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 spe-
cial disposal instructions.
ELECTROSTATIC INSTRUCTIONS
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 in-
stalled 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 socket-
outlet is located near the equipment and easily accessi-
ble.
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
Position the Total Access PSU (power cords oriented down-
ward) 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 back-
board with four #6 3/4-inch wood screws (not supplied).
Wiring
The Total Access PSU has two cords (AC plug and 4 position 
modular adapter). Insert the Total Access PSU modular

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.
