2.3 Connecting Utility Power
ONLY qualifi ed personal should connect the utility power. Power must be connected in
compliance with local electrical codes, and common safety practices must be observed.
WARNING!
• Connection to utility power may need to be approved by the local utility before installing the
enclosure.
• Your local authority may require that a service disconnect switch (UL listed) be provided by the
installer and be connected between the power source and the enclosure.
ATTENTION:
Strike (Lightning) Ground
Lightning strikes, grid switching, or other aberrations on the power line and/or communications cable have the
potential to cause high-energy transients which can damage the powering or communitations systems. Without a low-
impedance path to ground, the current, when traveling through wires of varying impedance, produce damaging high
voltage. The most viable method available to protect the system from damage is to divert these unwanted high-energy
transients along a low-impedance path to ground. A low-impedance path to ground prevents these currents from
reaching high voltage levels and posing a threat to equipment. The single-point grounding system provides a low-
impedance path to ground, and the key to its success is the proper bonding of the ground rods, so the components of
the grounding system appear as a single point of uniform impedance. Alpha recommends the use of a surge arresting
device electrically bonded to the grounding system.
All ground rod connections must be made by means of a listed grounding clamp suitable for direct burial or
exothermically welded.
Low impedance grounding is mandatory for personnel safety and critical for the proper
operation of the cable system .
