INSTALLATION
2-1. INTRODUCTION
This section contains installation recommendations, unpacking, inspection, and installation
instructions for the multicarrier PCS amplifier. Carefully read all material in this section prior to
equipment unpacking or installation. Also read and review the operating procedures in Section 3
prior to installing the equipment. It is important that the licensee perform these tasks correctly and
in good faith. If applicable, carefully read Parts 73 and 74 of the Federal Communications
Commission (FCC) rules to determine how they apply to your installation. DON'T TAKE
CHANCES WITH YOUR LICENSE.
2-2. ELECTRICAL SERVICE RECOMMENDATIONS
Powerwave Technologies recommends that proper AC line conditioning and surge suppression be
provided on the primary AC input to the +27 Vdc power source. All electrical service should be
installed in accordance with the National Electrical Code, any applicable state or local codes, and
good engineering practice. Special consideration should be given to lightning protection of all
systems in view of the vulnerability of most transmitter sites to lightning. Lightning arrestors are
recommended in the service entrance. Straight, short ground runs are recommended. The
electrical service must be well grounded.
Each amplifier system should have its own circuit breaker, so a failure in one does not shut off the
whole installation. Circuit breakers should be thermal type, capable of handling the anticipated
inrush current, in a load center with a master switch.
2-3. UNPACKING AND INSPECTION
This equipment has been operated, tested and calibrated at the factory. Only in the event of
severe shocks or other mistreatment should any substantial readjustment be required. Carefully
open the container(s) and remove the amplifier module(s). Retain all packing material that can be
reassembled in the event that the unit must be returned to the factory.
CAUTION
Exercise care in handling equipment
during inspection to prevent damage
caused by rough or careless handling.
Visually inspect the amplifier module for damage that may have occurred during shipment. Check
for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous
packing material in the connector or fans. Inspect the rear panel connector for bent connector
pins. If the equipment is damaged, a claim should be filed with the carrier once the extent of any
damage is assessed. We cannot stress too strongly the importance of IMMEDIATE careful
inspection of the equipment and the subsequent IMMEDIATE filing of the necessary claims against
the carrier if necessary. If possible, inspect the equipment in the presence of the delivery person.
If the equipment is damaged, the carrier is your first area of recourse. If the equipment is
damaged and must be returned to the factory, write or phone for a return authorization.
Powerwave may not accept returns without a return authorization. Claims for loss or damage may
not be withheld from any payment to Powerwave, nor may any payment due be withheld pending
the outcome thereof. WE CANNOT GUARANTEE THE FREIGHT CARRIER'S PERFORMANCE.

2-4. INSTALLATION INSTRUCTIONS (Refer to figures 1-1 and 2-1)
The G3S-1900-80 amplifier module is designed for installation in a subrack that permits access to
the rear of the subrack for connection of DC power, RF, and monitor cables.
To install the amplifier proceed as follows:
1. Install subrack in equipment rack and secure in place.
2. Connect antenna cable to rear of subrack.
3. Connect the transceiver output(s) to rear of subrack.
4. Connect alarms cable(s).
WARNING
Verify that all circuit breaker switches on the rear
panel of 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.
subrack power connections.
Tighten the
8. Install the plug-in amplifier module(s) in the subrack. Verify that the latch is properly seated.
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.
2-5 AMPLIFIER MODULE CONNECTORS
The amplifier has three connectors on the right rear of the module. The largest is a 21-pin male
D-Sub combo which provides the status, alarm, control, and power connections. The smaller
connectors are BMA female coaxial contacts from Radiall, which provide the RF connections.
Refer to figure 2-1.

2-5.1. AMPLIFIER MODULE STATUS, ALARM, CONTROL, AND POWER CONNECTOR
The amplifier has a separate remote alarm and control connector which may be used by the host
system to monitor and control the individual amplifier modules. The status, alarm, control, and
power connections on the amplifier connector are made through a 21-pin male D-Sub combo
connector (figure 2-2) and are listed and described in table 2-1.
