2.4.1 Power Amplifier Modules
The PA1000 incorporates four power amplifiers (two each in two modules). Due to
possible damage during shipment, the power modules have been removed. Follow
these steps to install the modules:
1. Remove the front panel of the PA1000 (four screws).
2. Taking ESD precautions (see page 2–2), unpack the power modules and place
them on your work area with the circuit sides up.
3. The warning labels on the front of the modules should all be positioned to the
center of the chassis, also note the position of the connector on the modules
and in the chassis.
4. Insert the two power modules, using their slide rails, into the built in chan-
nels of the right-side cavity as shown below. Note that the connectors and
warning labels are nearest the middle wall or partition of the PA1000.

5. Be sure the modules are pushed in completely so that the connector makes
proper contact.
6. Replace the front panel of the PA1000.
