the local laws and/or other regulations. Furthermore, if the recommendations given by ABB

Cabinet construction
Basic requirements for the cabinet construction are listed below. Make sure that:
• cabinet frame is sturdy enough to carry the weight of the components, control circuitry
and other equipment installed in it
• cabinet protects the modules against contact and agrees with the requirements for dust
and humidity
• 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
• 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.
