This manual contains application and functionality descriptions and connection

diagrams, input and output signals, setting parameters and technical data. The

manual can be used as a technical reference during the engineering phase,

installation and commissioning phase, and during normal service. The manual

can also be used when calculating settings. Instructions on how to operate the IED

during normal service once it has been commissioned and it can be used to fi nd

out how to handle disturbances or how to view calculated and measured network

data in order to determine the cause of a fault

Intended Audience
