(6) Mounting
Position
Mount the inverter in a vertical position using screws or bolts. The mounting surface should
also be free from vibration and can easily hold the weight of the inverter.
Fig. 2- 2 Mounting Position
(7) Ventilation within an Enclosure
If you are installing one or more inverters in an enclosure a ventilation fan should be installed.
Below is a guide to the positioning of the fan to take the airflow into consideration. The
positioning of inverter, cooling fans and air intake is very important.
If these positions are wrong, airflow around the inverter decreases and the temperature
surrounding the inverter will rise. So please make sure that the temperature around is within
the limit of the allowable range.

(8) External cooling of inverter
It is possible to install the inverter so that the heatsink is outside of the back of the enclosure.
This method has two advantages, the cooling of the inverter is greatly increased and the size
of the enclosure will be smaller.
To install it with the heatsink outside of the enclosure, a metal fitting option is required to
ensure heat transfer. Do not install in a place where water, oil, mist, flour, and/or dust etc. can
come in contact with the inverter as there are cooling fans fitted to the heatsink.
