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.

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

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 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

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
