1.3 Installation Considerations
Inverters are composed of various precision, electronic devices, and therefore the
installation environment can significantly impact the lifespan and reliability of the
product. The table below details the ideal operation and installation conditions for the
inverter.
Heavy load: -10–50℃, Normal load: -10–40℃
Less than 95% relative humidity (no condensation)
An environment free from corrosive or flammable gases, oil residue,
or dust
Operation
altitude/oscillation
Lower than 3,280 ft (1,000 m) above sea level, less than 1G (9.8
m/sec
2
)
(Apply derating of 1% at a time on voltage/output current for every
100 m increase starting from 1,000 m, going up to a maximum of
4,000m)
* The ambient temperature is the temperature measured at a point 2” (5 cm) from the
surface of the inverter.
