Planning the cabinet assembly

What this chapter contains

This chapter guides in planning the installation of a drive module into a user-defined
cabinet. The issues discussed are essential for safe and trouble-free use of the drive
system.
Note: The installation examples in this manual are provided only to help the installer
in designing the installation. The installation must always be designed and made
according to applicable local laws and regulations. ABB does not assume any
liability whatsoever for any installation which breaches the local laws and/or other
regulations.

Cabinet construction

The cabinet frame must be sturdy enough to carry the weight of the drive
components, control circuitry and other equipment installed in it.
The cabinet must protect the drive module against contact and meet the
requirements for dust and humidity (see chapter

Disposition of the devices

For easy installation and maintenance, a spacious layout is recommended. Sufficient
cooling air flow, obligatory clearances, cables and cable support structures all
require space.
For layout examples, see section

Grounding of mounting structures

Make sure all cross-members or shelves on which components are mounted are
properly grounded and the connecting surfaces left unpainted.
Note: Ensure that the modules are properly grounded through their fastening points
to the installation base.
