The IED offers six different settings groups which can be set based on individual
needs. Each group can be activated or deactivated using the setting group settings
available in the IED.
Depending on the communication protocol the required function block needs to be
instantiated in the configuration.

Functional diagrams for protection

The functional diagrams describe the IED's protection functionality in detail and
according to the factory set default connections.
Four overcurrent stages are offered for overcurrent and short-circuit protection. Three
of them include directional functionality DPHxPDOC.
