CHV180 series frequency inverter special for elevator Disassembly and installation
.11.
3.1 Environmental requirement
3.1.1 Temperature and Humidity
The ambient temperature is among-10 °C to 40 °C and the inverter has to derate by
4% for every additional 1 °C if the ambient temperature exceeds 40 °C. The
temperature cap is 50 °C.
Relative humidity of the air:
≦
90%. No condensation is allowed.
3.1.2 Altitude
The inverter can run at the rated power if the installation site is less than 1000m
(including 1000m) above the sea level. But it has to derate if the altitude exceeds 1000m.

3.1.3 Other environment requirements
The inverter can not bear fierce impact or shock. So the oscillation range should be less
than 5.88m/s
2
(0.6g), 10Hz~60Hz.
The inverter should keep away from the electromagnetic radiation source.
The inverter should keep away from water and condensation.
The inverter should keep away from contaminative air, such as corrosive gas, oil mist
and conductive dust.
The inverter should keep away from direct sunlight, oil mist, and steam and vibration
environment.
