Safety
Cautions
NOTE: Equipment or parts may be damaged or cause damage if used or
installed improperly.
To avoid damage
:
• Prior to installation, verify that the AC input voltage to the enclosure and its equipment
match with respect to voltage and frequency.
• Prior to installation, verify that the output voltage from the enclosure or its equipment
match the voltage requirements of the connected equipment (load).
• Prior to installation, verify that the enclosure’s utility service panel is equipped with a
properly rated circuit breaker for use with the equipment inside. Refer to manufacturer’s
recommendations.
• Review and upgrade utility service panel circuit breaker requirements whenever the
equipment within the enclosure is changed.
• Prior to installation, contact local utilities, local building maintenance departments, and
cable/piping locator services to ensure that installation does not interfere with existing
utility or building cables/piping.
• Do not exceed the output rating of equipment. Verify load requirements prior and during
connection process.
• Prior to handling the batteries, touch a grounded metal object to dissipate any static
charge that may have developed in your body.

1.1 USM2.5 Introduction
This Operator’s and Technical Manual will cover the installation, signal definition, operation,
and basic troubleshooting for the USM2.5 when used with the Alpha XM Series 2 Power
Supply.
The USM2.5 card is a logic controller PCB which may be used to upgrade any XM Series 2
Power Supply for the purpose of remote status monitoring. As part of the Communications
Module upgrade, the USM2.5 connects directly to the XM2’s Inverter Module via an 18 pin
jumper. No recalibration of the power supply is required at the time of installation.
System Concept
The USM2.5 remote status monitoring system is comprised of the following basic building
blocks:
• An Alpha XM Series 2 Uninterruptible Power Supply.
• An approved transponder.
• The USM2.5 status monitoring card.
Operating through a transponder and status monitoring system, the operator may issue
commands to the USM2.5 to control the operating mode of the power supply; evaluate
potential fault conditions reported by the software; or run routine checks on the power supply.
1. Introduction
For example, the operator may issue a command that initiates a “Self-Test” mode to check
the inverter circuitry, status of the batteries, or obtain values for battery voltages. This kind
of information allows for a more accurate assessment of the operating condition, and ability
to supply uninterrupted performance of each power supply. More importantly, proper USM2.5
operations allow for preventive maintenance on an “as required” basis. This has obvious
advantages over a scheduled maintenance program, since service personnel can be
dispatched when required with the appropriate parts and tools.

2. Installation
2.1 Inverter Module Removal and Installation
The XM Series 2 Power Supply comes with a field-replaceable Inverter Module, containing
the inverter, battery charger and control logic circuitry. The Inverter Module is designed to
accept USM2.5 plug-in logic upgrades to facilitate remote status monitoring. The Inverter
Module can be removed while the power supply is running on line power. With the Inverter
Module removed, the power supply will continue to operate in a non-standby mode.
Remove the Inverter Module prior to adding the optional USM2.5 circuit board. Follow the
first procedure below precisely.
CAUTION: ALWAYS switch the battery breaker OFF prior to removing the Inverter Module.
XM Series 2 Inverter Module Removal Procedure:
1. Switch OFF the battery breaker. Disconnect the battery input, and the temp
probe cables.
2. Disconnect all remaining cables as needed from the Inverter Module.
3. Loosen the thumbscrews on the Inverter Module.
4. To remove the Inverter Module: grasp ONLY the handle of the Inverter Module,
pull firmly to release the module from the connector. Slide the module
assembly straight out.
5. Disconnect the Ribbon cable attaching the inverter module to the power
distribution board before sliding the inverter module all of the way out. (Refer
to Figure 2-1.)
XM Series 2 Inverter Module Installation Procedure:
1. Attach the ribbon cable to the inverter module.
2. To reseat the Inverter Module: align the metal shield in the upper and lower
card-guides. Using ONLY the Inverter Module’s handle (
pressure of any kind to the front panel
) firmly drive the module back into the
absolutely apply no
connectors. The connectors are designed to be made with reasonable force.
The thumbscrews are not intended to aid in making these connections, but
to secure the Inverter Module to the chassis.
3. If the Inverter Module is correctly seated the front panel Smart Display will
start-up, and the “Inverter Disconnected Alarm” will NOT be active.
4. Retighten thumbscrews. It is recommended that screws be tightened by
hand ONLY. Avoid using tools to tighten thumbscrews.
5. Reconnect all the cables (TMPR, XPDR, and SYS COM) as needed to the
Communications Module.
6. Verify that the battery breaker is OFF, reconnect the battery input and the
temp probe cables, verify battery polarity, and then finally switch ON the
battery breaker.

2.2 USM2.5 Installation
The optional USM2.5 status monitoring upgrade plugs into the XM Series 2 Inverter Module.
The USM2.5 can be configured for various status monitoring interfaces by setting the DIP
switch. Status monitoring interfaces are listed according to their manufacturer, along with
the associated parts in Section 3.1. The USM2.5 also accommodates a tamper switch
assembly to indicate unauthorized enclosure entries.
CAUTION: The USM2.5 PCB contains static sensitive components that could be easily
damaged if not handled properly.
When installing the USM2.5 use the following procedure:
USM2.5 Installation Procedure:
1. Refer to Section 2.1 for Inverter Module removal.
2. Install the USM2.5 assembly on the Inverter Module:
Tools Required: #2 Phillips head screwdriver.
2. Installation
a) The 2 x 9 pin Strip Connector (Fig. 2-3), must be installed onto the
Inverter Module. A properly installed strip connector will be fully
seated and firmly in place.
b) A new USM2.5 will come with a snap-on support. Position the
USM2.5 over the strip connector and the rear hole for the support
and carefully push into place. Verify the position of the strip connector,
and that the support is fully seated into the Inverter Module mounting
shield.
c) When replacing a USM2.5 the support may already be installed. If
so, align the USM2.5 over the supports and gently rock onto the
strip connector. verify the position of the strip connector, and that
the support is fully seated into the Inverter Module mounting shield.
d) Secure the top of the USM2.5 card to the Inverter Module with the
captive screw fastener. The lower portion is covered by an optional
blanking plate (Fig. 2-2) or an Internal Transponder. Use 2 #6 screws
to secure the blanking plate, or the two captive screw fasteners
with the Internal Transponder.
3. Setup the USM2.5 for proper operation (see Section 3, Configuration):
a) Before reinstalling the Inverter Module, set the DIP switch, SW1 to
the proper configuration settings for the status monitoring interface,
as per Table 3-1 (page 12). Always verify USM2.5 configuration
especially after upgrading or modifying the XM Series 2 Power
Supply.
4. Carefully reinstall the Inverter Module. Refer to section 2.1.
