8.2 Mounting Cabinets on the Concrete Floor

To mount B68 cabinets on the concrete floor, use the integrated anchor strips to fasten the

cabinet feet. The height of the feet is adjustable for installation on the floor that is not flat.

Caution:

The feet are insulated, and the anchor strips include insulating units. Correctly install

the insulating units to insulate the equipment from the earth ground before it is

grounded.
