Chapter 3 Ambient Environment And Installation
3.1 Environment
The installing environment of the inverter directly affects its functions and the service
life. Therefore, the installation environment must meet the following conditions:
Protection
Protection
Class
IP20/NEMA 1, IP00
Applicable environment
Operating
Temperature
-10~40 (℃ With the dust-protection cover open, the applicable operation
temperature (-10~50 )) (℃ full load) can reach maximum of 60℃. But it is
required to de-rating 2% of the rated current for increasing one degree.
For multiple inverters installed side by side in the plate, please pay
attention to the placement to facilitate heat radiating.
Storage
Temperature
-20~70℃
Humidity
RH should be 5% to 95%, free of condensation or water droplets.
(Follow IEC60068-2-78 standard)
Shock
Maximum acceleration: 1.2G (12m/s
2
), from 49.84 to 150 Hz
Displacement amplitude : 0.3mm (peak value), from 10 to 49.84 Hz
(Follow IEC60068-2-6 standard)
Installation site
The product shall be installed in the environment for easy operation, avoiding to be
exposed to the following environments:
¾ Avoid direct sunlight
¾ Avoid rain drops or wet environment
¾ Avoid oil mist and salt erosion
¾ Avoid corrosive liquid and gas
¾ Avoid dust, lint fibers, and small metal filings.
¾ Avoid electromagnetic interference (soldering machine, power machine)
¾ Keep away from radioactive and flammable materials
¾ Avoid vibration (punch). Please add a vibration-proof pad to reduce vibration if it can
not be avoided
