40 Planning the cabinet installation
Cabinet construction
Cabinet frame
Make sure...
The cabinet frame is sturdy enough to carry the weight of the drive components, control
circuitry and other equipment installed in it.
The cabinet protects the drive module against contact and meets the requirements for
dust and humidity. See data for relative humidity and contamination under Ambient
conditions on page 130.
Disposition of devices
Check that ...
The layout is spacious enough for easy installation and maintenance. There should be
sufficient space for cooling air flow, obligatory clearances, cables and cable support
structures.
See the layout example in Cooling and degrees of protection on page 44.
Grounding of mounting structures
Make sure ...
Proper grounding of
• all cross-members or shelves on which the drive system components are mounted
• the components through their fastening points to the installation base.
Note: It is recommended to mount the EMC filter (if present) and the drive module on the
same mounting plate.
The connecting surfaces are left unpainted.
