3. Installation of Frequency Inverter
3.1 Installation environment
1.
The place with indoor vents or ventilation devices.
2.
The environment temperature shall be -10
℃
~40
℃
. If the temperature is over 40
℃
but less than 50
℃
,
better to take down the cover of frequency inverter or open the front door of cabinet to facilitate heat
dissipation.
3.
Try to avoid high temperature and wet place; the humidity shall be less than 90% without frost deposit.
4.
Avoid direct sunlight.
5.
Keep away from flammable, explosive and corrosive gas and liquid.
6.
No dust, floating fiber and metal particles.
7.
Install on the place without strongly vibration. And the vibration should be not over 0.6G, Especially pay
attention to far away from the punching machine, etc.
8.
Keep away from electromagnetic interference source.
3.2 Installation direction and space
In order to not affect the service life of frequency inverter and reduce its performance, note for its
installation direction and space and correctly fasten it.

Please install the frequency inverter vertically, to send out the heat upward, and pay attention to direction of
frequency inverter to avoid inversion.
If there are several units of frequency inverter installed, please install them side by side, do not to install up
and down.
