4. To ensure compliance with clause 7 "Connection to Cable Distribution Systems" of EN 60950-1, Safety for
Information Technology Equipment, a secondary lightning protection device must be used for in-building
equipment installations with external antennas. The following device has been approved by NovAtel Inc.:
Polyphaser - Surge Arrestor DGXZ+24NFNF-A
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 to 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, mount onto the grounding plate itself (refer to the figure below).
