Equipment Grounding and Lightning
Protection
WARNING Consult the local electricity professionals for the local grounding
requirements. The customer is responsible for supplying grounding
cables, rods, clamps, power cables, long distance signal cables, and
conduits for cables.
With mast installations, equipment grounding and lightning
protection must be done separately. The main principles are as follows:
- Proper equipment grounding is required for personnel safety and for
equipment protection. A piece of equipment is grounded by
connecting its metal structures and electrical equipment to an external
buried ground rod. Individual site requirements may dictate changes in
the procedures described in this manual. Changes are permissible as
long as protection equivalent to the original requirements is provided
for the system.
WARNING Failure to provide proper grounding may result in personnel injury or
death from electrical shock and may severely damage the equipment.
WARNING Lightning protection is required to prevent personnel injury and
equipment damage due to direct lightning strikes and lightning-induced
current surges.
- The materials used in the manufacture of the grounding systems must
be chosen to prevent them from forming an electrolytic couple. It is
recommended that you use copper (Cu).
