2.2 General Precaution
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.
2.3 Environment
Before installation, check that the environment meets following specifications:
Ambient temperature –10 °C to +50 °C (non-freezing)
Ambient humidity
90 % RH or less (non-condensing)
Atmosphere
Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)
Altitude
Maximum 1000 m above sea level for standard operation. After that derate by 3 % for every extra 500 m up to 2500 m (91 %)
Vibration
5.9 m/s² or less at 10 to 55 Hz (directions of X, Y, Z axes)
CAUTION
Install the inverter on a strong surface securely and vertically with bolts.
Leave enough clearances and take cooling measures.
Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity.
Install the inverter on a non-combustible surface.
