3.3.8 General Power Guidelines and Requirements
System certification was completed using shielded cables. To prevent emission problems, use only
shielded cables. Do not substitute other cable types.
• Ensure equipment is positioned 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. Maintenance
loops are recommended.
• 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. Cable ties should be loose enough
to allow adjustment.
• Verify that all cables are properly labeled to match System-specific configuration documentation
provided by Motorola.
• Ensure that cables do not exceed the minimum bend radius as outlined in the Motorola
Standards
and Guidelines for Communication Sites
manual.
For more information on cabling guidelines, see the documentation supplied with components from
each equipment manufacturer.
Use only Category 5 Shielded Twisted Pair (or higher) for cabling Ethernet connections. Motorola
has engineered this system to meet specific performance requirements. Using other cabling and
connectors may result in unpredictable system performance or catastrophic failure.
3.3.8 General Power Guidelines and Requirements
Follow the guidelines in the Motorola
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.
Electrical installation work shall be carried out in accordance with the current edition of the NFPA 70 and local
building codes. Where required, only a qualified and licensed electrician shall be used for all electrical installations.
3.3.8.1 General AC Power Guidelines and Requirements
The Motorola
Standards and Guidelines for Communication Sites
manual defines the guidelines and requirements
for cabinets and racks which house equipment that requires AC power input. Some of the guidelines and
requirements are as follows:
• The cabinet or rack is designed to accept 120/240 V, single-phase power with an amperage service size as
required by the electronic equipment.
• Cabinets and racks serviced by commercial power must be equipped with a nationally recognized test
laboratory (NRTL) certified power distribution module that contains a main circuit breaker or individual
circuit breakers of the correct size as required for the electronic equipment or specified by the customer.
• A decal showing an electrical schematic of the power wiring is affixed to the inside surface of the cabinet.
