    SECTION 1
    GENERAL
    INFORMATION
    This section provides the requirements for installing the system. The installer should be
    familiar with this section before installing the system.
    SECTION 2
    SITE
    PREPARATION
    The technician should plan the installation before actual work begins. Advanced planning
    will minimize time, cost and disruption of the customer’s business activities. Additional
    benefits include flexibility for changes and expansion, efficient maintenance and increased
    customer satisfaction.
    Precautionary Information
    The following warnings shall be observed during installation:
    1. Never install telephone wiring during a lightning storm.
    2. Never install telephone jacks in wet locations unless the jack is specifically designed for
    wet locations
    3. Never touch uninsulated telephone wires or terminals unless the telephone line has
    been disconnected at the network interface.
    4. Use caution when installing or modifying telephone lines.
    Site Survey
    Inmost cases, a survey of the customer’s premises is needed to develop cost estimates of
    the installation. Preliminary information is used to determine the placement of the Main
    Distribution Frame (MDF). A second visit to the site may be necessary to obtain the exact
    dimensions of the area selected for MDF, cable lengths and possible IDF (intermediate
    Distribution Frame) locations.
    Site Limitations
    Installation of a telephone system is seldom a routine procedure. The uniqueness of each
    customer’s situation requires a tailored approach to each job. In selecting a permanent site
    for the MDF, the technician may encounter problems such as, but not limited to the following:
    !Limited space is available and must be used regardless of its suitability.
    !The available space may be adequate, but may pose one or more environmental
    hazards.
    !The proposed location has limitations. Such as insufficient lighting or the lack of a
    suitable ground for grounding the KSUs.
    Whatever the nature of the adversities encountered, the technician must make the
    necessary decisions to arrive at the best possible solution for installing the equipment. It is
    beyond the scope of this document to cover all possible situations, precautions and actions.

    A6-506000-642-01
    Site Selection Conditions
    KSU Installation Site
    The following conditions should be met at the site selected for the KSU.
    !The KSUs should be wall mounted to protect against accident or flooding.
    !The KSU should not be located directly beneath pipes, due to the possibility of leaks or
    condensation causing damage to the equipment.
    !The area where the KSU is to be located must be free of corrosive and inflammable
    gases, excessive chemical or industrial dusts and other materials that could cause a
    hazard to personal or to the proper functioning of the equipment.
    !Operating ambient temperature and humidity must be within the limits specified in
    Section 2.6 – Environmental Conditions in this chapter.
    !The operation of the system is virtually noiseless and allows a wide selection of
    installation sites. Care should be taken to ensure the KSUs do not present a hazard to
    office traffic. For purposes of economy, a central location to minimise cabling is
    often used.
    !The basic KSU weighs approximately 4 Kg. Select a strong wall for mounting purposes.
    !Place the KSU according tot he following spacing specifications
    • Space distance between the KSU and the ceiling: 50 cm or more
    • Space distance on both sides of the KSU: 30 cm or more
    • Space distance on front of KSU: 50 cm or more
    !Avoid connection of the KSU to an AC receptacle used in common with any other
    device (computer, facsimile machine, copier, etc.)
    !Ensure that any AC Outlet to be connected is properly grounded.
    !Avoid connection of KSU near radio receivers or electrical noise generators (e.g.
    welding equipment, machinery).
    CAUTION
    1. The socket outlet shall be installed near the equipment and shall be easily accessible.
    2. Plug the system into the mains supply (240 V ac) before terminating a
    telecommunications network conductor to the system.
    3. Danger of explosion if batteries are incorrectly replaced. Replace only with the same or
    equivalent type recommended by the manufacturer. Dispose of used batteries
    according to the manufacturers instructions
    Multiline Telephone Installation Site
    The following conditions should be met at the site selected for MLTs.
    !Ensure the cable length and line resistance (loop), between the KSU and the
    telephones comply with the specifications shown in Table 1-1: Multiline Telephone Loop
    Resistance and Cable Length Multiline Telephone Loop Resistance and Cable Length.
    !Some devices require an external power supply. Select a place where they can be
    easily connected to an AC outlet.
    !Telephones intended for handsfree use should be kept away from areas subject to loud
    noise or echoing.

    SECTION 3
    INSTALLING THE
    KEY SERVICE
    UNIT (KSU)
    Installation Precautions
    Before installation and cabling of the KSU, observe the below precautions.
    !Before starting the work, be sure the KSU power switch is OFF and disconnect the
    power cord from the AC outlet.
    !Do not directly touch the soldered surfaces of the KTUs with you hands.
    !Extreme care must be taken to avoid STATIC DISCHARGE when handling ICs and
    KTUs – an earthed wrist strap must be worn.
    The Key Service Unit
    The B614-B13 KSU is the system cabinet that houses a power supply, battery backup and
    fixed slots for installing option/expansion cards. The KSU is wall mounted. (Refer to Figure
    2-1:: Front View of a KSU, Pg 25.)

    Removing the KSU Cover
    Before wall mounting the KSU, the KSU cover must be removed. Below is a diagram
    showing how to remove the cover of the KSU.
    1. Remove the cover by loosening the two bottom screws with a philips head screwdriver
    (the screws remain in the cover to keep from misplacing them). Pull the cover away
    from the KSU and lift upward.
    2. To replace the cover, locate the tabs on the top of the cover into the slots in the top of
    the base and then push the bottom of the cover inwards. Tighten the two cover screws.
