Since the PCU primarily consists of semiconductors, there are few components which have
the limited service life. However, their elements may deteriorate depending on the environment
and condition in which they are used. You need to inspect the PCU regularly in order to use its
functions in its best condition.
The standard inspection period is once every 6 months to a year. However, it's advisable to
shorten the inspection interval depending on the operating environment.
If the inspected items are not within the criteria, make necessary corrections to meet the criteria.

Are the voltage
fluctuations within the
standards when you
measure it with I/O
terminals?
Is the ambient
temperature
appropriate?
(If you use the PCU in
a panel, the ambient
temperature in a panel
is the ambient
temperature to be
inspected.)
Is the ambient humidity
level (humidity in a
panel) appropriate?
(If you use the PCU in
a panel, the ambient
humidity level in a
panel is the ambient
humidity level to be
inspected.)
Is the PCU subject to
direct sunlight?
Is there any
accumulation of dirt,
dust, saline materials
or iron powder on the
PCU?
Are there any droplets
of water, oil, or
chemicals on the
PCU?
Does the environment
contain corrosive gas
or flammable gas?
Is there any direct
vibration or impact on
the PCU?

It must be between
10% and 90% with no
dew condensation.
There must be no
direct sunlight.

None
It must be within the
specification range of
vibrations and impacts.
Criterion
Check the power supply
between terminals with a tester
and change the supplied power
amount to meet the criteria.
Use a thermometer to measure
the PCU ambient temperature,
and adjust the ambient
environment so that the
temperature is within the
operating ambient temperature
range.
Use a hygrometer to measure
the PCU ambient humidity
level, and adjust the
environment so that the
humidity is within the operating
ambient humidity range of 10%
to 90%.
In particular, make sure there is
no dew condensation because
the temperature can change
suddenly.
Shield the PCU from sunlight.
Remove any accumulation and
shield the PCU.
Remove any accumulation and
shield the PCU.
Check the environment based
on the smell or with a gas
sensor.
Place cushions, etc. to offset
vibrations and impacts.
