Chapter 2
Installation environment
•
Avoid installing the inverter in a place where the
inverter is subject to dust, corrosive gases,
explosive gases, flammable gases, grinding fluid
mist, or salt water.
•
Foreign particles entering the inverter will cause of
failure. If you use the inverter in a considerably
dusty environment, install the inverter inside a
totally enclosure.
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.

temperature. Plan the layout properly so that the
inverter ambient temperature will remain within
the range specified in the specification table.

Reduction of enclosure size
•
External heat sink installation may reduce internal
heat emission and reduce the enclosure size.
External heat sink mounting for the inverter
SH1-00041-H～SH1-00126-H(SH1-007H～SH1-037H)
requires an optional metal fitting.
•
Models other than the above can be mounted
using the brackets attached on the inverter. When
mounting the inverter with the heatsink outside
the enclosure,
depending on the panel cut
•
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.
