ERIES
2.4 Preparing for Installation
It is recommended that an electrical inspection for verification of customer interface connections
be performed before and after the installation of the equipment in its final operational location;
the following basic steps must be completed:
1. Verify proper CHPA RF input and output terminations. (See Warning.)
2. Verify that all CHPA user interface connectors to be used match pin-out data in Chapter 3,
"Interfaces."
3. Verify proper prime power connection to the CHPA.
Chapter 7, for AC voltage specifications.
Warning: Operating the Compact High Power Amplifier (CHPA) without
proper termination or under excessive load voltage standing wave ratio
(VSWR) could cause destruction of the traveling wave tube (TWT) and will
void the warranty. (See specifications in See Drawings & Schematics in
Chapter 7.)
2.5 Installation
Installation of the CHPA includes four phases:
•
Mechanical installation
•
Electrical connections
•
RF connections
•
Cooling considerations
2.5.1
Mechanical Installation
The CHPA is designed for rack slide mounting in a standard 19-inch (48.3 cm) wide rack
cabinet. Use the following procedure for this installation:
1. Determine the required front panel arrangement and exact panel locations for the CHPA on
the rack cabinet.
2. Mount the mating slides (supplied) to the rack cabinet using the supplied hardware.
3. Install the CHPA on the mating slides and securely fasten the front panel to the rack cabinet
rails.
Once the unit is installed on the slides and fastened to the cabinet, the balance of the installation
procedures can be completed.
