Section 6: Installing the RF connector
The XR12 comes with one of several types of RF output connectors. All types are illustrated in this
section.
Preparation
1. Make sure that the ac power is turned off at the ac service entrance.
2. Gain access to the
Exciter Panel
assembly by opening the door containing the GUI and
control panel on the front of the transmitter. The door is not latched and just swings open to
the left.
3. Remove all 14
Exciter Panel
assembly mounting screws ( Figure 6.1 on page 6-2 ), then swing
the
Exciter Panel
to the left to open it and expose the inside of the filter.
4. On the back wall of the filter, there is an
Output Strap
attached to two disc-shaped
capacitors (e.g., see Figure 6.2 on page 6-3 and the Note below). Perform the steps in the
following sections to install the appropriate RF output connector.
5. If you are proceeding to “Adjusting the spark gap” on page 7-1 after installing the RF
connector, leave the
Exciter Panel
open until the completion of that procedure.
