1. SAFETY & HANDLING
1.1 Introduction
The present document describes the safety, handling, packing and unpacking procedures
applicable to MiCOM H16x Ethernet Switch Range and associated equipments.
1.2 Safety
WARNING: This safety section should be read before commencing any work on the
equipment.
1.2.1 Health and Safety
The information in the Safety Section of the product documentation is intended to ensure
that products are properly installed and handled in order to maintain them in a safe condition.
It is assumed that everyone who will be associated with the equipment will be familiar with
the contents of the Safety Section.
1.2.2 Explanation of symbols and labels
The meaning of symbols and labels may be used on the equipment or in the product
documentation, is given below.
NOTE: The term earth used throughout the product documentation is the
direct equivalent of the North American term ground.
1.2.3 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 product
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.
If there is unlocked access to the rear of the equipment, care should be taken by all
personnel to avoid electrical 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.
Before energising the equipment it must be earthen using the protective earth terminal, or
the appropriate termination of the supply plug in the case of plug connected equipment.
Omitting or disconnecting the equipment earth may cause a safety hazard.
The recommended minimum earth wire size is 2.5mm², unless otherwise stated in the
technical data section of the product documentation.
Before energising the equipment, the following should be checked:
• Voltage rating and polarity;
• CT circuit rating and integrity of connections;
• Protective fuse rating;
• Integrity of earth connection (where applicable)

H16x/EN GL/A11 Global Documentation
Page 4/26 MiCOM H16x
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 level voltage produced may be
lethal to personnel and could damage insulation.
External resistors
Where external resistors are fitted to MiCOM product, these may present a risk of electric
shock or burns, if touched.
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 boards
These must not be inserted into or withdrawn from equipment whist it is energised since this
may result in damage.
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.
1.2.4 Decommissioning and Disposal
Decommissioning:
The auxiliary supply circuit in the MiCOM H16x may include capacitors across the supply or
to earth. To avoid electric shock or energy hazards, after completely isolating the supplies to
the MiCOM H16x (both poles of any dc supply), the capacitors should be safely discharged
via the external terminals prior to decommissioning.
Disposal:
It is recommended to avoid incineration and disposal to. The product should be disposed of
in a safe manner. Any products containing batteries should have them removed before
disposal, in order to avoid short circuits. Particular regulations within the country of operation
may apply to the disposal of lithium batteries.

1.4 Handling of electronic equipments
A person’s normal movements can easily generate electrostatic potentials of several
thousand volts.
Discharge of these voltages into semiconductor devices when handling circuits can cause
serious damage, which often may not be immediately apparent but the reliability of the circuit
will have been reduced.
The electronic circuits of T&D Automation products are immune to the relevant levels of
electrostatic discharge when housed in their cases. Do not expose them to the risk of
damage by withdrawing modules unnecessarily.
Each module incorporates the highest practicable protection for its semiconductor devices.
However, if it becomes necessary to withdraw a module, the following precautions should be
taken in order to preserve the high reliability and long life for which the equipment has been
designed and manufactured.
Before removing a module, ensure that you are a same electrostatic potential as the
equipment by touching the case.

H16x/EN GL/A11 Global Documentation
Page 6/26 MiCOM H16x
Handle the module by its front-plate, frame, or edges of the printed circuit board. Avoid
touching the electronic components, printed circuit track or connectors.
Do not pass the module to any person without first ensuring that you are both at the same
electrostatic potential. Shaking hands achieves equipotential.
Place the module on an antistatic surface, or on a conducting surface, which is at the same
potential as you.
Store or transport the module in a conductive bag.
More information on safe working procedures for all electronic equipment can be found in
IEC 60147-0F and BS5783.
If you are making measurements on the internal electronic circuitry of any equipment in
service, it is preferable that you are earthen to the case with a conductive wrist strap.
Wrist straps should have a resistance to ground between 500k – 10M Ohms. If a wrist strap
is not available you should maintain regular contact with the case to prevent the build up of
static. Instrumentation which may be used for making measurements should be earthen to
the case whenever possible.
T&D AUTOMATION strongly recommends that detailed investigations on the electronic
circuitry, or modification work, should be carried out in a Special Handling Area such as
described in IEC 60147-0F or BS5783.
1.5 Packing and unpacking
All MiCOM H16x Ethernet Switchs are packaged separately in their own cartons and shipped
inside outer packaging. Use special care when opening the cartons and unpacking the
device, and do not use force. In addition, make sure to remove from the inside carton the
supporting documents supplied with each individual device and the type identification label.
The design revision level of each module included with the device in its as-delivered
condition can be determined from the list of components. This list should be carefully saved.
After unpacking the device, inspect it visually to make sure it is in proper mechanical
condition.
If the MiCOM H16x Ethernet switch needs to be shipped, both inner and outer packaging
must be used. If the original packaging is no longer available, make sure that packaging
conforms to ISO 2248 specifications for a drop height ≤0.8m.

1.8 Warnings regarding use of T&D Automation products
T&D AUTOMATION products are not designed with components and testing for a level of
reliability suitable for use in or in connection with surgical implants or as critical components
in any life support systems whose failure to perform can reasonably be expected to cause
significant injuries to a human.
In any application, including the above reliability of operation of the software products can be
impaired by adverse factors, including -but not limited- to fluctuations in electrical power
supply, computer hardware malfunctions, computer operating system, software fitness,
fitness of compilers and development software used to develop an application, installation
errors, software and hardware compatibility problems, malfunctions or failures of electronic
monitoring or control devices, transient failures of electronic systems (hardware and/or
software), unanticipated uses or misuses, or errors from the user or applications designer
(adverse factors such as these are collectively termed "System failures").
Any application where a system failure would create a risk of harm to property or persons
(including the risk of bodily injuries and death) should not be reliant solely upon one form of
electronic system due to the risk of system failure to avoid damage, injury or death, the user
or application designer must take reasonably steps to protect against system failure,
including -but not limited- to back-up or shut-down mechanisms, not because end-user
system is customised and differs from T&D AUTOMATION’ testing platforms but also a user
or application designer may use T&D AUTOMATION products in combination with other
products. These actions cannot be evaluated or contemplated by T&D AUTOMATION,;
Thus, the user or application designer is ultimately responsible for verifying and validating
the suitability of T&D AUTOMATION products whenever they are incorporated in a system or
application, even without limitation of the appropriate design, process and safety levels of
such system or application.
