System Grounding and Surge Protection
28 GHz SONET OC-3 IFU Installation - R1.0 1-3
System Grounding and Surge Protection
The IFU grounding system has two conceptually distinct, but electrically
interconnected functional subsystems, for connection to “earth ground.” The
two functional subsystems are:
n Earth ground (complies with the National Electrical Code (NEC) for
equipment grounding systems).
n Surge protection.
Earth Ground
The IFU has an external electrical interconnection point for connecting the
IFU ground subsystems to earth ground.
Surge Protection
The sole purpose of surge protection is to transport lightning-related currents
to the earth ground. During site installation, surge suppression devices are
installed inline with the power and alarm conductors to assist in protecting
equipment.
