CHAPTER 3 INSTALLATION PROCEDURE
1. GENERAL
This chapter explains the procedures for installing the PBX, the Maintenance Administration Terminal (MAT),
Desk Consoles, and various types of terminal equipment (single line telephones, D
terms, Data Modules, etc.).
The procedures explained in this chapter are shown in Figure 3-1.
Before beginning the installation, thoroughly read Section 2., “PRECAUTIONS BEFORE BEGINNING
INSTALLATION” and observe the precautions while performing the installation.

INSTALLATION PROCEDURE
2. PRECAUTIONS BEFORE BEGINNING INSTALLATION
Outline
1. Before beginning the installation, check to see if the installation requirements (grounding, the quantity and
kind of installation cables, etc.) are all present by referring to Chapter 2 of this manual.
2. For a standard installation, the system is installed on a free-access floor, so no explanations are provided
pertaining to cable racks and cable ducts.
3. The PBX is connected to the MDF by use of 25-pair shielded cables as the installation cables. Each of these
installation cables is grounded at the cable support assembly of the BASEU as shown below. By this
arrangement, noise radiation from each cable is prevented.
For the installation method, refer to NAP-200-012: “Cable Running from the PBX to MDF, ATTCON,
MAT and SMDR”.

INSTALLATION PROCEDURE
4. As the cable to be run between the PBX and the Rectifier, use a CV cable (600 V Crosslinked Polyethylene
Insulated PVC Sheathed Cable) as the circumstance permits. Compared with an ordinary IV cable (600 V
PVC Insulated Cable) the CV cable is stronger because of its thicker cover. Thus, it is suitable to run along
the free-access floor where it is difficult to protect the cable from damage.
Also, for easy identification of different cables, use cables of different colors as follows:
 –48 V: Blue (White)
 GND: Red (Black)
 E: Green
Note:The color shown in (  ) is applicable to the UL Specification.

3. INSTALLATION PROCEDURE
The flowchart in Figure 3-2 shows the steps of the installation procedure. Each step is assigned a NAP number.
NAP-200-001 through NAP-200-017 follow Figure 3-2. These NAPs should be followed sequentially when
performing the installation. Individual steps, such as installation of SMDR, can be performed independently by
referring to the corresponding NAP.

This NAP explains the procedures for marking, drilling and other necessary work when the PBX is to be installed
on a free-access floor by either one of the following three methods.
 Securing the PBX directly onto the floor
 Securing the PBX with the special stand
 Securing the PBX with the floor elevation
This NAP also explains the procedures for marking, leveling and drilling for MDF, Power Equipment, and Peripheral
Equipment (See Section 4).
Note:Kinds of Anchor Bolts
Various types of anchor bolts are available; the type of bolt to be used depends on the application. Sleeve
expansion-type anchor bolts are generally preferred for the PBX installation. Table 002-1 shows anchor
bolt specifications.
