ADTRAN 750 specifications Wallmounting, Optional Mounting Locations

Page 3
Wallmounting

There are three installation arrangements:

Wallmount.

Mounted to TA 750/850 chassis.

Mounted to backup Battery Pack (L1 only).

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.

Refer to Figure 2. Installation is as follows:

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.

Optional Mounting Locations

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.

CAUTION

When mounting to the battery pack, using screws longer than 3/8-inch could damage batteries.
