In applications where flush-mount expansion anchors are not preferred or
acceptable, then wedge-type stud anchors may be used.
acceptable, then wedge-type stud anchors may be used.
•
All concrete anchors shall be zinc-plated carbon steel for standard
applications, galvanized steel for mildly humid or corrosive environments, and
yellow zinc or stainless steel for humid, highly corrosive, or acidic
environments. Minimum bolt diameter shall be 10 mm (0.375 in.) with 12 mm
(0.5 in.) preferred. Anchor embedment depth should be at least 76 mm (3 in.)
to provide good tensile and shear strength. Follow manufacturer's instructions
for depth reduction when rebar is encountered. A heavy-duty washer should
be part of the anchor assembly to ensure the equipment is secure.

3.3.1.4 Isolated
Mounting
Isolated mounting is recommended to prevent a second electrical path to ground
through the concrete floor, and is required for the installation of certain
equipment. In these cases expansion anchors are inserted into the concrete
floor. However, isolation of the equipment rack is ensured using an insulating
plate and hardware. If the installation is in an earthquake zone, additional
anchors are used.

NOTE: Motorola equipment frames are always required to use, and are shipped
with, isolating washer and bolt assemblies, and have separate insulating
mounting plates. Refer to the Motorola document 68P09226A18 Frame Mounting
Guide for more information.

3.3.1.5
Mounting on Wood or Fiberglass Floors
Appropriately sized lag bolts shall be used for mounting on wood or fiberglass
floors. If the underside is accessible and the floor stability is questionable, then
thru-bolting may be desirable.
floors. If the underside is accessible and the floor stability is questionable, then
thru-bolting may be desirable.
RFN recommends mounting non-racked ancillary equipment on a "C-channel"
type of mounting track where possible. This provides for easy cleaning and some
isolation in the case of standing water. Another benefit of installing non-rack
mounted equipment off the floor is that the weight is distributed across the floor.
In these cases, C-channel type mounting provides multiple floor anchor points
where the equipment provides only four to six anchor points.

When mounting racks to raised computer floors, 0.5 in. (13 mm) minimum
diameter allthread rod and flush-mount expansion anchors shall be used to
anchor to the concrete subfloor. When mounting consoles to a raised floor,
0.375 in. (10 mm) minimum allthread rod and hardware shall be used for
anchoring. Mounting arrangement shall be in accordance with mounting kit
manufacturer's instructions.
