Safety Precautions & Declared Material
Public and Occupational Boundary Distances Under Article 3.1(a)
of the RE Directive
Based on the highest nominal output power of the PTP 820C HP:
•
The public exposure of compliance boundary distance is 24.6m.
•
The occupational exposure of compliance boundary distance is 4.9m. This is the worst case for
the highest nominal output power, using antennas up to 3 ft. For all other configurations, the
compliance boundary distance is 0.
Note
Note that even when the compliance boundary is a non-zero value, this only applies within
the bore sight of the antenna dish. Therefore, during work within and close to the front of
the antenna, make sure the transmitters are turned off. As long as the transmitters are turned
off during any work on the system, the occupational exposure limit is not of concern to
workers operating in or around the parabolic dish antenna.

hazard:
Disconnecting one power supply disconnects only one power supply module. To isolate the
