1. GENERAL
2. DESCRIPTION
This practice provides installation and maintenance
procedures for the ADTRAN™ Total Access 750/850
Power Supply/Battery Charger. Figure 1 is a front
and back illustration of the PS/BC.
The AC/DC Power Supply/Battery Charger provides
-54 VDC to the Power Supply Unit in the TA 750/850
Chassis. The PS/BC receives 115 VAC through a
standard plug and wall socket. The unit works in
conjunction with an optional ADTRAN backup
battery pack, P/N 1175044L1, L2, L3. In this
arrangement, the PS/BC maintains the battery at peak
charge of -54V. If AC power is lost, the unit
automatically transfers power from the battery pack
without interrupting service. When AC power returns,
the unit switches back to AC power and recharges the
battery to peak charge.

There are three installation arrangements:
Optional Mounting Locations
•
•
•
Wallmount.
Mounted to TA 750/850 chassis.
Mounted to backup Battery Pack (L1 only).
As an optional installation arrangement, the PS/BC
unit can mount on either side of the TA 750/850
chassis, or the top of the battery pack (wall or rack
orientation) which has space for two PS/BCs. These
locations all have pre-threaded inserts designed for the
PS/BC. For installation, four #6-32 by 3/8-inch
machine screws are provided.
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.
CAUTION
Refer to Figure 2. Installation is as follows:
When mounting to the battery pack, using
screws longer than 3/8-inch could damage
batteries.
1. Determine the preferred layout and ensure the
socket-outlet 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.
