SPAN-CPT User Manual Rev 8 9
WEEE Notice
If you purchased your SPAN-CPT product in Europe, please return it to your dealer or supplier at the end
of its life. The objectives of the European Community's environment policy are, in particular, to preserve,
protect and improve the quality of the environment, protect human health and utilise natural resources
prudently and rationally. Sustainable development advocates the reduction of wasteful consumption of
natural resources and the prevention of pollution. Waste electrical and electronic equipment (WEEE) is a
regulated area. Where the generation of waste cannot be avoided, it should be reused or recovered for
its material or energy. WEEE products may be recognized by their wheeled bin label ( ).

Lightning Protection Installation and Grounding
Procedures
What is the hazard?
A lightning strike into the ground causes an increase in the earth's potential which results in a high
voltage potential between the center conductor and shield of the coaxial cable. This high voltage
develops because the voltage surge induced onto the center conductor lags in time behind the voltage
surge induced onto the shield.
Hazard Impact
A lightning strike causes the ground potential in the area to rise to dangerous levels resulting in harm to
personnel or destruction of electronic equipment in an unprotected environment. It also conducts a
portion of the strike energy down the inner conductor of the coax cable to the connected equipment.
Actions to Mitigate Lightning Hazards
1. Do not install antennas or antenna coaxial cables outside the building during a lightning storm.
2. It is not possible to avoid over-voltages caused by lightning, but a lightning protection device may be
used to shunt a large portion of the transient energy to the building ground reducing the over-voltage
condition as quickly as possible.
3. Primary lightning protection must be provided by the operator/customer according to local building
codes as part of the extra-building installation.
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 10kV
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.

Only qualified personnel, electricians as mandated by the governing body in the country of
installation, may install lightning protection devices.
