2-4. INSTALLATION INSTRUCTIONS
The G3L-800-25-001 amplifier module is designed for installation in a subrack that permits access
to the subrack for connection of DC power, RF, and monitor cables.
To install the amplifier proceed as follows:
1. Install subrack in equipment rack or cabinet and secure in place.
2. Connect antenna cable to subrack.
3. Connect the transceiver output(s) to subrack.
4. Connect RS-232 cable to subrack.
5. Connect alarm and control cables to subrack.
WARNING
Verify that all circuit breaker switches on the subrack
are in the OFF position. Turn off external primary DC
power before connecting DC power cables.
7. Connect positive primary power and negative primary power to the subrack. Tighten the
subrack power connections.
8. Place power on/off switch on the amplifier front panel in the “off” (down) position. Insert the
plug-in amplifier module(s) in the subrack. Tighten top and bottom thumbscrews.
9. Check your work before applying DC voltage to the system. Make certain all connections are
tight and correct.
10. Measure primary DC input voltage. DC input voltage should be +27 Vdc ±1.0 Vdc. If the DC
input voltage is above or below the limits, call and consult Powerwave before you turn on your
amplifier system.
11. Refer to section 3 for initial turn-on and checkout procedures.
