NTUM30DA Installation & Service Manual
Section 2 Installation
2-1 Introduction
This section contains unpacking, inspection, and installation instructions and recommendations
for the Model NTUM30DA Multi Channel Power Amplifier. Carefully read all material in this sec-
tion 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 Com-
munications 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 -48 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 elec-
trical 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 extrane-
ous 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 impor-
tance 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 re-
course. 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 CAR-
