2-4.  INSTALLATION INSTRUCTIONS  (Refer to figure 1-1)
The NTGY81AC amplifier module is designed for installation on a heatsink that permits access to
the 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 amplifier

module 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.

 

 
4.  Connect power, alarm, and control cables to matching P1 through P5 connectors.  Refer to

paragraphs 2-5 through 2-9 following.

6.  Check your work before applying DC voltage to the system.  Make certain all connections are

tight and correct.

 
7.  Measure primary DC input voltage.  DC input voltage should be +26 ±0.5 Vdc.  If the DC input

voltage is above or below the limits, call and consult Powerwave before you turn on your
amplifier system.

 
8.  Refer to section 3 for initial turn-on and checkout procedures.

2-5. +26 VDC POWER AND GROUND CONNECTOR P1
The +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.
