    10.2 Cables Between The PBX And MDF
    Regarding lines, trunks, and NCU (PFT), 25P shielded the PBX and the MDF are connected using cables with
    a CHAMP (Amphenol) connector at one end.

    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 IN-
    STALLATION” and observe the precautions while performing the installation.

    INSTALLATION PROCEDURE
    2. PRECAUTIONS BEFORE BEGINNING INSTALLATION
    2.1 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 ar-
    rangement, noise radiation from each cable is prevented. For the installation method, refer to NAP-200-
    013: “Cable Running from the Module Group to MDF, 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.
    NAPs NAP-200-001 through NAP-200-018 follow Figure 3-2. These NAPs should be followed sequentially
    when performing the installation. Individual steps, such as installation of SMDR, can be performed indepen-
    dently by referring to the corresponding NAP.
