The intended use of manuals in different lifecycles

The engineering manual contains instructions on how to engineer the protective relay 
using the different tools in PCM600. The manual provides instructions on how to set up a 
PCM600 project and insert protective relays in the project structure. The manual also 
recommends a sequence for engineering of protection and control functions, LHMI 
functions, and communication engineering for IEC 61850 and DNP3.

The installation manual contains instructions on how to install the protective relay. The 
manual provides procedures for mechanical and electrical installation. The chapters are 
organized in chronological order in which the protective relay should be installed.

The operation manual contains instructions on how to operate the protective relay once it 
has been commissioned. The manual provides instructions for monitoring, controlling and 
setting the protective relay. 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. 

The application manual contains application descriptions and setting guidelines sorted per 
function. The manual can be used to find out when and for what purpose a typical 
protection function can be used. The manual can also be used when calculating settings.

The technical manual contains application and functionality descriptions and lists function 
blocks, logic diagrams, input and output signals, setting parameters and technical data
