Pxxxx/EN SS/C11
Safety Section Page 5/10
4. INSTALLING, COMMISSIONING AND SERVICING
Equipment connections
Personnel undertaking installation, commissioning or servicing work for 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.
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 energising the equipment it must be earthed using the protective conductor
terminal, if provided, or the appropriate termination of the 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.
The recommended minimum protective conductor (earth) wire size is 2.5 mm²
(3.3 mm² 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 energising 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.

Pxxxx/EN SS/C11
Page 6/10 Safety Section
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/fuseholders 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.
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 energised, 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 energised. This
is to avoid possible shock or damage hazards. Hazardous live voltages may be
accessible on the extender card.
Insertion and withdrawal of integral heavy current test plugs
It is possible to use an integral heavy current test plug with some equipment.
CT shorting links must be in place before insertion or removal of heavy current
test plugs, to avoid potentially lethal voltages.

Pxxxx/EN SS/C11
Safety Section Page 7/10
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.
Fibre optic communication
Where fibre 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 energised. Contact fingers of test plugs are normally
protected by petroleum jelly which should not be removed.
5. DECOMMISSIONING AND DISPOSAL
Decommissioning:
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
decommissioning.
Disposal:
It is recommended that incineration and disposal to water courses is avoided.
The equipment should be disposed of in a safe manner. Any equipment
containing batteries should have them removed before disposal, taking
precautions to avoid short circuits. Particular regulations within the country of
operation, may apply to the disposal of batteries.
6. EQUIPMENT WHICH INCLUDES ELECTROMECHANICAL ELEMENTS
Electrical adjustments
It is possible to change current or voltage settings on some equipment by direct
physical adjustment e.g. adjustment of a plug-bridge setting. The electrical power
should be removed before making any change, to avoid the risk of electric shock.
Exposure of live parts
Removal of the cover may expose hazardous live parts such as relay contacts,
these should not be touched before removing the electrical power.
