Alternative 2 – Using the holes inside the cabinet
The cabinet can be fastened to the floor using the fastening holes inside the cabinet,
if they are accessible. The recommended maximum distance between the fastening
points is 800 mm (31.5").
If there is not enough working space behind the cabinet for mounting, replace the
lifting lugs at the top with L-brackets (not included) and fasten the top of the cabinet
to the wall.
