Step 1 Plan Your System
Draw a floor plan of your business, showing the location of the network interface jacks,
where your local telephone lines come into the building or office. Install your controller
close to these jacks. Be sure an AC outlet not controlled by a switch is available.
Show on the floor plan the location of each telephone in your system and the distances of
the wiring run from the controller to each telephone location.
Below is a sample floor plan to guide you in making your own floor plan.
NOTE: If you need to install
but not more than 1000 feet from the controller, an in-range, out-of-building (IROB) protection device is required. Contact your AT&T representative and order part number 31304.

Step 2 Check Outlet Grounding
Your

and central office line voltage surges caused by lightning strikes or other power
anomalies, provided the system is properly grounded.
Using a circuit tester, check (or have checked by a qualified technician) the outlet into
which your
any of these faults, have this corrected before installation of the control unit:
— open ground
— reversed polarity
— open hot
If necessary, have a qualified electrician repair the electrical outlet in the manner
specified by the applicable electrical codes to prevent service interruption and continue
warranty protection. If you have two-wire outlets with no ground wire, a non-switched,
three-wire grounded outlet should be installed.

Step 3 Mount Controller
You will need the following to mount your controller on the wall:
eight screws
●
For drywall, tile, or masonry use size 6 to 8 x ¾ inch plastic anchors with size 6 x 1 inch
slotted screws. For wood, use size 6 x 1 inch slotted round head wood screws. These screws
are available at your local hardware store.
●
12-inch ruler
●
flathead screwdriver
●
drill with the drill bit recommended for the type of screws
●
pencil
Choose a location within five feet of the network interface jacks, where the local telephone
company lines enter the building, and within five feet of a grounded (three-prong) AC outlet
that is not controlled by a switch. The power supply unit will be plugged into this outlet and
the controller connected to the power supply unit. The controller and power supply unit must be
within six inches of each other with the power supply on the left side of the controller.
NOTE: Try to position the controller so that there is an additional two feet of free wall space to
the right to allow for future expansion.
Be sure that the controller is in a well-ventilated area with a temperature range of 40° F to
100° F, and free of excessive dust and moisture. The controller should be at least two feet
from the floor.
■
A. Mount the Power Supply Unit
Mount the power supply unit on the far left side of the chosen location, making sure it is
within five feet of a grounded AC outlet not controlled by a switch.
Drill two holes 4¼ inches apart and install two mounting screws. Loosen the screws enough to
hang the power supply unit. Mark the location of the two holes on the bottom of the unit and
remove the unit from the wall. Drill two more holes. Reinstall the power supply unit onto the
wall. Insert the two bottom mounting screws, and firmly tighten all four screws.

■
B. Mount Controller on Wall
If you are installing the 2448 expansion unit when you first put in your
SPIRIT
system,
follow the instructions provided with the expansion unit instead of those in part B.
Be sure to mount the controller within six inches of where the power cable will connect to the
power supply unit. Make two level marks 11 inches apart. Drill holes at these marks and install
two of the eight mounting screws so that the screw heads are about 3/16 inches from the wall.
NOTE: If a ruler is unavailble, the panel (front cover) can be used as a guide. Remove the panel
from the controller (see panel removal instructions in part F on page 6). Along the top edge of
the panel there are four little ribs. The two ribs closest to each edge of the panel are 11 inches apart.
Temporarily hang the controller on the mounting screws, by placing the two keyholes on the
top back of the controller on the screws and pulling down gently. Make a mark at the center
of each slot on the bottom back of the controller. Remove the controller by lifting it up and away
from the mounting screws. Drill a hole at each of the two marks. Install two more mounting
screws so that the screw heads are about 3/16” from the wall.
Place the controller on all four mounting screws and pull down. Firmly tighten the bottom
mounting screws.
Write the date on the date installed label (DATE INST:) located on the label sheet and place it
on the left side of the controller.
NOTE: The controller and power supply may be installed on a table or desktop without mounting.
Take special care to reduce the possibility of the equipment moving or falling.
■
C. Install Line and Station Cards
If you purchased additional line and/or station cards, install them in the controller following
the instructions provided with the cards.
