    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 on the next page) shows you abouthow
    much space your system requires.

    Planning the Installation (Figure 1-1)
    Before installing the common equipment, you should mount a
    Main Distribution Frame (MDF) plywood backboard in a cen-
    trally located spot. A 1/2 sheet of plywood (4’ x 4’) should be
    more than adequate. Mount this backboard using suitable fas-
    teners, 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 7
    feet of the AC receptacle.
    Normally, you install the extension and trunk blocks to the right
    of the Main Cabinet. Telco should also install the RJ21X to the
    right of the Main Cabinet.

    Removing the Cover(Figure 1-2)
    Before wall-mounting, remove the cover on the Main Equipment
    Cabinet.
    1. Unscrew the two captive screws on the front of the cabinet
    cover.
    2. Lift up slightly on the front of the cover — then gently slide
    the cover back to remove it.

    Unpacking the Wall Mount Bracket(Figure 1-3)
    The wall mount bracket and screws are taped to the packing mater-
    ial in the Main Equipment Cabinet box. Unpack the wall mount
    bracket and mounting screws.
    Figure 1-3  WALL MOUNT BRACKET
    Mounting the Wall Mount Bracket(Figure 1-4)
    Mount the wall mount bracket on the MDF in a convenient loca-
    tion, about 12” higher than where you want the bottom of the cabi-
    net to line up.

    Hanging the Cabinet(Figure 1-5)
    1. Hang the Main Equipment Cabinet on the wall mount hang-
    er as shown at right.
    2. Using the remaining two screws that were packed with the
    hanger, secure the cabinet to the plywood backboard.

    Removing the Right Side Panel (Figure 1-6)
    Remove the cabinet right side panel to gain easy access to the
    ground lugs and system cabling. The cabinet has two ground
    connections: ETH (Earth Ground) and PBXG (PBX Ground).
    1. Remove the two screws that secure the right side panel to
    the cabinet.
    2. Carefully slide the right side panel down until it swings clear
    of the cabinet.

    Attaching the Ground Wires (Figures 1-7 and 1-8)
    The system provides two ground terminations. Each ground
    connects from the system to the ground termination using 12
    AWG stranded copper wire (see Figure 1-7).. Use the ETH (Earth Ground) for safety/system ground. You
    mustconnect ETH to a known earth ground.. Use the PBXG (PBX Ground) if you have trunks that require
    telco ground (such as ground start trunks). This ground is not
    required for loop start trunks.
    1. Remove the lug on the ground connection you want to connect.
    2. Following Figure 1-8, run the ground wire(s) through the RFI
    Suppressor Assembly as shown.
    3.For Ear
    th Gr
    ound:
    Run a ground wire from the ETH lug to a known earth ground.
    For PBX Gr
    ound:
    Run a ground wire from the PBXG lug to the telco ground.
    4. Crimp ring terminals as required to the ground wires.
    5. Reinstall and firmly tighten the lug(s) removed in step 1 above. 
    Do not plug in the power cord or reinstall the right sidepanel until all PCB installation and cabling are complete.

    GROUNDING THE CABINET
    !! Install RFI Suppressor Assemblies as shown below !!
    You must install separate RFI Suppressor Assemblies for the
    ground wire, the CPU connections (i.e., mod jack and RS-232
    cables), each trunk cable and each station cable. The suppres-
    sors mustbe mounted inside the cabinet and as close to the
    appropriate PCB as possible.
