Table 4.2 Attaching Ground and Power Cables Procedure Summary
WARNING: Ensure that all of the circuit breakers on each power
distribution panel (PDP) are in the OFF (down) position before attaching any
cables. Failure to do so may result in personal injury and cause damage to or
destruction of the basestation.
Access to the ground and power terminals is prevented by the rear cover of the
PDP. The rear cover should always be attached to the PDP during basestation
operation. This prevents foreign objects from accidently coming into contact
with the live wires and causing a short.
