3.1 Environment
The environment will directly affect the proper operation and life span of the AC Drive. To ensure that the AC Drive
will give maximum service life, please comply with the following environmental conditions:
Protection
Protection Class:
IP20 / NEMA 1 (Depending on models)
Operating
Temperature:
IP20 / NEMA 1 type:
Inside: -10°C - +50°C (14-122 °F)
Outside: -10°C - +40°C (14-104 °F)
If several AC Drives are placed in the same control panel, provide additional cooling and
ventilation to maintain ambient temperatures below 40°C (104 °F)
Storage
Temperature:
-20°C - +60°C (-4 -140 °F)
Humidity:
95% non-condensing
Relative humidity 5% to 95%, free of moisture.
(Follow IEC60068-2-78 standard)
Altitude:
< 1000m (3,281 ft.)
Installation Site:
Avoid exposure to rain or moisture.
Avoid direct sunlight.
Avoid oil mist and salinity.
Avoid corrosive liquid and gas.
Avoid dust, lint fibers, and small metal filings.
Keep away from radioactive and flammable materials.
Avoid electromagnetic interference (soldering machines, power machines).
Avoid vibration (stamping, punching machines etc.).
Add a vibration-proof pad if the situation cannot be avoided.
Shock:
Maximum acceleration: 1G (9.8m/s²), for <20Hz
Maximum acceleration: 0.6G (5.88m/s²), for 20 - 50Hz (IEC60068-2-6 standard)
