to supply the
desired frequency regardless of the input frequency (input frequency
must be within allowable limits, see Specifications on page 29). For
a unit already in use the output frequency can be set through
software. For instructions on setting the output frequency through
software please contact Toshiba at [phone] or by e-mail at
[e-mail]. It is important to note that when the

UPS is operating with a fixed output frequency, output is
disabled in bypass.

Adding an Additional Battery Module

Note: Only one additional battery module may be added to the
standard unit. Figure 4 shows the standard unit with one additional
battery module added. To install an additional battery module follow
these steps:

1) Make room in the rack for the additional battery module to be
placed below the other modules. Secure the new battery module
in the rack.

2) Plug the new battery module output power cord into the battery
input plug on the battery module.

Option Card Slot

The option card slot is a standard feature. An optional network
adapter card slides into the slot which is located on the back of the
electronics module (figure 1, page 9). This optional interface allows
the UPS to be monitored across the network or from any point on the
Internet (refer to the Communication Option User Manual for a more
detailed explanation of this option).

Troubleshooting

Warnings and Faults are those abnormal conditions that can occur
and could cause the unit to stop normal operation. These conditions
are detected by the protective circuitry in the unit. The UPS
“Warning/Fault” lamp will light red when a warning or fault occurs.
"Troubleshooting" involves monitoring the LED’s on the front panel
and then interpreting the readout by using the warning and fault
mode display charts that follow. Only the state of the LED’s listed in
the chart should be considered. Other LED’s might be active;
nevertheless, only those listed under the column “LED state” should
be considered when diagnosing a warning, or fault.

Warning/Fault Modes
All warnings will cause the red “Warning/Fault” LED to flash. All
faults will cause the red “Warning/Fault” LED to light continuously.
Some warnings and most faults will cause the UPS to transfer to
bypass mode. In many cases, after the condition that caused the
fault is corrected the unit will automatically transfer back to normal
mode. For those cases where the unit does not transfer back
automatically contact your Toshiba UPS service representative at 1­877-867-8773 (outside the U.S. call 713-466-0277).

The batteries have less than
30% power remaining. The
warning will continue until either
the batteries become completely
exhausted or AC input power is
restored.

An output current limit warning
is typically a sign of
misapplication. The load may
not be appropriate for UPS
support. For further explanation
contact your Toshiba UPS
service representative at 1-877­867-8773 (outside the U.S.

call 713-466-0277).

The temperature of the UPS
operating environment is too
high. Causes of this condition
include allowing the room
temperature to exceed 104°F
(40°C), a blocked vent or direct
sunlight on the unit. The unit will

possible cause would be a
problem with the battery module,
which could prevent the unit
from providing backup power.

This warning will occur if the input
voltage drops below the minimum
allowable voltage. If the unit was
online when the warning occurred it will
transfer to battery backup. After the
backup the output will shutdown. If the
unit was in bypass the output will be
turned off. The unit will reinitialize the
startup sequence if input power returns
to within specified limits.

This warning will occur if the input
voltage exceeds the maximum
allowable voltage. If the unit was
online when the warning occurred it will
transfer to battery backup (see note 2).
If the unit was in bypass the output will
be turned off. The unit will return to
normal operation if input power returns
to within specified limits.

Storage of UPS Equipment.

General Guidelines

If the UPS equipment is to be stored; 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) Allow UPS to be operated for 4 hrs to ensure that the batteries are fully

charged.

2) Stop the unit (see "Stopping the UPS" on page 12).

3) Place the unit's Input Breaker switch in the "off" position (see “Electronics

Module Layout”, page 9).

Storing:

1) Store within a temperature range of -20° to 40° C (-4° to 104° F). If the

UPS is stored at a temperature outside of the allowable operating range,
allow time for the unit to reach equilibrium with the ambient temperature
before starting the UPS.

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 21° C (70° F). Higher ambient

temperatures cause UPS batteries to need recharging more frequently.

Recharging requirements during storage:

Recharging the batteries requires that the battery module be connected to
the UPS and the UPS must have AC input power available. The UPS can
be in either the on line or bypass mode. (See “Starting the UPS”, page 11,
and “Battery Recharge Time”, page 15).

1) If stored in an ambient temperature less than 20°C (68°F), recharge the

batteries every 9 months.

2) If stored in an ambient temperature of 20° to 30°C (68° to 86°F),

recharge the batteries every 6 months.

3) If stored in an ambient temperature of 30° to 40° C (86° to 104°F),

recharge the batteries every 3 months.

Disposal

Please contact your local environmental agency for details on disposal of
electrical components and packaging in your particular area. 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 [phone] for
more information about recycling.

Preventive and Scheduled Maintenance/Parts
Replacement

Preventive Maintenance

Toshiba's 1700 Series of rackmount UPS systems have been
designed to provide years of trouble-free operation requiring a
minimum of preventive maintenance.

The best preventive measure 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 exterior of the unit, especially around
ventilation openings. Schedule authorized Toshiba service centers
to perform internal parts inspections annually, or call a Toshiba UPS
service representative at 1-877-867-8773 (outside the U.S. call 713­466-0277).

CAUTION

Parts Replacement

The following list shows intervals for periodic maintenance and
replacement of certain UPS parts.

1) Battery Module: Replacement should be done once every 3 to 5
years at a minimum.

2) Output Fuses: Replace once every 7 years (always replace
fuses with same fuse type and rating).

3) Cooling fan: Replace once every 3 years. (Fan replacement
must be done by Toshiba authorized service personnel.)

Proper maintenance of the battery system
of this unit is essential to the safety and
reliability of the UPS system.

TOSHIBA

Appendix B: Fan Speed Control

The fans in the 1700 Series will operate at any of four different speeds
depending on the environment and system conditions. In the first stage
the fans are off. As the load and or the temperature increase the fans
will subsequently go to low, medium or high speed as required.

The temperature reference given on the graph above refers to the
temperature inside the UPS. There will typically be a 5°C difference
between the internal and external temperature. The 10% hysteresis
shown is to ensure that the unit will not oscillate between fan speeds.
When the output power reaches a level that requires the fan speed to
increase the load will have to be reduced 10% below that level before the
fan speed will return to the lower speed.

32

TOSHIBA

Appendix C: System Overload Rating

The 1700 Series Rackmount UPS is capable of supporting short duration
overloads. When operating in the On Line mode output overloading of
125% of the rated output current can be supported for 1 minute, and
150% for 30 seconds. If the overload continues the unit will switch to
bypass mode. When in bypass mode the 1700 Series overload capacity
is limited by the input breaker. The following graph shows the response
of the breaker depending on the applied load. The two lines shown on
the graph represent the upper and lower limits of the breaker response.
The response of a particular breaker could fall anywhere between these
two lines.

If the load capacity of the breaker is exceeded the breaker will trip,
shutting down both the UPS and the attached loads. If the breaker’s
capacity is not exceeded the unit will continue to operate in the bypass
mode until the applied load is reduced. When the load on the UPS is
reduced to within the specified limits the UPS will automatically return to
On Line mode.

33

TOSHIBA

Appendix D: Parallel Operation

The 1700 Series Rackmount UPS offers a standard feature that allows
the unit to operate with very low input voltage without de-rating the
output power. If the input voltage drops below a certain point the unit will
switch to parallel mode. Parallel mode means that the unit is using the
available input voltage and supplementing with battery power. Because
battery power is being used, the time the unit can operate in parallel
mode is limited. However, the time will be longer than that available
when the unit is operating on battery power alone. The point when the
UPS will enter parallel mode will vary depending on the output load. The
following graph shows the various stages based on full output load and
75% output load.

As shown by the graph the lower the output load the lower the input
voltage can go before parallel mode is activated. However, the minimum
input voltage will always remain at 50% (60VAC for a 120VAC system).

34

TOSHIBA

Appendix E: Bypass Undervoltage / Overvoltage

When the 1700 Series Rackmount UPS is in bypass mode the
undervoltage and overvoltage limits are restricted to +/-10% of the rated
input voltage. If the input voltage is outside of this voltage window the
UPS output will be turned off. There is a 5% hysteresis associated with
both the upper and lower limits. This means that once output has been
turned off the input voltage will have to be within ±5% of the rated input
voltage before the startup sequence will reinitialize. (To start the UPS
when the input power is outside of the allowable range see the section
entitled “Starting on DC Power”, page 12.)

When the UPS is started, if the RUN/STOP switch is in the STOP
(bypass) position the unit will start in the on-line mode for 1 second
before switching to bypass mode. If the input voltage is out of range the
UPS will turn off the output after 1 second rather than switching to
bypass.
