The engineering manual contains instructions on how to engineer the IEDs using the

various tools available within the PCM600 software. The manual provides

instructions on how to set up a PCM600 project and insert IEDs to the project

structure. The manual also recommends a sequence for the engineering of protection

and control functions, LHMI functions as well as communication engineering for IEC

60870-5-103, IEC 61850 and DNP3.

The installation manual contains instructions on how to install the IED. The manual

provides procedures for mechanical and electrical installation. The chapters are

organized in the chronological order in which the IED should be installed.

The commissioning manual contains instructions on how to commission the IED. The

manual can also be used by system engineers and maintenance personnel for

assistance during the testing phase. The manual provides procedures for the checking

of external circuitry and energizing the IED, parameter setting and configuration as
well as verifying settings by secondary injection. The manual describes the process of

testing an IED in a substation which is not in service. The chapters are organized in the

chronological order in which the IED should be commissioned. The relevant

procedures may be followed also during the service and maintenance activities.

The operation manual contains instructions on how to operate the IED once it has been

commissioned. The manual provides instructions for the monitoring, controlling and

setting of the IED. The manual also describes how to identify disturbances and how to

view calculated and measured power grid data to determine the cause of a fault.

The application manual contains application descriptions and setting guidelines

sorted per function. The manual can be used to find out when and for what purpose a

typical protection function can be used. The manual can also provide assistance for

calculating settings.

The technical manual contains application and functionality descriptions and lists

function blocks, logic diagrams, input and output signals, setting parameters and

technical data, sorted per function. The manual can be used as a technical reference

during the engineering phase, installation and commissioning phase, and during

normal service.

The communication protocol manual describes the communication protocols

supported by the IED. The manual concentrates on the vendor-specific

implementations.

The point list manual describes the outlook and properties of the data points specific

to the IED. The manual should be used in conjunction with the corresponding

communication protocol manual.

The cyber security deployment guideline describes the process for handling cyber

security when communicating with the IED. Certification, Authorization with role

based access control, and product engineering for cyber security related events are

described and sorted by function. The guideline can be used as a technical reference

during the engineering phase, installation and commissioning phase, and during

normal service.

The caution icon indicates important information or warning related

to the concept discussed in the text. It might indicate the presence of

a hazard which could result in corruption of software or damage to

equipment or property.

The information icon alerts the reader of important facts and

conditions.

The tip icon indicates advice on, for example, how to design your

project or how to use a certain function.

Although warning hazards are related to personal injury, it is necessary to understand

that under certain operational conditions, operation of damaged equipment may result

in degraded process performance leading to personal injury or death. It is important

that the user fully complies with all warning and cautionary notices.

1.4.2 Document conventions

• Abbreviations and acronyms in this manual are spelled out in the glossary. The

glossary also contains definitions of important terms.

• Push button navigation in the LHMI menu structure is presented by using the

push button icons.

For example, to navigate between the options, use and .

• HMI menu paths are presented in bold.

For example, select Main menu/Settings.

• LHMI messages are shown in Courier font.

For example, to save the changes in non-volatile memory, select Yes and press

.

• Parameter names are shown in italics.

For example, the function can be enabled and disabled with the Operation setting.

• Each function block symbol shows the available input/output signal.

• the character ^ in front of an input/output signal name indicates that the

signal name may be customized using the PCM600 software.

• the character * after an input signal name indicates that the signal must be

connected to another function block in the application configuration to

achieve a valid application configuration.

• Logic diagrams describe the signal logic inside the function block and are

bordered by dashed lines.

Symbols on the product

All warnings must be observed.

Read the entire manual before doing installation or any maintenance

work on the product. All warnings must be observed.

Class 1 Laser product. Take adequate measures to protect your eyes

and do not view directly with optical instruments.

Do not touch the unit in operation. The installation shall take into

account the worst case temperature.

2.2 Warnings

Observe the warnings during all types of work related to the product.

Only electrically skilled persons with the proper authorization and

knowledge of any safety hazards are allowed to carry out the electrical

installation.

National and local electrical safety regulations must always be

followed. Working in a high voltage environment requires serious

approach to avoid human injuries and damage to equipment.

Do not touch circuitry during operation. Potentially lethal voltages

and currents are present.

Always use suitable isolated test pins when measuring signals in open

circuitry. Potentially lethal voltages and currents are present.

Never connect or disconnect a wire and/or a connector to or from a

IED during normal operation. Hazardous voltages and currents are

present that may be lethal. Operation may be disrupted and IED and

measuring circuitry may be damaged.

Dangerous voltages can occur on the connectors, even though the

auxiliary voltage has been disconnected.

Always connect the IED to protective earth, regardless of the

operating conditions. This also applies to special occasions such as

bench testing, demonstrations and off-site configuration. This is class

1 equipment that shall be earthed.

Never disconnect the secondary connection of current transformer

circuit without short-circuiting the transformer’s secondary winding.

Operating a current transformer with the secondary winding open will

cause a massive potential build-up that may damage the transformer

and may cause injuries to humans.

Never remove any screw from a powered IED or from a IED

connected to powered circuitry. Potentially lethal voltages and

currents are present.

Take adequate measures to protect the eyes. Never look into the laser

beam.

The IED with accessories should be mounted in a cubicle in a

restricted access area within a power station, substation or industrial

or retail environment.

Whenever changes are made in the IED, measures should be taken to

avoid inadvertent tripping.

The IED contains components which are sensitive to electrostatic

discharge. ESD precautions shall always be observed prior to

touching components.

Always transport PCBs (modules) using certified conductive bags.

Do not connect live wires to the IED. Internal circuitry may be

damaged

Always use a conductive wrist strap connected to protective earth

when replacing modules. Electrostatic discharge (ESD) may damage

the module and IED circuitry.

Take care to avoid electrical shock during installation and

commissioning.

Changing the active setting group will inevitably change the IEDs

operation. Be careful and check regulations before making the

change.
