Safety
Warning
To prevent loss of life or physical injury, observe the following safety guidelines. In no
event shall Cambium Networks be liable for any injury or damage caused during the
installation of the Cambium 450 Platform Family. Ensure that only qualified personnel
install a 450 Platform link.
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
Power supply
Always use one of the Cambium 450 Platform Family power supply units (PSU) to power the ODU.
Failure to use a Cambium supplied PoE could result in equipment damage and will invalidate the
safety certification and may cause a safety hazard.
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
the requirements of the National Electrical code NFPA 70-2005 and 780-2004
Installation of
Lightning Protection Systems
. 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.
Powering down before servicing
Always power down and unplug the equipment before servicing.
