Recommendations

To protect your equipment from lightning and surge damage, do the following:
• Install these TVSS devices as described in Chapter 7, "Surge Protective Devices" of the
Motorola Standards and Guideline for Communications Sites "R56" 68P81089E50 manual.
• Ground all RF transmission lines from the antenna structure to the shelter or building as
described in Chapter 4, "External Grounding," of the Motorola Standards and Guideline for
Communications Sites "R56" 68P81089E50 manual. Upon entering the building, all RF
transmission lines shall route through a coaxial RF-type TVSS (or Surge Protection Device).

General Electrostatic Discharge Recommendations

Electronic components, such as circuit boards and memory modules, can be extremely sensitive to
electrostatic discharge (ESD). Motorola recommends that an antistatic wrist strap and a conductive
foam pad be used when installing or upgrading the system.
If an ESD station is not available, wear an antistatic wrist strap. Wrap the strap around the wrist and
attach the ground end (usually a piece of copper foil or an alligator clip) to an electrical ground. An
electrical ground can be a piece of metal that literally runs into the ground (such as an unpainted
metal pipe) or the metal part of a grounded electrical appliance. An appliance is grounded if it has a
three-prong plug and is plugged into a three-prong grounded outlet.
NOTE: Do not use a computer as a ground, because it is not plugged in during installation.
September 9, 2011
All RF cables' outer shields must be grounded per Motorola
R56 requirements.
All RF cables shall be connected to a surge protection device
according to Motorola R56 documents. Do not connect Tx and
Rx RF cables directly to outside antenna.
