Overview to the eld installation instructions
CAUTION!
Use a surge protector in the cabinet when the transformer is used to measure line voltage.
Do not place the transponder on top of the power supply or batteries.
Make all battery harness connections and connect the interface cable to the power supply before
connecting the cables to the transponder.

The XP-EDH3 transponder provides the ability to manage network power through an existing cable modem
infrastructure, for a variety of power supplies as shown in this document.
These instructions provide information important to the successful installation, connection and operational verication of
the Alpha XP-EDH3 transponder in a variety of systems.
Save these instructons for future reference.
Alpha AM power supplies with RPM interface cards marked 700-019-28, 700-019-31 and 700-019-40 are
compatible with the DOCSIS HMS Analog Transponder.
NOTE:
NOTE:

1. Switch Battery Breaker OFF prior to removing the Inverter Module for USM Card installation and conguration.
A chipset upgrade may be required; contact Alpha for more information.
Set the jumpers and calibrate the USM card before making connections and applying the load.
When connecting to an AM Series power supply, plug the 13-pin
connector so the black wire is in pin1 and two open pins are left
at the left for tamper switch connection (as viewed from the front
of the unit)..

WARNING!
When installing Battery Sense Cable Kit (BSC) or AlphaGuard sense cable, do not connect the black
(negative) wire of the BSC to the negative post on Battery 1.
2. It is advisable to install the Battery or Aux pwr cables (providing power to the External DOCSIS unit) and waiting until
the RDY LED is ashing normally before installing the power supply interface kit. This will reduce the chances of the
power supply transferring to inverter due to a low signal reference on the test control pin.
When connecting to an XM Series power supply, plug the 13-pin
connector so the black wire is in pin1 and two open pins are left at
the bottom for tamper switch connection (as viewed from the front
of the unit).

The XM2 batteries are isolated from chassis ground by design. Any voltage potential difference between battery (-)
and chassis ground must be eliminated before installing the transponder to avoid potential transponder damage. To
accomplish this, attach a ground jumper between battery (-) and chassis ground before installing the transponder. Once
the transponder is installed the jumper may be removed if desired.
WARNING!
Connection Instructions for the Alpha XM Series 2 Power Supply
Switch Battery Breaker OFF prior to removing the Inverter Module for USM2/USM2.5 Card installation and conguration.
When connecting to an XM Series 2 power supply, plug the 13-pin
connector so the black wire is in pin1 and two open pins are left at
the top for tamper switch connection.
