Installation
Precautions
This inverter is an electronic control unit. Take special care concerning the installation environment.
• Confirm that the input power is within + 1 0% of the rated value.If the input power voltage range
tolerances are exceeded during use, the protective circuits may function or the inverter may
be
damaged.
·Avoid
installation in hot and humid locations,
where condensation or freezing may occur.or
where water,dust,or metal chips may come into
contact with the inverter.
• Do not install the unit
in locations that
experience large
vibrations.
• Install
in
a location
free of corrosive gases
or cutting fluids, etc.
• Use the unit within an ambient temperature of
-10 to 40
·c
.

Because the inverter radiates
heat, when installing
in
a
panel take special care
concerning ventilation and
panel space. Removal of
the cover is recommended
when using
in
a panel to
ensure maximum longevity
and reliability.
• The inverter may malfunction if the
following types of devices are
installed nearby, so use proper
precautions.
·Solenoids
• Brakes
-----1
• Electromagnetic
contactors
• Fluorescent lights
Install
a surge killer
on the exciting coil.
•
Resistors

Keep away from the inverter
• Ground the G/E
terminal to prevent
electrical shock and
malfunction due to
noise.
Attach the unit to a non-combustible material such as a metal panel. To
ensure adequate ventilation, maintain the following installation spaces, and
always
install the unit vertically
in
the longitudinal direction. When installing
multiple inverters
in
a row, leave a clearance of
at least 1
Ocm
between each unit. This clearance
can be reduced depending on the environment
or by adding fans.
~
l:;p
(For 37kW and larger units, leave a clearance of
at
least 20cm above and below the inverter to
allow for fan replacement and wire bending
space.)
Contact the Engineering Department for further
details.
Inverter life depends greatly on the ambient temperature. Make sure
that the ambient temperature of the installation location dose not exceed the
maximum ambient temperature
rating(40°C).
5cm
Measure the temperature at the positions shown
in
the diagram on the right,
and confirm that it is less than the maximum ambient temperature rating
(40 °C).
(S0
°C or less when the cover is removed.)
22kW and larger units can be used up to an ambient temperature
of
so
·c.
(Do not remove the cover from 22kW and larger units.)
* Always install the inverter
in
the longitudinal direction
on
a vertical surface.
