Product Safety Information
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 60 GHz cnWave™ radio nodes. Ensure that
only qualified personnel install 60 GHz cnWave radios.
1. Exercise extreme care when working near power lines and at heights.
2. Always use one of the approved power supply options. Failure to use the Cambium supplied PSUs
could result in equipment damage and will invalidate the safety certification and may cause a safety
hazard.
3. The cnWave radios 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.
4. Always use an appropriately rated and approved AC supply cord-set in accordance with the
regulations of the country of use.
5. Before servicing 60 GHz cnWave™ equipment, always switch off the power supply and unplug it
from the PSU. Do not disconnect the RJ45 drop cable connectors from the radio while the PSU is
connected to the power supply. Always remove the AC or DC input power from the PSU.
6. The main power supply is the primary disconnect device.
7. Safety may be compromised if outdoor rated cables are not used for connections that will be
exposed to the outdoor environment.
8. The PSU output voltage may be hazardous in some conditions, for example in wet weather. Do not
connect a drop cable tester to the PSU, either directly or via LPUs.
9. Strong Radio Frequency (RF) fields will be present close to the antenna when the transmitter is on.
Always turn off the power to the radio before undertaking maintenance activities in front of the
antenna.
10. Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to radiate RF
energy as soon as they are powered up. Never work in front of the antenna when the radio is
powered. Install the radios so as to provide and maintain the minimum separation distances from all
persons. For minimum separation distances, see Separation distances table in
60 GHz cnWave™
User Guide.
11. Ensure that the installation meets the requirements defined in Installation section in
60 GHz
cnWave™ User Guide.
