WARNING!
Installing the XP-EDH-A2 transponder at an Alpha AM power supply site requires shutting
down the power supply. If a short power interruption is not feasible, you must use an
alternate source of system power during the installation of the transponder. This is
necessary to install the RPM interface card, and to make connections to the output of the
power supply to permit monitoring of the output voltage of the power supply.
If a short power interruption is not feasible, you must use an alternate source of system
power during the installation of the transponder.
