1 PRODUCT INTRODUCTION
1.1 GENERAL DESCRIPTION
The OPSU/BBU (ONT Power Supply Unit/Battery Back-Up Unit) is designed to be mounted
inside a customer premise. The OPSU/BBU converts 120Vac to 12Vdc and provides four to
eight hours of backup battery power for lifeline POTS and Ethernet services in the ONT.
Alarm outputs are available on the OPSU/BBU to monitor the status of the backup battery
(On/Low/Faulty/Missing). The OPSU/BBU indicates its status to the resident with LEDs and
audible alarms and to the outdoor ONT by a signal return connection.
1.2 Components
The OPSU/BBU consists of a dedicated 120Vac to 48Vdcpower supply (OPSU), a Battery
Backup Unit (BBU) and dedicated support cables.
The user interface for the dedicated power supply consists of a single LED to indicate correct
DC output.
The BBU houses a dedicated battery charger to maintain a 12Vdc, 7.2AH lead-acid sealed
battery, battery monitoring and alarm circuitry. It contains four indicator LEDs to provide
operational status at a glance, status audible alarms, and two customer-operation buttons, one
to silence the audible alarm for 24 hours and the second to cause the unit to re-start when a
new battery is installed.

2 IMPORTANT SAFETY NOTES
ONLY qualified installation and repair personnel should service this power supply.
OPSU/BBU Instalation and Operation Manual (IOM), Rev 0.0 Page: 3 of 8

OPSU/BBU Instalation and Operation Manual (IOM), Rev 0.0 Page: 4 of 8
SAVE THESE INSTRUCTIONS - This manual contains important instructions for the
OPSU/BBU units that should be followed during installation and maintenance.
Verify the supplied AC line voltage prior to installation using an AC voltage meter.
Verify branch circuit breaker or fuse on the service feed is correct for the equipment
being installed.
Batteries may produce hazardous currents and may present a burn hazard if
damaged or shorted.
The following precautions should be observed when working on the unit:
1. Remove watches, rings, or other metal objects.
2. Wear protective clothing and eye protection when working with batteries and installing
this equipment.
3. Always carry a water supply to wash eyes and/or skin if exposed to battery electrolyte.
4. Use tools with insulated handles.
5. Examine the packing container for damage. Notify the carrier immediately if damage is
present.
6. Do not disassemble the unit.
7. Do not operate near water or excessive humidity.
8. Keep liquid and foreign objects from getting inside the unit.
9. Do not operate close to gas or fire.
10. Do not operate unit near leaking liquid or if any liquid residue is present.
11. Immediately unplug Power Supply from AC if you see liquid leaking
2.1 Electrical Warnings
Servicing this equipment may require working with protective covers removed and utility
power connected. Use extreme caution during these procedures.
Check that the power cord(s), plug(s), and outlets are in good condition.
No user serviceable components other then the battery are present in the OPSU/BBU.
2.2 Battery Warnings
Danger of explosion if battery is incorrectly connected or replaced. Replacement battery
should be PX12072F2-HG. Replacement battery can be ordered by contacting 1 (800) 472-
2879 or www.gsbattery.com.
Worn-out or damaged batteries are considered environmentally unsafe. Always recycle used
batteries or dispose of the batteries in accordance with all federal, state and local
regulations.
Any gel or liquid emissions from the sealed lead-acid (SLA) battery contain sulfuric acid,
which is harmful to the skin and eyes. Emissions are electrically conductive and corrosive.
Batteries may produce explosive gases. Keep all open flames and sparks away from
batteries.
Batteries contain or emit chemicals known to the State of California to cause cancer and
birth defects or other reproductive harm. Battery post terminals and related accessories
contain lead and lead compounds. Wash hands after handling (California Proposition 65).
Wear protective clothing and eye protection whenever installing, maintaining, servicing, or
replacing batteries.
If any battery emission contacts the skin, immediately and thoroughly wash with water.
Follow approved chemical exposure procedures.
Neutralize any spilled battery emission with the special solution contained in an approved

spill kit or with a solution of one pound Bicarbonate of soda to one gallon of water. Report
chemical spills and seek medical attention if necessary.
Never use un-insulated tools or other conductive materials when installing, maintaining,
servicing or replacing batteries.
A battery showing signs of cracking, leaking, or swelling should be replaced immediately
with a battery of identical type and rating.
2.3 Safety Warning Label
The AC power cord is supplied with two warning labels “Telco Equipment – Do Not Remove” on
the plug and “DO NOT UNPLUG! – Power Supply for Voice, 911 Dialing, and Battery Charging”
attached to the cord.
!DO NOT UNPLUG! – Power Supply
for Voice, 911 Dialing, and Battery Charging.
Figure 2: Warning Labels
If the labels are missing or are not provided for field installation, do not install the
equipment.
3 START-UP
The OPSU/BBU starts once the AC power cord is plugged in. Connecting only the battery will
not start the power supply; the AC supply must be connected. Once the power supply has
started, the unit will operate on the battery if the AC supply voltage fails or the power cord is
disconnected.
