5. Operating Environment-Air

Install the Inverter avoiding any place that has dust, corrosive gas, explosive gas, combustible gas,
mist of coolant and sea damage.

6. Mounting Position

Mount the Inverter in a vertical position using screws or bolts. The surface you mount onto should
also be free from vibration and can easily hold the weight of the Inverter.

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 out of the back of the enclosure.
This method has two advantages, cooling of the inverter is greatly increased and the size of the
enclosure will be smaller.
To install it with the heatsink out 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 dust etc can come in contact
with the inverter as there are cooling fans fitted to the heatsink.
