2.4 Planning for Installation and Programming, Required Field Documentation
The
OPTI
mizer

application should be planned, much like the application of other IEDs, such as a protective relay, fault
recorder, or monitor. Actual programming and installation can be accomplished in a few hours (typically 2 hours) after the
setpoints are calculated and determined. The required information is tabulated below:
