CAUTION
Before applying power, make sure that all connectors are secure. Make sure
that the input and output are properly terminated at 50 ohms. Do not operate
the system without a load attached. Refer to Table 1-2 for input power
requirements. Excessive input power may damage the equipment.
If the equipment is damaged:
• The carrier is your first area of recourse.
• 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 the equipment is damaged and must be returned to the factory:
• Please write or phone for return authorization.
• Powerwave may not accept returns without a return authorization.
2-6 Installation Instructions
Install the G3L-850-135 amplifier as follows:
WARNING
Turn off external primary DC power before connecting DC power
cables.
2-6.1 Installing the Amplifier into the Subrack
1. For each Amplifier:
a. Inspect the 21WA4 male combo connector on the rear of each amplifier. Verify that all
pins are straight, no pins are recessed, packing material is removed, and that the
alignment shield is not bent.
b. Set the amplifier power Reset/On/Off switch to “Off” (down position) as shown in Figure
2-1.
CAUTION
Do not slam or force the amplifier into the subrack. This may cause the pins
on the 21-D sub connector of the amplifier to become recessed or broken.
Note
Non-combining subracks are typically sector specific; ensure the amplifier is installed
to support the appropriate sector.
c. With the thumbscrews in the unlock position, install the amplifier(s) into the subrack.
There are no slot priorities in a combining subrack, so all slots function equally. To
secure the amplifier(s) in the subrack, turn the top and bottom thumbscrews to the lock
position as shown in Figure 2-1.
WARNING
Check your work before applying DC voltage to the amplifier. Make certain all
connections are tight and correct.
