Unpacking
Unpack the equipment and check it against your equipment lists.
Inspect for physical damage. If you are not sure about a compo-
nent’s function, review the Product Description Manual. Contact
your Sales Representative if you have additional questions.
Have the appropriate tools for the job on hand, including: a test
set, a punch down tool and a digital voltmeter.
Before Installing
Make sure you have a building plan showing the location of
the common equipment, extensions, the telco demarcation and
earth ground.  In addition, the installation site must meet the
requirements outlined in the Standard Practices Manual.
Site Requirements
The common equipment is contained in the wall-mounted Main
Equipment Cabinet. Choose a central location for the cabinet
that allows enough space for the equipment — and provides
enough room for you to comfortably work. The Installation
Layout (Figure 1-1) shows you abouthow much space your sys-
tem requires.

System Load Factor Calculations
The combination of extensions, trunks, Digital Door Boxes and
DSS Consoles you can connect to your system may be limited by
the System Load Factor. Use the DS1000 System Load Factor
Calculationschart at right to verify your system’s configuration.
To check your system configuration:
1. Indicate the quantity for each item installed in the 
Qty
column.
2. For each item, multiply the 
Qty
times and 
Load Factor
and
enter the value in the 
Total Load
column.3. Add all the values in the 
Total Load
column and enter the
value in row 1.
4. Compare the entry in row 
2to your entry in row 
1. Row 1
must always be equal to or less than the entry in row 2.
Do not operate your system if the System Load Factortotal (row 1) exceeds the allowable load of 30 (row 2).

INSTALLING THE CABINET
Planning the Installation (Figure 1-1)
Before installing the common equipment, you should mount a
Main Distribution Frame (MDF) plywood backboard in a centrally
located spot. A 1/2 sheet of plywood (4’ x 4’) should be more than
adequate. Mount this backboard using suitable fasteners, taking
care to adhere to standard installation practices and local codes.
The equipment cabinet requires a three-prong, dedicated
110 VAC 60 Hz circuit (NEMA 5-15 receptacle) located within
4 1/2’ feet of the AC receptacle.
Normally, you install the extension blocks and trunk/AUX jacks
to the right of the Main Cabinet.
!! Important !!
Local codes may prohibit you from installing extensions, trunksand optional equipment in the same blocks.

Hanging the Cabinet(Figure 1-3)
1. Screw suitable fasteners 11 3/16” apart in a convenient loca-
tion on the MDF. Be sure to leave the fasteners “backed out”
about 3/16” from the MDF backboard.
2. Hang the cabinet as shown in Figure 1-3.

GROUNDING THE CABINET
Attaching the Ground Wire (Figure 1-4)
!!  Important  !!
You must connect your system to a known earth ground accord-ing the following instructions.
1. Loosen the lug on the cabinet’s ground connection.
2. Following Figure 1-4, run a 12 AWG stranded copper wire
from the ground lug to a known earth ground.
4. Firmly retighten the lug loosened in step 1 above.
