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
Protection Class IP20 and IP54
Protection Class IP00
Protection covers are attached to the top and bottom of the NEMA 1 and IP00 Inverters. Be sure to remove the
top cover before operating a 200 or 400 V Class Inverter with an output of 18.5 kW or less inside 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 enter 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 without in direct sunlight.
The IP54 Inverters provide protection from non-conductive dust and splashing water from all directions.
•
Install the Inverter indoors in a heated and controlled environment to avoid condensation inside the
Inverter.
Keep any water or dust outside of the IP54 Inverter when wiring.
•

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 IP00 or NEMA 1 Inverter is installed in an enclosed environment, such as a box,
use a cooling fan or air conditioner to maintain the internal air temperature below 45°C.
When the IP54 Inverter is installed in a environment with low temperatures or when the Inverter remains
switched off for a long time, condensation may occur inside the Inverter. In that case additional heaters may
effectively prevent condensation inside the inverter.

Protecting the IP00 or NEMA 1 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 completing installation. Otherwise, ventilation will be
reduced, causing the Inverter to overheat.
