Product Safety Information
Warning
To prevent loss of life or physical injury, observe the safety
guidelines in this section.
1. Ensure that the Outdoor Unit (ODU) and the structure on which it is mounted is capable of
withstanding the maximum wind speeds at a proposed site.
2. Ensure the equipment is not powered ON during installation. Always disconnect equipment from its
power source before servicing.
3. Harmful levels of RF radiation are present close to the antenna when the transmitter is ON.
4. For observing the minimum safe distance limit of cnRanger products refer to
5. Ensure that the equipment is installed in a position avoiding any radiation hazard to humans.
6. Exercise extreme care when working at heights. Observe national ‘working at heights’ regulations.
Use trained ‘competent’ staff.
7. Exercise extreme care when working near power lines.
8. Always use a qualified electrician to install cabling.
9. The cnRanger equipment must be properly grounded.
10. Always use the specified Cambium cnRanger platform Power Supply Units (PSU) to power ON the
equipment. Failure to use the specified Cambium supplied power equipment could result in
equipment damage and may cause a safety hazard.
11. Do not deploy Cambium Networks power injectors in an outdoor environment.
12. Structures, equipment, and people must be protected against electrostatic discharge:
l
By siting equipment in a lightning protection zone.
l
By installation of appropriate lightning conductors to conduct the surge current to ground
via a separate preferential solid path.
l
Ground bonding and transient voltage surge suppression is recommended. Use Cambium
specified surge suppressors.
13. Use outdoor rated cables for connections that will be exposed to the outdoor environment. Install
Cambium recommended cables.
14. The Sierra and Palisade may be hot to the touch when in operation. The cnRanger 800 BBU must
not be operated in ambient temperatures exceeding 40°C unless mounted in a Restricted Access
Location. Select a location where the cnRanger 800 BBU can operate within safe ambient
temperature limits.
15. If a restricted access location is not available, confirm that the ambient temperature never exceeds
40°C. At this ambient temperature, the temperature of the external metal cases of the Sierra will
not exceed the touch temperature limit of 70°C. If a restricted access location (as defined in EN
90650-1) is available, confirm that the ambient temperature never exceeds 55°C. At this ambient
temperature, the temperature of the external metal case of the Sierra may exceed the touch
temperature limit of 70°C, but will be less than the maximum operating temperature of 95°C.
