1.3 Usage environment and Storage environment
This section provides precautions when handling inverters, e.g. precautions for installation environment and
storage environment.
1.3.1 Usage environment
Install the inverter in an environment that satisfies the requirements listed in Table below.
Environmental Requirements
5 to 95% (No condensation)
Atmosphere
The inverter must not be exposed to dust, direct sunlight, corrosive gases, flammable gases, oil
mist, vapor or water drops. Pollution degree 2 (IEC/EN 60664-1) (*1)
The atmosphere can contain a small amount of salt. (0.01 mg/cm
2
or less per year)
The inverter must not be subjected to sudden changes in temperature that will cause condensation
to occur.
Altitude 1,000 m max. (*2)
Atmospheric pressure 86 to 106 kPa
Vibration
9.8 m/s
2
: 9 to less than 20 Hz
2 m/s
2
: 20 to less than 55 Hz

(*1) Do not install the inverter in an environment where it may be exposed to lint, cotton waste or moist dust or dirt which will clog the heat sink
of the inverter. If the inverter is to be used in such an environment, install it in a dustproof panel of your system.
(*2) If you use the inverter in an altitude above 1000 m, you should apply an output current derating factor as listed in the table below.
Altitude
1000 m or
1000 to 1500 m 1500 to 2000 m 2000 to 2500 m 2500 to 3000 m
Output current derating factor
