Chapter 3 Environment & Installation
3.1 Environment
Installation environment has a direct effect on the correct operation and the life expectancy of the
inverter, Install the inverter in an environment complying with the following conditions:
Protection
Protection
class
IP20 Open Type
Suitable environment
Operating
temperature
-10~40°C (-10~50°C with fan) (non-freezing)
If several inverters are installed in the same control panel, ensure
adequate spacing and provide the necessary cooling and ventilation for
successful operation.
Storage
temperature
-20~60°C
Relative
Humidity
Max 95% (without condensation)
Altitude
Altitude：Below 1000m (3281ft)
It is required to reduce 2% of inverter
rated current at each additional
100m. The maximum altitude is
3000m
Vibration
Frequency: 10Hz - 150Hz - 10Hz
Amplitude(0.3mm): 10Hz ≦f ≦57Hz
Acceleration(2G): 57Hz ≦f ≦150Hz
(According to IEC60068-2-6 standard)
Installation site
Install in an environment that will not have an adverse effect on the operation of the unit
and ensure that there is no exposure to areas such as that listed below:-
Direct sunlight, Rain or moisture
Oil mist and salt
Dust, lint fibres, small metal filings and corrosive liquid and gas
Electromagnetic interference from sources such as welding equipment
Radioactive and flammable materials
Excessive vibration from machines such as stamping, punching machines
