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 they should be mounted onto the grounding plate itself. See also
Figure 1 on Page 10.
