Safety Notes
This symbol identifies conditions and actions that pose a hazard to the user.
This symbol cautions the user of conditions and actions that may damage the
powersupply or associated equipment.
This symbol identifies a condition that may be corrosive to equipment and parts,
or damaging to skin.
This symbol identifies a condition in which it is required to recycle discarded
materials.
This symbol identifies a situation in which static-sensitive components are present.
Warnings
WARNING: This power supply and its associated hardware (enclosure, batteries,
cabling) may contain equipment, batteries or parts which have accessible
hazardous voltage or currents.
T o av oid injury
:
• This power supply and its associated hardware must be serviced by authorized
personnel only .
• The enclosure which contains the power supply and associated equipment must remain
locked at all times, except when authorized service personnel are present.
• Remove watch and/or jewelry prior to servicing equipment, parts, connectors, wiring, or
batteries.
• Read and follow all installation, equipment grounding, usage, and service instructions
included in this manual.
• Use proper lifting techniques whenever handling equipment, parts, or batteries.
• Batteries contain dangerous voltages, currents and corrosive material. Battery
installation, maintenance, service and replacement must be performed by authorized
personnel only .
• Never use uninsulated tools or other conductive materials when installing, maintaining,
servicing or replacing batteries.
• Use special caution when connecting or adjusting battery cabling. An improperly
connected battery cable or an unconnected battery cable can result in arcing, a fire, or
possible explosion.
• A battery that shows signs of cracking, leaking or swelling must be replaced immediately
by authorized personnel using a battery of identical type and rating.

Safety
Warnings,
continued
• Avoid any contact with gelled or liquid emissions from a valve-regulated lead-acid
(VRLA) battery . Emissions contain dilute sulfuric acid which is harmful to the skin and
eyes. Emissions are electrolytic, which are electrically conductive and are corrosive.
Follow the Chemical Hazards notes if contact occurs.
• Do not smoke or introduce sparks in the vicinity of a battery .
• Under certain overcharging conditions, lead-acid batteries can vent a mixture of
hydrogen gas which is explosive. Proper venting of the enclosure is required.
• Follow the battery manufacturer’s approved transportation and storage instructions.
Cautions
NOTE: Equipment or parts may be damaged or cause damage if used or
installed improperly .
T o a void 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. V erify load requirements prior and during
connection process.
• Prior to handling the batteries, touch a grounded metal object to dissipate any static
charge that may hav e dev eloped in your body.
The circuit board contains static-sensitive components. Please follow all appropriate
ESD (Electro Static Discharge) handling practices. As an extr a precaution, handle the
USM2.5 with Acterna Embedded Transponder Module b y the edges and keep fingers awa y
from card edge connectors.

Battery Safety
Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery
installation, maintenance, service and replacement must be performed by authorized personnel
only.
Any gelled or liquid emissions from a V alve-Regulated lead-acid (VRLA) battery
contain dilute sulfuric acid, which is harmful to the skin and eyes. Emissions are
electrolytic, which are electrically conductive and corrosive.
Chemical Hazards
T o avoid injury:
Safety
• Wear protective clothing (insulated gloves, eye protection, etc) whenever installing,
maintaining, servicing, or replacing batteries.
• If any battery emission contacts the skin, wash immediately and thoroughly with water .
Follow your company’s approved chemical exposure procedures.
• If any battery emission contacts the eye, wash immediately and thoroughly with water for
10 minutes with pure water or a special neutralizing eye wash solution and seek
immediate medical attention. Follow your company’s approved chemical exposure
procedures.
• Neutralize any spilled battery emission with the special solution contained in an approved
spill kit or with a solution of 1 lb. bicarbonate of soda to 1 gal of water. Report chemical
spill using your company’s spill reporting structure and seek medical attention if
necessary.
• Always replace batteries with those of an identical type and rating. Never install old or
untested batteries.
• Do not charge batteries in a sealed container . Each individual battery should have at least
0.5 inches of space between it and all surrounding surfaces to allow for convection cooling.
• All battery compartments must have adequate ventilation to prevent an accumulation of
potentially dangerous gas.

Safety
Maintenance Guidelines
The battery maintenance instructions listed below are for reference only . Battery manufacturer’s
instructions for transportation, installation, storage or maintenance take precedence over these
instructions.
• T o prevent damage inspect batteries every 3 months for:
-Signs of battery cracking, leaking or swelling. The battery should be replaced
immediately by authorized personnel using a battery of the identical type and rating.
-Signs of battery cable damage. Battery cable should be replaced immediately by
Authorized Personnel using replacement parts specified by vendor .
-Loose battery connection hardware. Refer to battery manufacturer’s documentation
for the correct torque and connection hardware for the application.
• Apply battery manufacturer’s specified antioxidant compound on all exposed connections.
• Verify battery terminals and/or exposed connection hardware has not shif ted within 2
inches of a conductive surface. Reposition batteries as necessary to maintain adequate
clearance.
• Clean up any electrolyte (battery emission) in accordance with all federal, state, and local
regulations or codes.
Recycling and Disposal Instructions
Spent or damaged batteries are considered environment ally unsafe. Always recycle used
batteries or dispose of the batteries in accordance with all federal, state and local
regulations.

1.1 Installation in an XM Series 2 Power Supply
1. Record the transponder address (located on the sheet
metal of the front panel).
2. Open the power supply enclosure.
NOTE: Backup power will not be available while
batteries are disconnected.
3. Set the battery breaker on the front of the power
supply to the OFF position.
4. Unplug all connectors on the front of the power
supply inverter module.
5. Loosen the thumb screws holding the inverter
module into the power supply.
6. Slide the inverter module out far enough to unplug
the ribbon cable at the back of the inverter module
(fig A). Disengage the tw o latches holding the plug
into the socket (fig. B), and remove the plug.
