Shipping, Receiving and Installation 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.

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, 200 B-2 Revision 0 9104-091-200-NA Issue 5
System Grounding and Surge Protection Requirements 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. CIRCUIT PACK 1;--‘-:1:1’1:~’ ! Ll APPROVED GROUND L3 f/7 AP- PROVED GROUND 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. 910449 l -200-NA Issue 5 Revision 0 200 B-3
Shipping, Receiving and Installation CIRCUIT PACK APPROVED APPROVED GROUND GROUND DD0064 Figure B-3 Protection with “Coupled Bonding Conductor” 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. 200 B-4 Revision 0 9104-09,1-200-NA Issue 5

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. 9104-091-200-NA Issue 5 Revision 0 200 B-5
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. 200 B-6 Revision 0 9104-091-200-NA Issue 5
