Attaching the cabinet
Refer to the cabinet manufacturer's instructions.
WARNING!
Do not attach the cabinet by electric welding. ABB does not assume any liability
for damages caused by electric welding as the welding circuit can damage
electronic circuits in the cabinet.
Cabinet placement on a cable duct
Note the following when you plan to place the cabinet on a cable duct:
• The cabinet structure must be sturdy enough. If the whole cabinet base is not
supported from below, the cabinet weight will lie on the sections that the floor
carries.
• Equip the cabinet with a sealed bottom plate and cable entries to ensure the
degree of protection and to prevent the cooling air flow from the cable duct into
the cabinet.

Cabinet heating elements
Use a heater if there is a risk of condensation in the cabinet. Although the primary
function of the heater is to keep the air dry, it may also be required for heating at low
temperatures.
