 SPA9329-35N Installation & Service Manual Section 2  Installation 2-1  Introduction This section contains unpacking, inspection, and installation instructions and recommendations for the Powerwave model SPA9329-35N Two-Channel Power Booster Amplifier module. Care-fully 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. If applicable, carefully read the appropriate parts of the Federal Communications Commission (FCC) rules to determine how they apply to your instal-lation. 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. 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 vulner-ability 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 & Inspection This equipment has been operated, tested, and calibrated at the factory. Carefully open the con-tainer(s) and remove the amplifier module(s). Retain all packing material that can be reassem-bled 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 pack-ing 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 pres-ence of the delivery person. If the equipment is damaged, the carrier is your first area of re-course. If the equipment is damaged and must be returned to the factory, write or phone for a re-turn authorization (see paragraph 6.3). Powerwave may not accept returns without a return au-thorization. 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.
