3.1 Mechanical Installation
3.1.1 Installation environment
1) Ambient temperature: The ambient temperature exerts great influences on the service life of the inverter
and is not allowed to exceed the allowable temperature range (-10
℃
to 50
℃
).
2) The inverter should be mounted on the surface of incombustible articles, with sufficient spaces nearby
for heat sinking. The inverter is easy to generate large amount of heat during the operation. The inverter
should be mounted vertically on the base with screws.
3) The inverter should be mounted in the place without vibration or with vibration of less than 0.6G, and
should be kept away from such equipment as punching machine.
4) The inverter should be mounted in locations free from direct sunlight, high humidity and condensate.
5) The inverter should be mounted in locations free from corrosive gas, explosive gas or combustible gas.
6) The inverter should be mounted in locations free from oil dirt, dust, and metal powder.

Single Unit Installation: When the inverter power is not higher than 15kW, the A size can be omitted. When
the inverter power is higher than 15kW, the A size should be higher than 50mm.
Installation of Upper and Lower Parts: When installing the upper and lower parts of the inverter, the
insulating splitter is required.
