INSTALLATION
2-1. INTRODUCTION
This section contains unpacking, inspection, and installation instructions and recommendations for
the Model NTGY81AA Single Channel Power 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 the appropriate parts 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 +26 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 maximum
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. 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. 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 figure 1-1)
The NTGY81AA amplifier module is designed for installation on a heatsink that permits access to
the module for connection of RF cables and the power, alarm, and control connector.
To install the amplifier proceed as follows:
1. Install amplifier on heatsink with thermally conductive material inserted between amplifier
module and heatsink, and secure in place with appropriate mounting screws.
2. Connect the antenna cable to RF OUT female SMA connector.
3. Connect the transceiver output cable to RF IN frmale SMA connector.
WARNING
Turn off external primary DC power
before connecting any cables.
4. Connect power, alarm, and control cables to matching P1 through P5 connectors. Refer to
paragraphs 2-5 through 2-9 following.
6. Check your work before applying DC voltage to the system. Make certain all connections are
tight and correct.
7. Measure primary DC input voltage. DC input voltage should be +26 ±0.5 Vdc. If the DC input
voltage is above or below the limits, call and consult Powerwave before you turn on your
amplifier system.
8. Refer to section 3 for initial turn-on and checkout procedures.
2-5. +26 VDC POWER AND GROUND CONNECTOR P1
The +26 Vdc power and ground connections on the amplifier are made through an 3-pin female D-
Sub connector (figure 2-1) and are listed and described in table 2-1.
