WARNING!
Installing the XP-EDH-A transponder requires temporarily disconnecting the output of the
power supply to the cable plant to insert one of the transponder harnesses in series with
the power supply output. This is necessary so the transponder can measure both the output
voltage and output current.
If a short power interruption is not feasible, you must use an alternate source of system
power during the installation of the transponder.
3.3.1 Connecting the XP-EDH-A to an AM/AP Series
Follow Fig. 3-9 to make connections between the transponder and the power supply
site.
Figure 3-9 is the cable installation guide for the power supply interface, three
batteries, and the Alpha AM/AP power supply.
