2.1.5.4 Prepare the Mounting Location – R8
The ACB530 should only be mounted where all
of the requirements defined in “Preparing for
Installation” are met.
Frame size R8 has mounting holes inside the
enclosure base. See “UL Type/NEMA 1&12, Floor
Mount Enclosure Mounting Dimensions”.
Where it is not possible to use either mounting hole
at the back of the base, use an L-bracket at the top
of the enclosure to secure the cabinet to a wall or to
the back of another enclosure. Bolt the L-bracket to
the enclosure using the lifting lug bolt hole on the top
of the enclosure.
