Figure 2. Central Terminal Rack.

Using the base of the rack as a template, mark the floor locating positions

through the welded nuts in the Rack Frame. Using a 13mm. diameter drill bit,

drill four holes to a depth of approximately 25mm. Position the CT rack over

the four holes and screw the four (supplied) M12 screws through the rack base.

Warning: These screws are provided as locating pins only and must be

used in conjunction with the overhead steelwork and not as an alternative

method for securing the rack.

Temporarily secure the rack to adjacent racks or steelwork until the overhead

support is in place.
