Warning
●Prepare a safety circuit outside the UPM100 so that the entire system functions safely if the
UPM100 fails or malfunctions.
●Be sure to contact our sales representative before use if the UPM100 will be used in the
following situations:
- In an environment not described in the operation manual;
- In a way that causes substantial effects on medical devices, transportation equipment,
entertainment devices, safety devices, etc.
●Do not disassemble, repair or alter the UPM100. Fire or electric shock may occur.
●Do not install the product in the following environments:
- Locations with corrosive gases or combustible gases;
- Locations over which water, oil, or chemicals splash.
●Do not connect commercial power supply directly to the signal I/O terminal.
●Be sure to ground the protective grounding terminal.
●Do not connect AC adapters other than the dedicated adapter included for the UPM100 to
the power input connector.
●Be sure to check that the power is off before the following actions:
- Detachment of each connector;
- Wiring and connection of cables to the input terminal of electric power measurement;
- Connection to protective grounding terminals.
●Be sure to check signal names and pin assignment numbers and to wire cables properly
before connecting to a signal I/O terminal.
●Make sure to attach the terminal block cover included after wiring the electric wire.
Electric shock may occur.
●No connection is necessary for unused terminals.
●Be sure to check wiring and so on carefully before turning the power on.
●Use power supply voltage and load within the specified range and rating.
●Do not damage the power cords. Fire or electric shock may occur.
●Do not touch the power input connector and signal I/O terminal while power is on.
This may cause electric shock and malfunction.
●Electric shock may occur inside the main unit when the cover is opened. Internal capacitors
are charged even when power supply is cut off. Contact us for inspection and repair of
internal parts.
●Turn power off and unplug power cable immediately if smoke, abnormal smell, or abnormal
noise is detected.
Events that may cause death or severe injury to personnel
in case of misuse.

Precautions
●Do not install the product in the following environments:
- Locations where temperature or humidity exceeds specifications;
- Locations subject to drastic temperature fluctuations or icing and condensing;
- Outdoors
- Locations exposed to direct sunlight;
- Locations subject to dust accumulation;
- Locations with poor ventilation;
- Locations with excessive salt and metal powder;
- Locations where the main unit is subject to direct vibration and shock.
●Perform adequate shielding if the product is used in the following locations:
- Near power lines;
- Locations subject to strong electric field and magnetic field;
- Locations subject to noise such as static electricity and relays.
●Install the product as far away as possible from equipment generating high frequency, high
voltage, large current, surge, etc. Perform wiring of cables separately from these driving
force lines. Do not perform parallel wiring and identical wiring.
●Do not use the product if it is damaged.
●Tighten the input terminal screws of electric power measurement to the specified torque.
Loose tightening may cause short-circuiting, fire, or malfunction.
Tightening torque: 0.5N・m
●Use shielded cables for cables (external I/O).
●Be sure to have a time interval of five seconds or longer between turning power ON and
OFF.
●Use only after warming up for 30 minutes or longer following the start of power supply.
●Protective performance of the UPM100 may be lost if it is not used as specified.
●Cleaning
- Unplug the power supply when cleaning.
- Do not wipe with wet cloth, benzine, thinner, alcohol, etc. Doing so may lead to
discoloration and/or warping of the UPM100. When the product is dirty, clean it with a cloth
that is soaked with a diluted neutral detergent and tightly wrung. Afterwards finish with a
soft and dry cloth.
●Although the UPM100 is considered to be sufficiently shock absorbing during delivery, reusing
the same packaging materials may damage the product when a shock is encountered. When
sending this product to us for repair and so on, pack it with sufficiently shock-absorbing
materials.
●Handle this product as industrial waste when disposing. Be sure to remove the built-in
lithium batteries and dispose them according to classification of waste collection.

1-1. Main features of the UPM100
●This product can monitor single phase and three-phase voltage, current and electric
power.
●Insert the product into the electric wire of a motor to measure electric power. By measuring
the driving force using UTMⅡ, the conversion efficiency of the motor can be measured.
●The transmission efficiency of driving force transmission devices such as gears can be
measured by connecting two units of UTMⅡ.
●Measurement values related to electric power and driving force can be recorded, with
measurement time, simultaneously at an update frequency of 10 times per second.
●1000 points of the data described above can be saved in the UPM100.
●Data may be saved at any timing by key operation and input from external contacts.
●Temperature measurement at two points and two voltage inputs may be simultaneously
recorded.
●Alarm is output as a contact signal when voltage, current or electric power exceeds the
setting value.
●Measurements in between seven seconds before and three seconds after the alarm is
detected are recorded in the UPM100.
●Data recorded in the UPM100 can be exported to a USB memory in form of text data.

The following precautions are related to connection.
The precautions described in this text are important contents regarding safety.
Connect this product with accurate understanding of the contents.
Warning
●Do not connect commercial power supply directly to the signal I/O terminal.
●To avoid electric shock when connecting to the signal I/O terminal, connect the
indicator when power is off.
●Be sure to check signal names and pin assignment numbers properly before
connecting to the signal I/O terminal and apply proper wiring.
●Do not connect AC adapters other than the dedicated adapter included for the
UPM100 to the power input connector.
●Make sure to attach the terminal block cover included after wiring power supply.
Electric shock may occur.
●Be sure to check the wiring and so on carefully before turning the power on.
●Do not touch the I/O terminal while power is on. This may cause electric shock and
malfunction.
●To prevent danger, perform protective grounding of the UPM100 before connecting
measurement wires.
●When connecting the measurement target, turn its power off. Connecting and
disconnecting measurement wires without turning the measurement targets power
off is extremely dangerous.
●Refer to P.10 "2-3.Connecting the measurement circuit of electric power". Improper
connection may lead to, not only damage to the circuit and equipment to be
measured and the UPM100, but also human injuries.
●Do not input a value that exceeds the following value to the input terminal of electric
power measurement.
●Turn off the power of the measurement target when the power switch is OFF.
●When stripping a wire connected to the input terminal, make sure the bare section
of the wire does not protrude from the terminal. Tighten it so that the wire does not
come off from the terminal.
Precautions
●Tighten terminal screws to the specified torque. Loose terminal screws may cause
short-circuiting, fire, or malfunction.
●Use shielded cables for cables.

2-1. Connecting the power input connector
Connect the dedicated AC adapter of the UPM100 to
the power input connector of the main unit.
2-2. Connecting protective grounding terminals
This grounding terminal is for preventing electric shock accidents.
Use thick electric wire (approx. 0.75 mm2) for ground wires and be sure to ground.
1. Ensure that the power is OFF.
2. Connect the ground wire to the grounding terminal.
Warning
●To avoid electric shock, connect the product when the power is off.
●Be sure to apply grounding to protective grounding terminals in order to prevent
electric shock accidents.
Do not use screws other than those used for attaching the main body.

2-3. Connecting the measurement circuit of
electric power
Connect the main unit and electric wire to the electric power measurement terminal.
Before connecting to the terminal, attach a crimping terminal with a diameter of 8mm or shorter in
order to prevent the tip of the cable from scattering.
1. Ensure that the power is OFF.
2. Remove the terminal block cover.
(Single phase: three locations Three-phase: six locations)
3. Loosen the terminal screw until the terminal can pass through.
4. Slide the crimping terminal through the screw and tighten the screw.
5. Attach the terminal block cover.
6. Combine the ground wire of the electric power measurement circuit and the
protective grounding terminal.
