Cabinet assembly planning

What this chapter contains

This chapter guides in planning the installation of a converter module into a user-
defined cabinet. The issues discussed are essential for the safe and trouble-free use
of the drive system.

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 converter 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, cable support structures all require
space.
The control boards must not be installed near a main circuit or hot parts.
For layout examples, see chapter

Grounding of mounting structures

Make sure any cross-members or shelves on which components are mounted are
properly grounded and the connecting surfaces left unpainted.

Busbar material and joints

Tin-plated copper is recommended but aluminium can also be used.
Before joining aluminium busbars, remove the oxide layer and apply suitable anti-
oxidant joint compound.
