4. External Wiring
WARNING
●Turn o󰀨 the power supply and use a tester or similar device to make sure that
the connecting cable is not live before connecting any wires in order to avoid
electric shock.
●Do not use CTs other than the supplied dedicated CT. Doing so may damage the
UPM101.
●If the UPM101 and its connected equipment are operated outside its specied
conditions, excessive heat and/or equipment damage may result. Check the
following before turning on the power:
a. Whether or not the power supply and the input signal values satisfy the
UPM101 specications.
b. Whether or not the external wiring is connected to the terminal locations as
per the specications.
●Do not operate the UPM101 in locations where ammable gas, explosive gas
or steam is present. It is extremely dangerous to operate the UPM101 in such
environments.
CAUTION
●Do not use an unused terminal as a relay terminal for another wiring.
●Do not cut the protective ground wire inside or outside the UPM101, or
disconnect the protective ground terminal connection. It is extremely dangerous
to use the UPM101 in such conditions.
●Do not operate the UPM101 if there is any possibility of problem with protective
functions such as the protective ground. In addition, make sure there is no fault
in the protective ground before operating the UPM101.

6.1 Integral Low-cut Power Setting
Integral low-cut power serves to prevent the instantaneous values for active power, apparent
power, and reactive power (optional) from being integrated if they are below the integral low-cut
power setting. Integral low-cut power is set as a percentage of the rated power value. In the
example presented here, integral low-cut power is set to “0.1%.” The procedure shown below
should be employed after turning the UPM100 power on, changing from the measured value
display to the parameter setting display, and displaying the “LOCUT” parameter (integral low-
cut power).

6.2 Settings Related to Integrated Pulse Output
If your UPM100 has integrated pulse output, the pulse unit and ON pulse width must be set.
Set the ON pulse width so that the maximum ON pulse width as calculated in the following
equation is not exceeded.
Pulse width (ms) = Pulse unit × 3600 × 1000² / Secondary-side rated power × VT ratio × CT
ratio × 1.2 × 2 (The pulse unit is kWh or kvarh.)
In the example presented here, the pulse unit-1 of electric energy is set to “500 Wh/pulse”, ON
pulse width-1 of electric energy is set to “100 ms”, electric energy pulse LAG/LEAD/REGENE*
is set to “LEAD”, pulse unit-2 of electric energy is set to “500 Wh/pulse”, and ON pulse width-2
of electric energy is set to “100 ms.”
*: If “reactive power option” is specied at ordering, either the reactive energy LAG side, LEAD side or regenerative energy is output as
the pulse output-2 of electric energy. Select “LAG,” “LEAD” or “REGENE” in the parameter “PLS.SEL”.
The procedure shown below should be employed after turning the UPM100 power on,
changing from the measured value display to the parameter setting display, and displaying the
“1.PLS” parameter (pulse unit-1 of electric energy).

2. Measured Value Display
This chapter describes display procedures, display ranges and other information for UPM100
with display function. For UPM100 without display function, see the communication function
User's Manual (IM 77C01H01-10E).
2.1 Active Energy, Apparent Energy and Regenerative Energy
The active energy and regenerative energy up to the present moment is indicated in “kWh” or
“MWh” unit (it is output in kWh unit during communication). The apparent energy is indicated
in “kVAh” or “MVAh” unit (it is output in “kVAh” unit during communication). However, if the
instantaneous active power or instantaneous apparent power is less than the previously
determined “integral low-cut power,” then it is not integrated. Active energy, apparent energy
and regenerative energy is recorded even during a power interruption.
Individual electric energy is displayed as shown in the table below, in accordance with the
measurement conditions.
For apparent energy, the unit is “VA” instead of “W.” For regenerative energy, a minus sign (-)
is always displayed. When “Integral resolution Wh” is specied at ordering, Type (3) in the table
is applied without the condition of “Secondary-side rated power x VT ratio x CT ratio” and the
display unit is “kWh” or “kVAh” only.
For Types (2) and (3), you can press the <Down> key to display as many as three digits
following the decimal point. (See the example display operations.)
Type Secondary-side Rated Power x VT ratio x CT ratio Integral Display Range Remarks

2.2 Reactive Energy (Optional Measuring Function)
The reactive energy up to the present moment is indicated in “kvarh” or “Mvarh” unit (it is output
in “kvarh” unit during communication). LAG (+) and LEAD (–) are separately integrated and
displayed. (A plus sign (+) is not displayed for LAG (+).) However, if the instantaneous reactive
power is less than the previously determined “integral low-cut power,” then it is not integrated.
Reactive energy is recorded even during a power interruption.
Reactive energy is displayed as shown in the table below, in accordance with the measurement conditions.
When “Integral resolution Wh” is specied at ordering, Type (3) in the table is applied without
the condition of “Secondary-side rated power x VT ratio x CT ratio.”
For Types (2) and (3), you can press the <Down> key to display as many as three digits
following the decimal point. (Display operations can be performed in the same manner as in the
example display operations in “2.1 Active Energy, Apparent Energy and Regenerative Energy.”
