a regular size side panel to cover the extended cable management
brackets.
7 Mark the clearance on the floor as a dashed line.
8 Adjust the position of the template until all clearances are met.
For a raised floor with removable tiles, ensure the anchor hole markings
are at least 5 cm (2 in.) from the edge of a tile. This avoids drilling the
support of the tile that is under the floor.
9 Indelibly mark onto the floor the perimeter of the footprint template and all
oval openings that are to have an anchor. The perimeter is used later to
accurately position the frame. For zone 4 compliance, a minimum of 4
anchors must be used. The NEBS 2000 frame is best anchored at the 4
outer corners with the hardware indicated in the table "Frame anchoring
kits" (page 115). The position of each anchor should have been verified
as clear of obstruction in or under the floor in "Checking the floor"
(page 104).
10 From the table "Frame anchoring kits" (page 115), identify the anchor that
is appropriate to the type of floor or grade of installation.
11 Mark all 8 oval anchor openings on the floor. Although the frame provides
8 oval anchor openings, it is not necessary to use all unless the site has
been zoned for seismic tolerance. Zone 2 anchoring requires a minimum
of 4 anchors, while zone 3 requires 6 anchors (3 per half), and zone 4
requires all 8. All ovals are marked in case the drilling reaches an
obstruction imbedded in the floor (for example, construction rods or
rebar).
12 At the outside end (relative to the perimeter of the footprint) of each oval
opening, mark a center point as close to the end as the thickness of the
anchor. Anchor diameters are indicated in the table "Frame anchoring
kits" (page 115).
The other end of the oval opening is to be drilled only if the hole in the
outside end has reached an obstruction.
13 Keep the footprint template (insulator pad) with the frame because it is to
be used again when the frame is anchored to the floor.
14 Follow "Common procedure used for drilling any floor" (page 105).
