The NICE3000
new

mounting method. It is fastened onto the support with four screws xed into the four mounting holes, as shown in the
following gure.
The plastic structure and sheet metal structure have the same mounting method.

It is forbidden to fasten only the upper two screws, because the controller may fall and be damaged due to
uneven force after long-time running. Ensure that all the four screws are fastened.
Pay attention to the following points when designing the control cabinet:
●
The temperature inside the cabinet must not rise to 10°C higher than the temperature outside the
cabinet.
●
A closed control cabinet must be congured with a fan (or other air cooling device such as air
conditioner) to ensure air circulation.
●
The air from the fan must not blow directly to the drive unit because this easily causes dust
adhesion and further a fault on the drive unit.
