during the testing phase. The manual provides procedures for the checking of externalcircuitry and energizing the IED, parameter setting and configuration as well as verifyingsettings by secondary injection. The manual describes the process of testing an IED in asubstation which is not in service. The chapters are organized in the chronological orderin which the IED should be commissioned. The relevant procedures may be followed alsoduring the service and maintenance activities.The operation manual contains instructions on how to operate the IED once it has beencommissioned. The manual provides instructions for the monitoring, controlling andsetting of the IED. The manual also describes how to identify disturbances and how toview calculated and measured power grid data to determine the cause of a fault.The application manual contains application descriptions and setting guidelines sorted perfunction. The manual can be used to find out when and for what purpose a typicalprotection function can be used. The manual can also provides assistance for calculatingsettings.The technical manual contains application and functionality descriptions and listsfunction blocks, logic diagrams, input and output signals, setting parameters and technicaldata, sorted per function. The manual can be used as a technical reference during theengineering phase, installation and commissioning phase, and during normal service.The communication protocol manual describes the communication protocols supportedby 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 theIED. The manual should be used in conjunction with the corresponding communicationprotocol manual.1.3.2 Document revision historyDocument revision/date History-/March 2013 First releaseA/October 2016 Minor corrections made1.3.3 Related documentsDocuments related to REL650 Identity numberApplication manual 1MRK 506 334-UUSTechnical manual 1MRK 506 335-UUSCommissioning manual 1MRK 506 336-UUSProduct Guide 1MRK 506 337-BUSType test certificate 1MRK 506 337-TUSApplication notes for Circuit Breaker Control 1MRG0068061MRK 506 334-UUS A Section 1Introduction21Application manual
