Section 1 Introduction
1.1 This manual GUID-AB423A30-13C2-46AF-B7FE-A73BB425EB5F v20
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.
