Checking and Controlling the Installation Site

Install the Inverter in the installation site described below and maintain optimum conditions.

Installation Site

Install the Inverter under the following conditions in a pollution degree 2 environment.
Type
NEMA1 / IP20
IEC IP00
Protection covers are attached to the top and bottom of the Inverter. Be sure to remove the protection covers
before installing a 200 or 400 V Class Inverter with an output of 18.5 kW or less in a panel.
Observe the following precautions when mounting the Inverter.
Install the Inverter in a clean location which is free from oil mist and dust. It can be installed in a totally
•
enclosed panel that is completely shielded from floating dust.
When installing or operating the Inverter, always take special care so that metal powder, oil, water, or other
•
foreign matter does not get into the Inverter.
Do not install the Inverter on combustible material, such as wood.
•
Install the Inverter in a location free from radioactive materials and combustible materials.
•
Install the Inverter in a location free from harmful gasses and liquids.
•
Install the Inverter in a location without excessive oscillation.
•
Install the Inverter in a location free from chlorides.
•
Install the Inverter in a location not in direct sunlight.
•

Controlling the Ambient Temperature

To enhance the reliability of operation, the Inverter should be installed in an environment free from extreme
temperature increases. If the Inverter is installed in an enclosed environment, such as a cabinet, use a cooling
fan or air conditioner to maintain the internal air temperature below 45°C.

Protecting the Inverter from Foreign Matter

Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Always remove the cover from the Inverter after the completion of the installation. Otherwise, ventilation will
be reduced, causing the Inverter to overheat.
