044-05080 Rev. A 2-1INSTALLATION2-1. INTRODUCTIONThis section contains unpacking, inspection, and installation instructions and recommendations forthe Model NTGY71AA Multichannel Power Amplifier. Carefully read all material in this section priorto equipment unpacking or installation. Also read and review the operating procedures in Section 3prior to installing the equipment. It is important that the licensee perform these tasks correctly andin good faith. If applicable, carefully read the appropriate parts of the Federal CommunicationsCommission (FCC) rules to determine how they apply to your installation. DON'T TAKE CHANCESWITH YOUR LICENSE.2-2. ELECTRICAL SERVICE RECOMMENDATIONSPowerwave Technologies recommends that proper AC line conditioning and surge suppression beprovided on the primary AC input to the +26 Vdc power source. All electrical service should beinstalled in accordance with the National Electrical Code, any applicable state or local codes, andgood engineering practice. Special consideration should be given to lightning protection of allsystems in view of the vulnerability of most transmitter sites to lightning. Lightning arrestors arerecommended in the service entrance. Straight, short ground runs are recommended. Theelectrical service must be well grounded.Each amplifier system should have its own circuit breaker, so a failure in one does not shut off thewhole installation. Circuit breakers should be thermal type, capable of handling the maximumanticipated inrush current, in a load center with a master switch.2-3. UNPACKING AND INSPECTIONThis equipment has been operated, tested and calibrated at the factory. Carefully open thecontainer(s) and remove the amplifier module(s). Retain all packing material that can bereassembled in the event that the unit must be returned to the factory.CAUTIONExercise care in handling equipmentduring inspection to prevent damagecaused by rough or careless handling.Visually inspect the amplifier module for damage that may have occurred during shipment. Checkfor evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous packingmaterial in the connector. If the equipment is damaged, a claim should be filed with the carrier oncethe extent of any damage is assessed. We cannot stress too strongly the importance ofIMMEDIATE careful inspection of the equipment and the subsequent IMMEDIATE filing of thenecessary claims against the carrier if necessary. If possible, inspect the equipment in thepresence of the delivery person. If the equipment is damaged, the carrier is your first area ofrecourse. If the equipment is damaged and must be returned to the factory, write or phone for areturn authorization. Powerwave may not accept returns without a return authorization. Claims forloss or damage may not be withheld from any payment to Powerwave, nor may any payment duebe withheld pending the outcome thereof.

INSTALLATION INSTRUCTIONS (Refer to figure 1-1)The NTGY71AA amplifier module is designed for installation on a heatsink that permits access tothe 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 amplifiermodule 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.WARNINGTurn off external primary DC powerbefore connecting any cables.4. Connect power, alarm, and control cables to matching P1 through P5 connectors. Refer toparagraphs 2-5 through 2-9 following.6. Check your work before applying DC voltage to the system. Make certain all connections aretight and correct.7. Measure primary DC input voltage. DC input voltage should be +26 ±0.5 Vdc. If the DC inputvoltage is above or below the limits, call and consult Powerwave before you turn on youramplifier system.8. Refer to section 3 for initial turn-on and checkout procedures.2-5. +26 VDC POWER AND GROUND CONNECTOR P1The +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 2-1.321Figure 2-1. +26 Vdc Power and Ground Connector P1Table 2-1. +26 Vdc Power and Ground Connector P1 DefinitionPIN SIGNAL DESCRIPTION1+26V +26 Vdc for MCPA2+26V_RTN +26 Vdc return, grounded to MCPAchassis ground.3Chassis Gnd.
