Precautions for Correct Use
Derating of the rated output current of the inverter may be required depending on the nor-
mal/light load mode selection, operating ambient temperature, side-by-side installation, and
carrier frequency settings.
Use the inverter in an appropriate environment according to A-1 Derating on page A-2.
Keep the inverter clear of heating elements such as a braking resistor or reactor.
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 (approximately 150°C or lower), provide the clearance
specified in the figure below during installation.
⚫
Standard installation
Provide a sufficient
clearance from upper
and lower wiring
ducts, etc. to prevent
the flow of cooling air
from being blocked.
⚫
Side-by-side installation
Provide a sufficient
clearance from upper
and lower wiring
ducts, etc. to prevent
the flow of cooling air
from being blocked.
