2 November-2007 Bulletin II-102051-EN • Revision B
All operations relating to the installation of the PDU must be executed in accordance with industry
approved safety standards and practices. The installer shall also follow the safety practices
recommended by the BTS provider to insure that the BTS operation is not compromised.
#$ %&
The BTS, antenna line equipment, and the
antennas generate high frequency electric and
magnetic fields when in operation. The high
density energy can damage the eyes and
certain tissues of the human body in persons
exposed to radiation near the antenna.
Shut down transmitters when work is
performed on the transmitter antenna and
antenna line equipment. Avoid remaining in the immediate vicinity of the antenna when the
transmitter is in operation.
%'(%&
The BTS equipment contains circuits that
generate high available short circuit currents.
Unintentional short circuits can cause
dangerous heating, fire, or equipment
damage.
Turn off circuit breakers or remove fuses
when work is performed on the power supply
circuits. Install or replace fuses with
appropriate voltage and amperage rating. Do not bypass or defeat overcurrent protection devices.
Do not remove equipment covers.
)!'*)!+
ESD can damage the BTS equipment or the
PDU during installation if proper precautions
are not taken. The damage may cause an
immediate failure of the device, or remain
latent and lead to a failure some time in the
future.
Discharge static build-up by touching the metal
enclosure before making connections. Do not
remove equipment covers.
RADIO FREQUENCY
ENERGY CAN CAUSE
INJURY OR BURNS.
Turn off transmitters before
servicing antenna line equipment.
HIGH CURRENT HAZARD.
Short circuit currents can cause
burns or fire.
Use only fuse of appropriate
voltage and amperage rating.
ELECTROSTATIC SENSITIVE
DEVICES.
Use proper grounding techniques
to prevent equipment damage.
