For all outputs in use, set the DC Output DIP switches to E NABLE (up) and the TMA Alarm DIP
switches to E NABLE (down). See Figure 17. For any unused outputs, set the corresponding DC
Output and TMA Alarm DIP switches to D ISABLE .

After completing the installation procedure, verify the installation by performing these tests. The
Functional Test can be done also prior to installing TMAs and/or Bias Tees.

The PDU will be fully functional only once all parts of the TMA system are installed and all
connections made (complete system). To check the PDU installation before TMAs and/or Bias Tees
are installed (incomplete system), ensure the Bias Tee Harness SMA connectors are left unattached
during the Functional Test.
