Introduction
Only qualified personnel should install the AlphaDOC. To install the AlphaDOC you must completely shut
down the Power Supply. To maintain output to the load, consider using either the APP9015S or APP9022S
Service Power Supply during installation.
To avoid exposing the technician to potentially lethal voltages, before you proceed you
must remove all power from the Power Supply; unplug the Power Supply from the AC
power source, remove all front panel connections and disconnect the battery connector.
