Important safety information
WARNING
To prevent loss of life or physical injury, observe the safety guidelines
in this section.
Power lines
Exercise extreme care when installing antennas near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
The Outdoor Unit (ODU) must be properly grounded to protect against lightning. It is
the user’s responsibility to install the equipment in accordance with national
regulations. In the USA, follow Section 810 of the
National Electric Code, ANSI/NFPA
No.70-1984 (USA). In Canada, follow Section 54 of the Canadian Electrical Code.
These codes describe correct installation procedures for grounding the outdoor unit,
mast, lead-in wire and discharge unit, size of grounding conductors and connection
requirements for grounding electrodes. Other regulations may apply in different
countries and therefore it is recommended that installation of the outdoor unit be
contracted to a professional installer.
