5.1.6 Tips and Tricks

lowest possible need of changes. For the majority
of applications, the Quick Menu, Quick Set-up
provides the simplest and quickest access to all
the typical parameters required.
•
Performing an Auto CT for all stand-alone filters
to set correct current sensor set-up. Auto CT set-
up is only possible if CTs are installed at Point of
Common Coupling PCC (towards the transformer).
CT of LHD is preset from factory.
