Fig. 1-1, Main Features of the XM3.1-HP Series Power Supply
1.0 Overview
The XM3.1-HP provides Outputs 1 & 2 for powering broadband devices and one auxiliary output for powering ancillary
devices in the enclosure. The output voltage for Output 1 and 2 are dependent on the model of the power supply and
the location of the Vout Selection Tap. The output voltage of Auxiliary Output 1 is dependent on the model. See page
5 for model numbers and their corresponding output voltages. The XM3.1-HP is composed of the following embedded
modules:
Transformer Module —
provides a critical load with current-limited regulated AC power that is free of spikes, surges,
sags and noise.
Power Processing Module (PPM) —
contains circuits for the Inverter, Sensing, Relays and Input/Output power.
Power Control Module (PCM) —
controls the core power supply functions such as Line Mode (AC Input), Inverter,
Battery Charger, Data Storage and AC Output.
Element Monitoring Module (EMM) —
is the interface between the Power Control Module and the Cable Modem Module
(CMM). The EMM provides the necessary data storage and performs advanced functions such as logging power supply
events, utility events, and battery health analysis. Additionally, the EMM provides the interface for the local web page and
logic for the ancillary equipment such as tamper switches.
NOTE: Should the EMM be removed, the Smart Display will
be disabled.
Cable Modem Module (CMM) —
interfaces with the EMM to provide the necessary communication over the DOCSIS
®
and Ethernet networks. The CMM enables the local Ethernet port for local web server access. The CMM may be removed
from the power supply along with the EMM.
NOTE: Smart Display functionality will cease until the EMM is installed.

Introduction
This guide describes the XM3.1-HP power supply (3 and 5 Amp models) and provides procedures with regard to the
installation of the power supply, battery connection, the Smart Display, initial startup and test, battery configuration and
verification of successful installation. For detailed information, refer to the XM3.1-HP Broadband UPS™ Technical Manual
for 3 & 5 Amp Models
(Alpha p/n 017-947-B0-001)
available at www.alpha.com.
This guide is intended for experienced, qualified and licensed installation personnel familiar with the mechanical and
electrical requirements of power supply enclosure systems. Review the XM3.1-HP Broadband UPS™ 3 & 5 Amp
Technical Manual
and other support documentation on the website to become familiar with the features and functions of
the equipment in this system before proceeding. Failure to install and/or use this equipment as instructed in the system
documents can result in a hazard to personnel or damage to the equipment. Once installation is complete, only qualified
personnel should service the system.
