Install The Inverter - Hitachi P1-00080-L Basic Manual

Chapter 2
Installation environment
•
Avoid installing the inverter in a place where the
inverter is subject to dust, corrosive gases,
combustible gases, flammable gases, grinding fluid
mist, or salt water.
•
Foreign particles entering the inverter will cause it
to fail. If you use the inverter in a considerably
dusty environment, install the inverter inside a
totally enclosed panel.
Installation method and position
•
Install the inverter vertically and securely with
screws or bolts on a surface that is free from
vibrations and that can bear the inverter weight.
•
If the inverter is not installed properly, its cooling
performance may be degraded and tripping or
inverter damage may result.

Mounting in an enclosure
•
When mounting multiple inverters in an enclosure
with a ventilation fan, carefully design the layout
of the ventilation fan, air intake port, and inverters.

Position of ventilation fan
 When the inverter is installed below ventilation fan,
the incoming dust may hit the inverter. Place in a
position to avoid this falling dust.

Reduction of enclosure size
•
External heat sink installation may reduce internal
heat emission resulting, a reduction on enclosure
size.
•
External heat sink mounting for the inverter
P1-00044-L to P1-00228-L (P1-004L to P1-037L)
and
P1-00041-H to P1-00126-H (P1-007H to P1-037H)
requires an optional fitting metal.
•
Other models than above can be installed with the
originally attached fitting metal. To mount the
inverter in an enclosure for external heat sink, cut
out the enclosure panel according to the specified
cutting dimensions.
•
The cooling section (including the heat sink)
positioned outside the enclosure has a cooling fan.
Therefore, do not place the enclosure in any
environment where it is exposed to water drops,
oil mist, or dust.
•
The heat sink part reaches a high temperature.
Install a protection cover as needed.
