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.

-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).

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. Figure 2-2.
