2.4 Cabinet design
The cabinet has been designed using the MNS cabinet system of ABB
The design consists of a skeletal frame to which
the outer panels are bolted to. Corrosion resistant
materials are used to protect the cabinet from cor-
rosion.
The basic elements of the frame are C-shaped steel
profiles with screw holes at a regular distance of 25
mm. The profiles are hot-dip zinc-coated. The
outer panels are bolted to the C-shaped profiles
with self-tapping screws. The panels are also pro-
tected by hot-dip zinc-coating.
The outside of the doors and the side panels are
painted to enhance the appearance of the cabinet.
The standard color is RAL 7035.
EMC has been achieved by applying an EMC sealing
around the doors, the rear and the side panels
(approximately 2 mm thick). The cabinet's inside
panels are not painted, because paint tends to
reduce the effectiveness of metallic bonding which
is important for successful EMC.
