1. GENERAL
This practice provides installation and maintenance procedures for the ADTRAN ™ AC/DC Power Supply and Battery Charger (PS/BC). Figure 1 is a front and back illustration of the PS/BC.
Revision History
This is the initial release of this document. Future revisions will be made in this subsection.
Features
Features of the PS/BC, P/N 1175043L3, include the following:
•Compact design.
•Versatile mounting arrangements.
•All mounting hardware included.
•Built-in fuse.
•Multi-feature status LED.
•Modular connections.
•Positive ground.
•Uninterrupted power output (if battery backup connected).

•Complies with GR-1089-CORE and GR-63-CORE.
2. DESCRIPTION
The AC/DC PS/BC provides -54 VDC to the Power Supply unit in various supported product systems. The PS/BC receives 115 VAC through a standard plug and wall socket. Some of the more common supported ADTRAN systems include:
•Total Access 750/850
•Total Access OPTI-3
•MX2800/2810
•NIU3 (single mount housing, 3-slot shelf, 12-slot shelf)
•Battery Backup Units
Refer to your product documentation to verify compatibility with the PS/BC.
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
(1)This device may not cause harmful interference, and
(2)This device must accept any interference that may cause undesired operation.
Changes or modifications not expressly approved by ADTRAN could void the user’s authority to operate this equipment.
Fuse
A 3 Amp fuse on the back panel protects the unit from over current. The fuse isolates the AC input from the power supply in the event of a fault. The fuse is replaced by twisting the

3. INSTALLATION
CAUTION
This equipment MUST only be installed in a DC-C bonding and grounding environment per Telcordia GR-1089-CORE, Issue 3. It may not be utilized in a DC-I (isolated) bonding and grounding environment.
SAFETY INFORMATION
When using your telephone equipment, please follow these basic safety precautions to reduce the risk of fire, electrical shock, or personal injury:
1.Do not use this product near water, such as a bathtub, wash bowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool.
2.Avoid using a telephone (other than a cordless-type) during an electrical storm. There is a remote risk of shock from lightning.
3.Do not use the telephone to report a gas leak in the vicinity of the leak.
4.Use only the power cord, power supply, and/or batteries indicated in the manual. Do not dispose of batteries in a fire; they may explode. Check with local codes for special disposal instructions.
ELECTROSTATIC INSTRUCTIONS
C A U T I O N !
SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
CAUTION
Electronic equipment can be damaged by static electrical discharge. Before handling equipment, wear an antistatic discharge wrist strap to prevent damage to electronic components. Place equipment in antistatic packing material when transporting or storing. When working on equipment, always place them on an approved antistatic mat that is electronically grounded.
After unpacking the unit, inspect it for damage. If damage is noted, file a claim with the carrier then notify ADTRAN Customer Service.
MOUNTING AND WIRING INSTRUCTIONS
The following are mounting instructions for the AC/DC PS/BC when utilized with some of the various ADTRAN product systems. If your ADTRAN system is not listed in this section, please refer to the documentation provided with your ADTRAN product system for more detailed instructions.
Wallmounting
For the wallmount arrangement, the PS/BC is normally installed on the designated 3/4-inch or thicker plywood with four #6 by 3/4-inch flat-head wood screws. Installation is as follows:
1.Determine the preferred layout and ensure the socketoutlet is located near the equipment and easily accessible.
2.Ensure the unit is plumb, then mark through the four screw holes to identify where the pilot holes will be drilled.
3.Using a 1/16-inch bit, drill pilot holes at the marked locations.
4.Mount the unit using the pan-head screws.
5.Route and connect all cabling to the appropriate device. Use cable tie-downs as needed.
6.Connect the ground stud using the most direct route to a known equipment ground source.
Total Access 750/850
Mounting
Mount the power supply on the left side of the Total Access 750/850 shelf (next to the battery cover hinge) for battery backup installations (P/N 1175044L2 and 1175044L4)
Position the Total Access PSU (power cords oriented downward) and align all four holes (on the tabs at the corner of the Total Access PSU) with the four available machined holes on either side of the Total Access 750/850. Use four #6 3/8-inch machine screws (provided) to secure the Total Access PSU. Alternately, the Total Access PSU can be mounted to a backboard with four #6 3/4-inch wood screws (not supplied).
Wiring
Before beginning the wiring connection, verify that the Total Access 750/850 and the AC/DC Power Supply and Battery Charger are properly grounded with the required supplemental ground.
Power should be the last connection made during installation.
The Total Access PSU has two cords (AC plug and 4 position modular adapter). Insert the Total Access PSU modular
