Design
In particular, make sure that the installation site is free from condensation.If condensed water
adheres to the Inverter's internal parts, the electronic components may short-circuit, causing
failure of the Inverter.In addition to avoiding condensation, avoid installing the Inverter under
direct sunlight.
Avoid an environment where the Inverter may be exposed to dust, gases (corrosive, explosive,
and/or flammable), grinding fluid mist, or salt.If a foreign object (e.g. dust) enters the Inverter,
it could result in failure of the Inverter.If using the Inverter in a dusty place, take appropriate
measures. (For example, place the Inverter in a closed panel.)
When several Inverters are installed in a panel and a ventilation fan is mounted in the panel,
be careful about the layout of the Inverters and the air intake apertures.Depending on the
layout, the Inverter's cooling effect may deteriorate, resulting in an increase in the ambient
temperature.
