4.1.4 Concrete slab
Cast-in-place or pre-cast concrete slabs can be used.
Place the enclosure on the concrete slab. Use the enclosed Hilti HSL heavy-duty expansion anchor bolts or
approved equivalents to secure the enclosure. Follow the specific recommendations from the fastener
manufacturer to ensure that the securing device achieves its full structural capacity. Take into account the
embedment depth and clear edge distances. Refer to the following figure.
Alternate mounting systems that are not provided directly with the enclosure must be reviewed by a registered
professional engineer that is qualified to practice within the jurisdiction where the enclosure is being installed.
An alternate mounting system could for example use a chemical anchoring system such as Hilti’s HY150 for
concrete or HY20 for masonry along with suitable threaded rods and inserts from the manufacturer. Follow the
manufacturer’s recommendations to determine the spacing and placement of the threaded rods.
The supporting structure must be designed to support a fully equipped enclosure. The concrete slab and any
existing structures must be properly reinforced to support the floor loading. The mounting site must be designed
and installed in accordance with local building practices and codes.
