SECTION TWO : INSTALLATION 

 

! CAUTION ! 

 
These  Amplifiers  operate  at 

high  RF  power  levels,  internal  supply  energy  levels  and  mains 

supply  current  levels

.  They  also  incorporate  devices  containing 

toxic  BeO

.  Before  commencing 

installation, it is recommended that the complete INSTALLATION section is read and understood. 

The 

instructions  should  then  be  strictly  followed,  by  suitably  qualified  personnel,  otherwise  sub-
standard or even dangerous operation may result. 
 

2.1 : PHYSICAL DIMENSIONS AND FITTING 
 
2.1.1 Installation Accessories 
 
Various installation accessories may be supplied as required. A list of these (including spare fuses) is 
given below. Actual requirements depend on the configuration of the equipment supplied (e.g. with or 
without  Exciter/Drive(s),  separate  to  or  already  fitted  into  a  19  inch  rack,  whether  or  not  leads  are 
supplied  ready  made  etc.).  Note  that  extra,  unlisted  parts  may  be  required  for  connections  to  any 
Exciter/Drive(s) that are supplied (see manuals supplied with them).
