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.
