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.
