Contents of this chapter
This chapter contains generic cabinet planning instructions applicable to any user-defined
cabinet system. The topics discussed are essential for the safe and trouble-free use of the

Limitation of liability
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. Furthermore, if the recommendations given by ABB
are not followed, the drive may experience problems that the warranty does not cover.
Cabinet construction
Basic requirements for the cabinet construction are listed below. Make sure that:
• the cabinet frame is sturdy enough to carry the weight of the components, control circuitry
and other equipment installed in it
• the cabinet protects the modules against contact and agrees with the requirements for
dust and humidity
• the cabinet frame and doors are strong enough to provide adequate protection against
flames or pressure blast originating from inside the cabinet in case of arc flash or similar
failure
• the cabinet has air inlet and outlet gratings that allow free flow of cooling air through
the modules inside the cabinet.
￭ Disposition of the devices
Plan a spacious layout to ensure easy installation and maintenance. Sufficient cooling air
flow, obligatory clearances, cables and cable support structures all require space.
