NDA-24234 CHAPTER 3 Page 35 Revision 3.0 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.

CHAPTER 3 NDA-24234 Page 36 Revision 3.0 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.” INST CABLE (25P AC-BUS CABLE) LTX PIM BASEU To MDF To MDF E : CHAMP ConnectorCABLE SUPPORT ASSEMBLY LTX

NDA-24234 CHAPTER 3 Page 37 Revision 3.0 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.

CHAPTER 3 NDA-24234 Page 38 Revision 3.0 INSTALLATION PROCEDURE 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.

NDA-24234 CHAPTER 3 Page 39 Revision 3.0 INSTALLATION PROCEDURE This NAP explains the following work items: Confirmation of Equipment Locations Confirmation of Floor Layout Confirmation of Power and Ground Supply Check of Quantity of Equipment Packages Note 1:Confirmation procedures are discussed in Chapter 2 of this manual. Note 2:Be sure to correct any abnormal conditions encountered during installation preparation (missing hard- ware, floor not level, etc.) before proceeding to the next step. NAP-200-001 Sheet 1/2 Installation Preparation Confirmation of Equipment LocationsEnvironmental Confirmation of temperature and humidity. Floor Space Floor Load Equipment Room Floor surface Wall Ceiling Lighting facilities According to the floor layout, confirm that the equipment locations are appropriate. Improper Locations: An open aisle or place where sprinklers are provided. A place where there is a water pipeline. A place where there is a pipeline generating heat and an exhaust for such heat. A location near an exhaust port for corrosive fumes or gas generated from a facility machine. A location near a copying machine or apparatus which dis- sipates heat. A location where the switch will be exposed to direct sun- light. A location near a kitchen facility, etc., from which vapor is generated. A high EMI environment; for example, a location near an elevator motor or X-ray equipment. START AB

CHAPTER 3 NDA-24234 Page 40 Revision 3.0 INSTALLATION PROCEDURE NAP-200-001 Sheet 2/2 Installation Preparation Proper Locations: A dry and clean place. A place that is well ventilated. A sufficiently illuminated room. (200 lux at floor level). A location around which there are no obstructing objects, thus allowing easy maintenance. A place where C.O. lines can be brought in, or local cables can be brought up to the MDF easily. A place where communication and security ground can be obtained as required Confirmation of Power and Ground SupplyConfirm AC voltage and current capacity. Confirm that a Circuit Breaker (NFB) is provided exclusively for the system. Confirm that ground terminals are provided separately from those of the power supply system. Check the Quantity of PackagesCheck the quantity of packages to see if there is a discrepancy with the Packing List. If any equipment is missing, report it to the supplier immediately. A ENDB
