If this device is not chosen as the primary lightning protection device, the device chosen must meet
the following requirements:
•
UL listed, or equivalent, in country of installation (for example, TUV, VDE and so on) for lightning
surge protection
• The primary device must be capable of limiting an incoming surge of 10 kV
5. The shield of the coaxial cable entering the building should be connected at a grounding plate at the
building's entrance. The lightning protection devices should have their chassis grounded to the same
ground near to the building's entrance.
6. The primary and secondary lightning protections should be as close to the building's entrance as
possible. Where feasible they should be mounted onto the grounding plate itself. See Figure 1,
Primary and Secondary Lightning Protection on page 13.
