When electrical equipment is in operation, dangerous voltages will be present in certain parts of the equipment.Failure to observe warning notices, incorrect use, or improper use may endanger personnel and equipment and also cause personal injury or physical damage. Before working in the terminal strip area, the equipment must be isolated. Proper and safe operation of the equipment depends on appropriate shipping and handling, proper storage, installation and commissioning, and on careful operation, maintenance and servicing.For this reason only qualified personnel may work on or operate the equipment. Qualified personnel are individuals who: Are familiar with the installation, commissioning, and operation of the equipment and of the system to which it is being connected; Areabletosafelyperformswitchingoperationsinaccordancewithacceptedsafety engineering practices and are authorized to energize and de-energize equipment and to isolate, ground, and label it; Aretrainedinthecareanduseofsafetyapparatusinaccordancewithsafety engineering practices; Are trained in emergency procedures (first aid). Theequipmentdocumentationgivesinstructionsforitsinstallation,commissioning,and operation.However,themanualscannotcoverallconceivablecircumstancesorinclude detailed information on all topics.In the event of questions or specific problems, do not take anyactionwithoutproperauthorization.ContacttheappropriateAREVAtechnicalsales office and request the necessary information.

Theequipmentdocumentationshouldbeconsultedbeforeinstalling, commissioning, or servicing the equipment. Terminalsexposedduringinstallation,commissioningandmaintenancemay present a hazardous voltage unless the equipment is electrically isolated.Theclampingscrewsofallterminalblockconnectors,forfieldwiring,usingM4 screws shall be tightened to a nominal torque of 1.3 Nm. Equipment intended for rack or panel mounting is for use on a flat surface of a Type 1 enclosure, as defined by Underwriters Laboratories (UL). Any disassembly of the equipment may expose parts at hazardous voltage, also electronic parts may be damaged if suitable electrostatic voltage discharge (ESD) precautions are not taken.If there is unlocked access to the rear of the equipment, care should be taken by all personnel to avoid electric shock or energy hazards.Voltage and current connections shall be made using insulated crimp terminations to ensure that terminal block insulation requirements are maintained for safety. Watchdog (self-monitoring) contacts are provided in numerical relays to indicate the health of the device.AREVA T&D strongly recommends that these contacts are hardwired into the substation's automation system, for alarm purposes. Safety SectionP14x/EN SS/G11 (SS) - 5 To ensure that wires are correctly terminated the correct crimp terminal and tool for the wire size should be used. The equipment must be connected in accordance with the appropriate connection diagram.Protection Class I Equipment -Before energizing the equipment it must be earthed using the protective conductorterminal,ifprovided,ortheappropriateterminationofthe supply plug in the case of plug connected equipment.-The protective conductor (earth) connection must not be removed since the protection against electric shock provided by the equipment would be lost. -Whentheprotective(earth)conductorterminal(PCT)isalsousedto terminatecablescreens,etc.,itisessentialthattheintegrityofthe protective(earth)conductorischeckedaftertheadditionorremovalof such functional earth connections.For M4 stud PCTs the integrity of the protective (earth) connections should be ensured by use of a locknut or similar. Therecommendedminimumprotectiveconductor(earth)wiresizeis2.5 mm (3.3 mm for North America) unless otherwise stated in the technical data section of the equipment documentation, or otherwise required by local or country wiring regulations. The protective conductor (earth) connection must be low-inductance and as short as possible. All connections to the equipment must have a defined potential.Connections that arepre-wired,butnotused,shouldpreferablybegroundedwhenbinaryinputs andoutputrelaysareisolated.Whenbinaryinputsandoutputrelaysare connected to common potential, the pre-wired but unused connections should be connected to the common potential of the grouped connections. Before energizing the equipment, the following should be checked: -Voltage rating/polarity (rating label/equipment documentation); -CT circuit rating (rating label) and integrity of connections; -Protective fuse rating; -Integrityoftheprotectiveconductor(earth)connection(where applicable); -Voltage and current rating of external wiring, applicable to the application.Accidental touching of exposed terminalsIf working in an area of restricted space, such as a cubicle, where there is a risk of electricshockduetoaccidentaltouchingofterminalswhichdonotcomplywith IP20 rating, then a suitable protective barrier should be provided. Equipment use Iftheequipmentisusedinamannernotspecifiedbythemanufacturer,the protection provided by the equipment may be impaired. Removal of the equipment front panel/coverRemovaloftheequipmentfrontpanel/covermayexposehazardousliveparts, which must not be touched until the electrical power is removed. SS P14x/EN SS/G11Safety Section (SS) - 6 UL and CSA/CUL listed or recognized equipment TomaintainULandCSA/CULListing/RecognizedstatusforNorthAmericathe equipment should be installed using UL or CSA Listed or Recognized parts for the followingitems:connectioncables,protectivefuses/fuseholdersorcircuit breakers, insulation crimp terminals and replacement internal battery, as specified in the equipment documentation. For external protective fuses a UL or CSA Listed fuse shall be used. The Listed type shall be a Class Jtime delay fuse, with a maximum current rating of 15 A and a minimum d.c. rating of 250 Vd.c., for example type AJ T15. Where UL or CSA Listing of the equipment is not required, a high rupture capacity (HRC) fuse type with a maximum current rating of 16 Amps and a minimum d.c. rating of 250 Vd.c. may be used, for example Red Spot type NIT or TIA. Equipment operating conditions Theequipmentshouldbeoperatedwithinthespecifiedelectricaland environmental limits. Current transformer circuits Do not open the secondary circuit of a live CT since the high voltage produced maybelethaltopersonnelandcoulddamageinsulation.Generally,forsafety, the secondary of the line CT must be shorted before opening any connections to it. Formostequipmentwithring-terminalconnections,thethreadedterminalblock for current transformer termination has automatic CT shorting on removal of the module.ThereforeexternalshortingoftheCTsmaynotberequired,the equipment documentation should be checked to see if this applies. Forequipmentwithpin-terminalconnections,thethreadedterminalblockfor current transformer termination does NOT have automatic CT shorting on removal of the module. External resistors, including voltage dependent resistors (VDRs) Where external resistors, including voltage dependent resistors (VDRs), are fitted to the equipment, these may present a risk of electric shock or burns, if touched. Battery replacement Where internal batteries are fitted they should be replaced with the recommended typeandbeinstalledwiththecorrectpolaritytoavoidpossibledamagetothe equipment, buildings and persons. Insulation and dielectric strength testing Insulation testing may leave capacitors charged up to a hazardous voltage.At the end of each part of the test, the voltage should be gradually reduced to zero, to discharge capacitors, before the test leads are disconnected. Insertion of modules and pcb cards ModulesandPCBcardsmustnotbeinsertedintoorwithdrawnfromthe equipment whilst it is energized, since this may result in damage. Insertion and withdrawal of extender cards Extender cardsare availablefor someequipment. Ifanextender cardis used, this should not be inserted or withdrawn from the equipment whilst it is energized.This is to avoid possible shock or damage hazards.Hazardous live voltages may be accessible on the extender card. SS Safety SectionP14x/EN SS/G11 (SS) - 7 External test blocks and test plugs Great care should be taken when using external test blocks and test plugs such astheMMLG,MMLBandMiCOMP990types,hazardousvoltagesmaybe accessiblewhenusingthese.*CTshortinglinksmustbeinplacebeforethe insertion or removal of MMLB test plugs, to avoid potentially lethal voltages. *Note:When a MiCOM P992 Test Plug is inserted into the MiCOM P991 Test Block, the secondaries of the line CTs are automatically shorted, making them safe. Fiber optic communication Where fiber optic communication devices are fitted, these should not be viewed directly.Opticalpowermetersshouldbeusedtodeterminetheoperationor signal level of the device. Cleaning The equipment may be cleaned using a lint free cloth dampened with clean water, when no connections are energized.Contact fingers of test plugs are normally protected by petroleum jelly, which should not be removed. SS 5.DE-COMMISSIONING AND DISPOSAL De-commissioning The supply input (auxiliary) for the equipment may include capacitors across the supply or to earth.To avoid electric shock or energy hazards, after completely isolatingthesuppliestotheequipment(bothpolesofanydcsupply),the capacitors should be safely discharged via the external terminals prior to de-commissioning. Disposal Itisrecommendedthatincinerationanddisposaltowatercoursesisavoided.Theequipmentshouldbedisposedofinasafemanner.Anyequipment containingbatteriesshouldhavethemremovedbeforedisposal,taking precautionstoavoidshortcircuits.Particularregulationswithinthecountryof operation, may apply to the disposal of the equipment. 6.TECHNICAL SPECIFICATIONS FOR SAFETY Unless otherwise stated in the equipment technical manual, the following data is applicable. 6.1Protective fuse rating Therecommendedmaximumratingoftheexternalprotectivefuseforequipmentsis16A, high rupture capacity (HRC) Red Spot type NIT, or TIA, or equivalent.The protective fuse should be located as close to the unit as possible.
