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.
Using the correct power supply
Always use the Cambium Power over Ethernet injector unit (PoE power supply) or
Powered Indoor Unit (PIDU Plus) to power the ODU. Failure to use the correct power
supply could result in equipment damage and will invalidate the safety certification and
may cause a safety hazard.
