    overvoltage ceases, and it is safe, the ac power returns, the gas tube arrester stops 
    conducting and the thermal circuit breaker reconnects the DPABX. 
    Installation. The surge protector plugs into the standard 3-prong outlet and then 
    provides a receptacle for the ac power cord of the DPABX. The installer should check 
    that the 3-prong ac power receptacle has been properly wired with a safety ground. 
    Devices are commercially available which indicate ifthe outlet has been wired correctly. 
    Note that this type of surge protector can be used on ac circuits equipped with ground 
    fault detectors; however, the ground fault detector may operate when the surge 
    protector shunts to ground.

    Protection for Off-Premises Cables

    Although ac power surge protection is recommended in problem areas, it is 
    mandatory to provide protection on off-premises wiring (trunks, OPXs). Failure to 
    ensure such protection results in unreliable DPABX service (equipment failures) and 
    may invalidate the manufacturer’s warranty. 
    Lightning is an atmospheric effect produced by very high voltages existing for a very 
    short period of time. Currents produced by lightning in the earth’s surface induce large 
    currents in buried telephone cables, typically 100 amps per conductor. A small DPABX 
    with 10 off-premises circuits (trunks or OPXs) can easily experience 20 X 100 = 2000 
    Amps of total induced current flowing in the underground cable. Overhead cables are 
    susceptible to direct strikes of lightning with the same results. 
    Classical PABX Protection. This type of protection uses carbon blocks or gas tube 
    protectors installed where the off-premises wiring enters the building. Figure B-2 
    illustrates the equivalent circuit run-on. When the voltage at node A exceeds the,

    protector breakdown voltage, the protector arcs and the surge current shunts into the 
    protector ground. For electronic DPABXs, 3-element gas tubes are recommended as 
    they have uniform breakdown characteristics for both Tip and Ring.

    Figure B-2 Classical Protection of Trunks/OPXs 
    Incremental Transient Protection. 
    This protection is not necessary for MITEL 
    DPABXs; some installations provide incremental transient protection during the surge 
    rise-time by using a “coupled bonding wire”. This coupled wire is usually No. 10 AWG 
    stranded copper wire tie-wrapped in the center of off-premises cabling and bonded 
    at both the protector ground point and the equipment ground point. Figure B-3 
    illustrates the equivalent circuit. 
    In Figure B-3, the coupled conductor develops an induced voltage in inductor L4 equal 
    to the surge voltage developed in inductor L2. If inductors L2 and L4 are coupled as 
    an ideal transformer, the resultant voltage across the circuit pack is zero. This provides 
    extra protection for the circuit pack. 
    Installation. The installation procedure is critical for safe, reliable protection. 
    Figure B-4 illustrates an installation arrangement using protector blocks, ac surge 
    protection and coupled bonding conductors. Two important items in the installation are: 
    l An approved ground and 
    l Quality power connectors (lug-type) at ground bonding points.

    The following definitions apply to the installation description: 
    l Approved Ground. A cold metallic water pipe. The cold (not hot) water pipe must 
    have a continuous diameter of not less than 1.25 cm (0.5 in.) and be electrically con- 
    nected to the street side of the water meter. Even when the water meter is metallic, a 
    No. 6 AWG bond wire must be placed around the meter. Appropriate clamps must be 
    used to bond the 
    No. 6 AWG wire to the water pipe. The bond wire must be copper.

    l Bonded Connection. A bonded connection implies that appropriate lug type con- 
    nectors are to be used. Such connectors are sized to the wire gauge. 
    l AC Ground. The ac Ground is the green wire (safety ground) which appears at the 
    ac duplex receptacle. 
    l DPABX Chassis Ground. The DPABX Chassis Ground is a No. 6 AWG copper wire 
    which connects from the ground stud on the Power Supply to an approved ground 
    (refer to Approved Ground definition in this Paragraph). 
    l Protector Ground. The Protector Ground is a No. 6 AWG copper wire which con- 
    nects the ground lug on the protector to an approved ground (refer to Approved 
    Ground definition in this Paragraph). 
    Once the installation has been completed, check the following: 
    l Ensure the presence of primary protection for trunks and OPXs. Three-element gas 
    tubes are recommended as they provide consistent breakdown characteristics for 
    both Tip and Ring, thus avoiding metallic voltages between Tip and Ring. Appropri- 
    ate protectors are readily available from various distributors. 
    l Ensure that the NO. 6 AWG wire for the Protector Ground is bonded to an approved 
    ground. The quality of this connection is important; use approved connectors. If a 
    cold water pipe ground is used as the approved ground, then ensure that it is clean 
    (shiny) and free of contaminants at the bonding point.

    							Shipping, Receiving and Installation 
    l Where possible, physically separate the off-premises cabling from the on-premises 
    cabling where the cables meet in the building. Separate ducts or compartmentalized 
    ducts are preferred. 
    Chassis Ground Test. This test should be done before connecting the No. GAWG wire 
    to the ground lug on the Power Supply. 
    l Plug the DPABX ac power cord into the surge protector and the ac receptacle. It is not 
    necessary to power up the DPABX. 
    l Use a good quality, calibrated digital multimeter and prepare to measure any ac voit- 
    age between the DPABX ground lug (on the Power Supply) and the approved ground 
    (the No. 6 AWG wire connected to the cold water pipe). Set the multimeter to the high- 
    est ac voltage range and measure between the Power Supply ground lug and the 
    approved ground. Switch the multimeter from the highest to the lowest voltage 
    range. If voltages greater that 1 .O volt are found, stop and locate an alternative ap- 
    proved ground or refer the problem to an engineering support group. 
    l After ensuring that the voltage between the ground lug on the Power Supply and the 
    approved ground is less than 1 .O volt, set the multimeter to the ohms scale. The me- 
    ter should read less than 5 ohms. If the reading is higher than 5 ohms, stop and take 
    steps to reduce the resistance to 5 ohms (shorten the No. 6 AWG wire and/or clean 
    the surface of the cold water pipe) or refer the problem to an engineering support 
    group. 
    Electrostatic Protection at the Telephone Set 
    8.3 If static is a problem at a specific installation site, it may be necessary to provide some 
    protection on a per-line (telephone set) basis. Such protection is seldom necessary 
    if the cabling between the telephone set and the DPABX is greater than 30 m (100 ft). 
    In cases where the cables are less than 30 m (100 ft), it may become necessary to 
    provide a 30 m (100 f-t) cable loop on a per-line basis (or a MITEL Static Protection 
    Unit, Part Number 9180-067-001-NA), between the telephone set and the DPABX.
