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.
