Precautions concerning preparation before use
Please read the following items before use.
(1) Transport
Avoid application of vibration and impact as much as
possible during transport.
In situations where it is possible that transducers will be
subject to excessive vibration or shock, remove the
transducer from the panel before transportation.
(2) Check the model name and rating
As a precautionary measure, check the model name and
specifications such as input, output and auxiliary power
supply before use.
(3) Adjustment
Generally, transducers are adjusted before shipment from
the factory and do not require adjustment. To perform
adjustment for matching with receiving-side equipment,
perform adjustment while avoiding the application of
excessive force to the adjusters. Not doing so may cause
failure of the adjusters.
Avoid touching the adjusters in ordinary circumstances.
(4) Insulation resistance test and withstand voltage test
Please read the following carefully before performing an
insulation resistance test or voltage test. Not doing so may
cause failure.

Usage precautions
Please pay attention to the following items during use.
5
For instrumentation transducers where the input and
output circuits are not insulated, do not perform
withstand voltage testing between the input and output.
Breakage will occur.
The withstand voltage test will cause the dielectric
breakdown of internal elements, and may cause
equipment failure or fire.
Do not perform a withstand voltage test between
input and output for non-isolated models
Precautions concerning repair upon failure and
treatment of abnormality
If an instrument malfunctions contact the nearest branch of
Mitsubishi Electric System Service Co., Ltd. or Mitsubishi
Electric.
6
Use transducers according to their ratings. Not doing
so may cause significant error, failure or fire due to
overheating.
For input values outside the rating range, the output
value will be outside the rating range.
Use transducers according to their ratings
For models requiring settings, read the relevant
instruction manual carefully before performing settings.
Setting errors or unset items may cause abnormal
operation and alarms may not function properly for
receiving-side equipment; for example, if no value is
set, no alarm will be activated for the output signal.
Ensure the settings are correct
With the active power, reactive power, power factor,
phase angle and frequency transducers, an error may
occur if the input voltage is outside the specified
operating range (guaranteed value: 90~110% of the
rated voltage).
Additionally, malfunction may occur if the input voltage
drop is significant (less than 60% of the rated voltage).
Do not lower the input voltage
