Installation Environment
• Increased ambient temperatures will shorten the life of the Inverter.
• Keep the Inverter away from heating elements (such as a braking resistor, DC reactor, etc.).
If the Inverter is installed in an enclosure, keep the ambient temperature within the range of the
specifications, taking dimensions and ventilation into consideration.
• When several 3G3RX models are installed in an enclosure and a ventilation fan is mounted in the
enclosure, be careful about the layout of the Inverters and the air intake apertures.
Depending on the internal layout of the panel, the Inverter's cooling effect may deteriorate,
resulting in an increase in ambient temperature.
Also, use thorough caution in making sure that the Inverter's ambient temperature is within the
allowable operating temperature range.
• Before installing the Inverter, place a cover over all the ventilation openings to shield them from
foreign objects.
After completing the installation process, be sure to remove the covers from the Inverter before
operation.
• Below is the heat radiation according to the Inverter capacity.
