2 SAFETY
CONSIDERATIONS
2.1 Electrical Shock
Electrical shocks cause by incompatible power supplies.
This hazard can be avoid or minimized by quality installation practice and thorough testing during:
a) Original assembly;
b) Commissioning, and
c) Regular intervals, thereafter.
All test equipment must be in good working order prior to its use. High current power supplies can
be dangerous because of the possibility of substantial arcing. To be safe, always switch the
equipment to off during connection and disconnection.
2.2 RF Radiation Hazard
RF radiation, (especially at microwave frequencies) arising from transmitter outputs connected to
Celltronik’s equipment, must be considered a safety hazard.
This condition might only occur if the cable is disconnected, or the output of the amplifier is not
properly terminated. Either of these conditions would impair the system’s efficiency. No
investigation should be carried out until all RF power sources have been removed. This would
always be a wise precaution, despite the severe mismatch between the impedance of an N type
connector at 50Ω, and that of free space at 377Ω, which would severely mitigate against the
efficient radiation of RF power. Radio frequency burns could also be a hazard, if any RF power
carrying components were to be carelessly touched.
Antenna positions should be chosen to comply with requirements (both local & statutory)
regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is capable
of producing RF field strengths, which may exceed guideline safe values especially if used with
