Section 1 Introduction
1.1 This manual
GUID-AB423A30-13C2-46AF-B7FE-A73BB425EB5F v19
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.
1.2 Intended audience
GUID-C9B8127F-5748-4BEA-9E4F-CC762FE28A3A v11
This manual addresses the personnel responsible for commissioning, maintenance and taking
the IED in and out of normal service.
The commissioning personnel must have a basic knowledge of handling electronic equipment.
The commissioning and maintenance personnel must be well experienced in using protection
equipment, test equipment, protection functions and the configured functional logics in the
IED.

Figure 1: The intended use of manuals throughout the product lifecycle
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, as well as communication
engineering for IEC 61850.
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.
