Lightning protection zones
Use the rolling sphere method as shown in Figure 4 to determine where it is safe to mount the
equipment. An imaginary sphere, typically 50 meters in radius, is rolled over the structure. Where the
sphere rests against the ground and a strike termination device (such as a finial or ground bar), all the
space under the sphere is considered to be in the zone of protection (Zone B). Similarly, where the
sphere rests on two finials, the space under the sphere is considered to be in the zone of protection.
Figure 4: Rolling sphere method to determine the lightning protection zones
Assess locations on masts, towers, and buildings to determine if the location is in Zone A or Zone B:
l
Zone A: In this zone a direct lightning strike is possible. Do not mount the equipment in this zone.
l
Zone B: In this zone, direct EMD (lightning) effects are still possible, but mounting the equipment
in this zone significantly reduces the possibility of a direct strike. Mount the equipment in this
zone.
Warning
Do not mount the equipment in Zone A. Mounting the equipment in Zone A
poses risk to the equipment, structures, and human lives.
Electromagnetic Compatibility (EMC) compliance
ePMP complies with European EMC Specification EN301 489-1 with testing carried out to the detailed
requirements of EN 301 489-17.
The EMC specification type approvals that is granted for ePMP are listed under Table 1.
