Always ensure that the circuit breaker in the building/site electrical 
service panel or AC disconnect device is in the OFF position prior to 
beginning any installation work in repeater cabinet.  This will prevent 
injury caused by electric shock and prevent damage to equipment. 
 
During the installation procedure, several components must be installed in the HPA 
compartment: 
 
  Low Band and High Band HPA’s 
  HPA 30 VDC Rectifiers 
 
NOTE: The components/sub-assemblies installed in the HB cabinet HPA compartment and LB
