Important safety information
II
phn-2513_004v000 (Oct 2012)
Electrical safety
The power cable connections must meet International Electrotechnical Commission (IEC)
safety standards.
Always power down and unplug the equipment before servicing.
When using alternative DC supplies, such as battery-backed DC power source, the supply
must be SELV rated.
Primary disconnect device
The power supply must include a primary disconnect device with appropriate fusing.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that will
be exposed to the weather.
RF exposure near the antenna
Strong radio frequency (RF) fields will be present close to the antenna when the
transmitter is on. Always mute the transmitter before undertaking maintenance activities
in front of the antenna.
Ensure that people cannot stand or walk in front of the antenna within ± 10 degrees of the
antenna axis and within the minimum distances listed in Table 210 (ETSI) or Table 211
(FCC). The minimum distances in these tables have been calculated using worst-case
assumptions. Reduced separation distances may be appropriate under some
circumstances. Further details are provided in Radiation hazard assessment on page 4-86.
Thermal safety
The CMU may be hot to the touch when in operation. The CMU must not be operated in
ambient temperatures exceeding 40 deg C unless mounted in a Restricted Access
Location. For more information, see Maximum operating ambient temperature for the
CMU on page 5-77.
