7 Secure the cabinet or rack to the site floor with the locally procured mounting hardware.
IMPORTANT: If securing the cabinet or rack to a concrete floor, use 1/2-inch grade 8
bolts with anchors.
3.3.6
General Bonding and Grounding Requirements
Cabinets and racks include a Rack Grounding Bar (RGB) with the capacity to terminate numerous
ground wires. Attach equipment added to the cabinet or rack to the ground bar using solid or stranded
6 AWG copper wire.
The RGB uses dual-hole lugs to terminate ground wires. The minimum number of dual-hole
attachments is system-dependent and specified by the customer. This bar provides electrical continuity
between all bonds and ground wire with a current-carrying capacity equal to or exceeding that of a 6
AWG copper wire.
See the Motorola Solutions Standards and Guidelines for Communication Sites manual for more
information on proper bonding and ground at a site.

General Cabling Requirements
Diagrams for cabling are typically included in the system-specific configuration documentation Motorola
Solutions provides.
Also see the Motorola Solutions Standards and Guidelines for Communication Sites manual for cabling
standards.
IMPORTANT: System certification was completed using shielded cables. To prevent emission
problems, use only shielded cables. Do not substitute other cable types.
•
Position the equipment to avoid excessive tension on cables and connectors. Cables must be loose
with absolutely no stress on the connectors. Careful cable routing and securing the cables with tie
wraps (or other devices) is one way to provide this protection. Set up preventive maintenance loops.
•
Dress the cables neatly using cable ties. Do not tighten the cable ties until you are sure that the
required service length and bend radius requirements are met. Leave cable ties loose enough to
allow adjustment.
•
Verify that all cables are properly labeled to match System-specific configuration documentation
Motorola Solutions provided.
•
Ensure that cables do not exceed the minimum bend radius as outlined in the Motorola Solutions
Standards and Guidelines for Communication Sites manual.
CAUTION: Use only Category 5 Shielded Twisted Pair (or higher) for cabling Ethernet
connections. Motorola Solutions has engineered this system to meet specific performance
requirements. Using other cabling and connectors may result in unpredictable system
performance or catastrophic failure.
NOTICE: For more information on cabling guidelines, see the documentation supplied with
components from each equipment manufacturer.

General Power Guidelines and Requirements
See the Motorola Solutions Standards and Guidelines for Communication Sites manual for information
on providing electrical service, power budgeting, selecting batteries, and other topics for supplying
power at the site.
