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, LHMI functions as well as communication
engineering for IEC 60870-5-103, IEC 61850, DNP3, LON and SPA.
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
