  3.2 Labels

  See Safety Guide (SFTY/4L M) for typical equipment labeling
  information.

  4. INSTALLING, COMMISSIONING AND SERVICING

  Equipment connections Personnel undertaking installation,
  commissioning or servicing work on this equipment should be aware
  of the correct working procedures to ensure safety. The equipment
  documentation should be consulted before installing, commissioning,
  or servicing the equipment. Terminals exposed during installation,
  commissioning and maintenance may present a hazardous voltage
  unless the equipment is electrically isolated. 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 should 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.
  Schneider Electric Energy strongly recommends that these contacts
  are hardwired into the substation’s automation system, for alarm
  purposes. 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 conductor terminal, if provided, or the appropriate
  termination of the

• P111Enh/EN SS v1.3

  Safety Section (SS) — 4

  SS

  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.

  — When the protective (earth) conductor terminal (PCT) is also
  used to terminate cable screens, etc., it is essential that the
  integrity of the protective (earth) conductor be checked after the
  addition or removal of 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.

  The recommended minimum protective conductor (earth) wire size
  is 2.5 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 are pre-wired, but not used, should
  preferably be grounded when binary inputs and output relays are
  isolated. When binary inputs and output relays are 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; — Integrity of the
  protective conductor (earth) connection (where

  applicable); — Voltage and current rating of external wiring,
  applicable to the application.

  Accidental touching of exposed terminals If working in an area
  of restricted space, such as a cubicle, where there is a risk of
  electric shock due to accidental touching of terminals which do not
  comply with IP20 rating, then a suitable protective barrier should
  be provided.

  Equipment use If the equipment is used in a manner not specified
  by the manufacturer, the protection provided by the equipment may
  be impaired.

  Removal of the equipment front panel/cover Removal of the
  equipment front panel/cover may expose hazardous live parts, which
  must not be touched until the electrical power is removed.

  UL and CSA listed or recognized equipment To maintain UL and CSA
  approvals the equipment should be installed using UL and/or CSA
  listed or recognized parts of the following type: connection
  cables, protective fuses/fuse holders or circuit breakers,
  insulation crimp terminals, and replacement internal battery, as
  specified in the equipment documentation.

  Equipment operating conditions The equipment should be operated
  within the specified electrical and environmental limits.

• Safety Section

  P111Enh/EN SS v1.3 (SS) — 5

  SS

  Current transformer circuits Do not open the secondary circuit
  of a live CT since the high voltage produced may be lethal to
  personnel and could damage insulation. Generally, for safety, the
  secondary of the line CT must be shorted before opening any
  connections to it. For most equipment with ring-terminal
  connections, the threaded terminal block for current transformer
  termination has automatic CT shorting on removal of the module.
  Therefore external shorting of the CTs may not be required, the
  equipment documentation should be checked to see if this applies.
  For equipment with pin-terminal connections, the threaded terminal
  block for 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 type and be installed with
  the correct polarity to avoid possible damage to the 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 Modules and PCB cards must
  not be inserted into or withdrawn from the equipment whilst it is
  energized, since this may result in damage.

  Insertion and withdrawal of extender cards Extender cards are
  available for some equipment. If an extender card is 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.

  External test blocks and test plugs Great care should be taken
  when using external test blocks and test plugs such as the MMLG,
  MMLB and MiCOM P990 types, hazardous voltages may be accessible
  when using these. *CT shorting links must be in place before the
  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. Optical
  power meters should be used to determine the operation or 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.

  Maintenance and installation For safety reason, no work must be
  carried out on the P111Enh until all power sources to the unit have
  been disconnected

  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 isolating the
  supplies to the equipment (both poles of any dc supply), the
  capacitors should be safely discharged via the external terminals
  prior to de-commissioning.

  Disposal It is recommended that incineration and disposal to
  water courses is avoided. The equipment should be disposed of in a
  safe manner. Batteries should be removed from any equipment before
  its disposal, taking precautions to avoid short circuits.
  Particular regulations within the country of operation, may apply
  to the disposal of the equipment.

  6. TECHNICAL SPECIFICATIONS FOR SAFETY Where UL Listing of the
  equipment is not required the recommended fuse type is a high
  rupture capacity (HRC) type with a maximum current rating of 16
  Amps and a minimum DC rating of 250 Vdc, for example the Red Spot
  NIT or TIA type.

  To maintain UL and CUL Listing of the equipment for North
  America a UL Listed fuse shall be used. The UL Listed type shall be
  a Class J time delay fuse, with a maximum current rating of 15 A
  and a minimum DC rating of 250 Vdc, for example type AJT15.

  The protective fuse should be located as close to the unit as
  possible.

  15. CURVES 15.1 General

  Although the curves tend towards infinite when the current
  approaches Is (general threshold), the minimum guaranteed value of
  the operating current for all the curves with the inverse time
  characteristic is 1.1 Is (with a tolerance of 0.05 Is).

  15.1.1 Inverse Time Curves

  The first phase (or earth) overcurrent stage can be selected
  with an inverse definite minimum time (IDMT) characteristic. The
  time-delay is calculated using a mathematical formula.

  In all, there are eleven IDMT characteristics available.

  The mathematical formula applicable to the first ten curves
  is:

  +

  = cP

  GsG

  kTMSt

  Where:

  t Operation time

  k, c, , P Constant (see table)

  G Value of measured current

  RXIDG Curves

  RXIDG curves can be selected on P111Enh Model E with wide earth
  current (corresponding to Cortec model number P111xxx4xxxxxxxxxx
  )

  The first earth thresholds can be selected with dedicated RXIDG
  curves.

  The curves available follow the formula:

  t = 5.8 1.35 * ln ( 1/ (k * Is/I))

  Where:

  t = tripping time

  k = coefficient (from 0.3 to 1, by steps of 0.01)

  Is = value of the programmed threshold (Pick-up value)

  I = value of measured current

  In order to be compliant with the Netmanagement specifications
  the relay must be used with:

  An earth current range 0.01 Ion to 12 Ien

  A rated current wiring 1A

  A core balanced CT with a ratio 25/1.

  15.1.2 Reset Timer

  The first phase and earth overcurrent stages and the second
  phase overcurrent stage are provided with a timer hold facility: «t
  Reset».

  The value that is set for this reset timer corresponds to the
  minimum time during which the current value needs to be lower than
  95% of the phase (or earth) threshold before the corresponding
  phase (or earth) time-delay is reset.

  Note: There is an exception to this rule when the protection
  triggers. In fact, in that case, the time-delays (tI> and
  tIe>) are immediately reset.

  The value of the Reset Timer depends on the type of timer
  associated with the pick-up of the first phase (or earth)
  stage.

  It may be set to a definite time value or to an inverse definite
  minimum time characteristic (IEC/IEEE/ANSI curves only). This may
  be useful in certain applications, for example when grading with
  upstream electromechanical overcurrent relays that have inherent
  reset time-delays.

  The second and third earth fault stages have only a definite
  time reset.

  A possible situation where the reset timer may be used is to
  reduce fault clearance times where intermittent faults occur.

  An example may occur in a cable with plastic insulation. In this
  application it is possible that the fault energy melts the cable
  insulation, which then reseals after clearance, thereby eliminating
  the cause for the fault. This process repeats itself to give a
  succession of fault current pulses, each of increasing duration
  with reducing intervals between the pulses, until the fault becomes
  permanent.

  When the reset time of the overcurrent relay is set to its
  minimum, the relay will be repeatedly reset and will not be able to
  trip until the fault becomes permanent. By using the reset timer
  hold function the relay will integrate the fault current pulses,
  thereby reducing the fault clearance time.

  The mathematical formula applicable to the five curves is:

  = p

  GsG

  trRTt1

  Where:

  t Reset time

  tr, p Constant (see table)

  G Value of the measured current

  Gs Value of the programmed threshold (pick-up value)

  15.2 Thermal Overload Curves

  The thermal time characteristic is given by:

  =

  Where:

  t = Tripping time, following application of the overload
  current, I

  = Heating and cooling time constant of the protected plant

  I = Highest phase current

  Itherm = Setting value of thermal model. It is the full load
  current rating (IFLC) multiplied by a safety factor (for example
  1.05, which allows continuous operation up to < 1.05 IFLC)

  IP = Steady state pre-loading current before application of the
  overload

  The tripping time varies depending on the load current carried
  before application of the overload, i.e. whether the overload was
  applied from «hot» or «cold».

  The thermal overload time characteristic curves are given in the
  Technical Data chapter.

  If the current in any phase is above 0.1 x Itherm setting value
  the mathematical formula is following:

  =

  ript

  p

  K

  Where:

  t Trip = Tripping time (in seconds)

  Te = Thermal time constant of the protected plant (in
  seconds)

  K = Thermal overload equal to therm

  eq

  II

  Ieq = Equivalent current corresponding to the RMS value of the
  highest phase current

  IP = Steady state pre-loading current before application of the
  overload

  Itherm = Setting value. It is the full load current rating
  increased by a safety factor k (for example if k = 1.05 then Itherm
  = k*IFLC =1.05*IFLC) given by the national standard or by the
  supplier

  P = Steady state pre-loading thermal state before application of
  the overload

  alarm = Initial thermal state. If the initial thermal state =
  30% then =0.3

  trip = Trip thermal state. If the trip thermal state is set at
  100%, then trip = 1

  The settings of these parameters are available in the various
  menus. The calculation of the thermal state is given by the
  following formula:

  If all the phase currents are above 0.1 x Itherm the value of Tr
  (time constant for cooling) is used instead of Te (time constant
  for heating).

  In a typical application (transformer, cable, …) Tr should be
  equal to Te. Different setting values
