Rack Installation
Positioning and Securing Racks
Installing Rack in a Suite
From the site survey, confirm the position of the CT Rack(s). If the racks are to be
positioned in a suite, metalwork will be required to secure it to the overhead structure.
Either a proprietary system or fabricated steelwork will be required - see site survey.
Manoeuvre the racks into position.
Securing Rack Base
Using the base of the rack as a template, mark the floor locating positions through the
cutouts in the Rack Frame. Using a 13mm diameter drill bit, drill four holes to a depth of
approximately 25mm. Position the rack over the four holes and screw the four (supplied)
M12 screws through washers to secure the rack base. If the rack is cabled from under the
floor the access holes are required through the floor beneath the rack base.
Securing Rack Base
Warning: These screws are provided as locating pins only and must be used in
conjunction with the overhead steelwork and not as the only method for securing the rack.
Temporarily secure the rack to adjacent racks or steelwork until the overhead support is in
place.
Securing the rack using overhead Ironwork
Assemble the overhead steelwork as required and secure the rack to the overhead
structure using suitable fixings in compliance with local requirements. Remove all burrs
and sharp edges.
