INSTALLATION

2-1. INTRODUCTION

This section contains unpacking, inspection, and installation instructions and recommendations for

the Model NTGY71AA Multichannel 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

-4. INSTALLATION INSTRUCTIONS (Refer to figure 1-1) The NTGY71AA 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.
