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