If the inverter is installed in a control panel, take into consideration dimensions and ventilation to keep
the ambient temperature within the range of the specifications.
To allow heat dispersion from inside the inverter (approx. 150°C or lower), provide the clearance
specified in the figure below during installation.

Ambient Temperature Control
To ensure reliable operation, use the inverter in an environment subject to minimal temperature rise as
much as possible.
If you install a ventilation fan in a control panel where several inverters are installed, be careful about
the layout of the inverters and the air intake and ventilation apertures.
Remember that poor air circulation around inverters causes an internal temperature rise, which may
inversely affect the internal components of the inverters.
