Please ensure the correct setting of the current transformer, check the performance
values of the individual phases - these must not possess any negative signs when
drawing energy. Also check the power factor for plausibility. Turn the current
transformer if necessary!
Up to 2 residual current
measurements can be selected!

Attention! Fatal hazard due to electrical energy:
High voltage spikes that are dangerous to touch can occur on current transformers
that are driven with open-circuit secondary windings! For this reason, never operate
current transformers with open-circuit secondary windings!
First connect the current transformer lines to the corresponding measurement case
inputs!
