1.3 Precautions for Using Inverters
This section provides precautions in introducing inverters, e.g. precautions for installation environment, power
supply lines, wiring, and connection to peripheral equipment. Be sure to observe those precautions.
1.3.1 Usage environment
Install the inverter in an environment that satisfies the requirements listed in Table 1.3-1.
Table 1.3-1 Usage Environment
Item Specifications
Site location Indoors
Ambient temperature Standard（Open Type）
-10 to +50°C (14 to 122°F) (HHD/HND spec.) (Note 1)
-10 to +40°C (14 to 104°F) (HD/ND spec.)
NEMA/UL Type1
-10 to +40°C (14 to 104°F) (HHD/HND spec.)
-10 to +30°C (14 to 86°F) (HD/ND spec.)
Relative humidity 5 to 95% RH (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 (IEC60664-1) (Note 2)
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 form.
Altitude
1,000 m (3,300 ft) max. (Note 3)
Atmospheric pressure 86 to 106 kPa

(Note 1) When inverters are mounted side-by-side without any clearance between them (FRN0011E2■-7 /
FRN0115E2■-2 / FRN0072E2■-4 or below), the ambient temperature should be within the range
from -10 to +40°C.
(Note 2) 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.
(Note 3) If you use the inverter in an altitude above 1,000 m (3,300 ft), you should apply an output current derating
factor as listed in Table 1.3-2.
Table 1.3-2 Output Current Derating Factor in Relation to Altitude

1,000 m or lower (3,300 ft or lower)
1.00
1,000 to 1500 m (3,300 to 4,900 ft)
0.97
1,500 to 2,000 m (4,900 to 6,600 ft)
0.95
2,000 to 2,500 m (6,600 to 8,200 ft)
0.91
2,500 to 3,000 m (8,200 to 9,800 ft)
