The bus capacitor discharge time is 10 minutes. Before starting wiring or inspection, switch power OFF, wait for more than 10
minutes, and check for residual voltage between terminal P/+ and N/- with a meter etc., to avoid a hazard of electrical shock.
Environment
Before installation, check that the environment meets the following specifications.
Surrounding air
-10°C to +50°C (non-freezing)
temperature
Ambient humidity
90% RH or less (non-condensing)
-20°C to +65°C 
Storage temperature
Ambience
Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)
Maximum 1000m for standard operation. 
Altitude, vibration
5.9m/s

Temperature applicable for a short time, e.g. in transit.

For the installation at an altitude above 1000m up to 2500m, consider a 3% reduction in the rated current per 500m increase in altitude.
Note
 Install the inverter on a strong surface securely and vertically with bolts.
 Leave enough clearances and take cooling measures.
