Caution about Safety
List of important warnings: Risks when UPS is not used correctly
Electric shock Do not remove the cover of the UPS.
High voltage parts inside UPS may cause electrical shock.
Electric
shock injury
Do not insert fingers or sticks into the cooling fan or the
ventilation.
Doing so may cause electric shock or injury.
Electric shock Maintenance including the daily inspections (battery
replacement, cooling fan replacement, etc.) should be
performed by a professional technician.
Failure to do so may cause electric shock.
This UPS requires grounding (Class D grounding or
higher). When connecting to the input power supply,
connect a ground wire to the AC input protective grounding
terminal. Failure to do so may cause electric shock.
Warning
Caution Caution indicates that slight or moderate injury may occur,
the UPS or user's property may be damaged.
"Warning" indicates that death or serious injury may occur.
When connecting the UPS to the input power supply,
connect the active wire to the AC input L/R terminal and
the inactive wire to the N/S terminal. Also, connect the
ground wire to the AC input protective ground terminal.
Similarly, when connecting the output of the device,
connect the active wire to the l1/U1 terminal and l3/V1
terminal for AC output (at 100 V). For AC output (at
200V), connect to l1/U2 and l2/V2, and connect the
ground wire to the ground terminal.
Incorrect connection may cause noise, malfunction,
failure, or electric shock.
When maintaining the connected device, be sure to turn
off the power supply to the connected device. Turn off the
breaker on the distribution board and disconnect the AC
input terminals. Failure to do so may cause electric shock.

iv
Injury Do not step on or put an object on the UPS.
Injury Damage The UPS is heavy. Caution in handling the UPS.
Take out the UPS in a level and flat place. The weight of
the UPS is as follows:
•M-UPS050AD1S/2S: 180 kg (without battery: 125 kg)
•M-UPS075AD1S/2S: 235 kg (without battery: 160 kg)
 M-UPS100AD1S/2S: 300 kg (without battery: 190 kg)
This UPS is not designed for medical equipment that
comes in contact with the human body.
Do not place objects affected by magnetism near the
UPS. Replace the battery periodically. Continued use
of a UPS at the end of its battery life may result in battery
leakage or smoking.
Replace the battery with a new one specified by Fuji
Electric. Using unspecified batteries or mixing old and
new batteries may cause UPS failure or trouble.
When performing a rolling blackout, or when
unplugging the AC input plug from the input power
outlet, or when turning off the input breaker on the
rear of the UPS, make sure that the RUN LED (green)
is blinking slowly (1.6 second cycle). When the
distribution board breaker is turned off, the AC input plug
is unplugged from the input power outlet, or the input
breaker on the back of the UPS is turned off, the built-in
battery is discharged because the condition is the same
as a power failure when the RUN LED is lit. This may
cause battery deterioration and shorten the battery
replacement cycle.
Damage
Warning label
Never remove the labels.

v
Caution for use
IMPORTANT
Do not install and store the UPS in the following places:
 Outdoor location
 Exposed to the wind and rain
 Extremely humid and dusty
 With corrosive gas or salt
 Direct sunlight
 Near sparks or heating element
 Extremely hot or cold, where the temperature fluctuates greatly
 With vibration and shock
Do not perform the battery check in succession.
When the battery check is performed, the internal battery actually
discharges to check the voltage.
Consecutive battery checks may cause battery degradation and shorten
the battery replacement cycle.
If the UPS is not used for a long time, charge the battery every two
months. Charge the battery by operating the UPS for 12 hours or more
every two months. After charging the battery, perform the battery check.
If the UPS is not used for a long period of time, the battery may become
over-discharged due to self-discharge, rendering the UPS unusable.
Disposal of used battery has legal restrictions
Please follow any local, county, regional or state guidelines for the disposal
of batteries.
Do not block the vent hole and cooling fan, Do not use UPS where the
air is not well ventilated.
The UPS is equipped with vents and cooling fans to cool the inside of the
UPS; the internal and ambient temperatures of the UPS may deviate from
the rated specifications.
Replace the cooling fan periodically.
Continued use after the fan has reached the end of its service life may
cause the internal temperature of the UPS to exceed its rating.

Caution for use
vi
The allowable voltage between the UPS input electrical cable and ground is
250VAC.
Applying a voltage of 250 VAC or higher may damage the filter circuit in the input
section.
The allowable input surge voltage of this UPS is 5kV peak (1.2 x 50µs).
Applying a surge voltage exceeding 5kV peak may damage the filter circuit in the input
section.
The input voltage of the UPS is voltage 15%.
When input voltage is different from the rated voltage, install a transformer outside the
UPS to convert the voltage. Applying a voltage higher than the input voltage range
may damage UPS.
Connect the UPS to the input power supply within the rated input voltage range
of the connection device.
In bypass operation, the input voltage of the UPS is output directly to the
connection device. Applying the voltage that exceeds the rated input
voltage range of the connected device may damage the connected device.
When using a generator temporarily during a planned power outage, use a
generator that meets the following specifications.
Connecting a generator that does not meet the following specifications to the input
section of the UPS may cause the UPS to malfunction or be damaged.
 Voltage variation: within 15% of rated voltage
 Frequency variation: within 5% of rated frequency (1Hz per second)
 Voltage waveform distortion: within 5%
 Voltage zero-cross condition: No more than one zero-crossing during one cycle.

2.2 How the Product Works
During normal operation
This UPS operates with AC power as input and supplies constant voltage
output to connected devices. At the same time, it charges the product's
built-in battery to prepare for battery operation. The output frequency is
synchronized with the input frequency.
Electricity flow during normal operation
Battery power failure
If a power failure or input power voltage/frequency error occurs, the UPS
starts discharging from the battery and continues to supply stable power to
the connected device. The system switches to battery operation without
interruption. When the input power is restored (when the voltage of the
input power returns to within the rating), the UPS automatically returns to
the normal operation described above.

Automatic Bypass Operation
When the abnormalities occurred in the UPS during the normal operation,
the UPS switches to the bypass operation automatically. During the
bypass operation, the UPS sends the input voltage to the output directly
and supplies the electric power to the connected device. In this case, even
if the power failure occurs, the UPS becomes the power failure state
without switching to the battery operation.

Manual bypass operation
Manual bypass operation can be switched to bypass operation during
normal operation. Press the RESET and BYPASS switches
simultaneously for 3 seconds.
Press again for 3 seconds to return to normal operation. In this case, even
if the power failure occurs, the UPS becomes the power failure state
without switching to the battery operation.
