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.

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
