Infeed terminal in the Basic Line Connection Module or Active Line Connection Module
The terminal in the Basic Line Connection Module or the Active Line Connection Module
comprises the X100 terminal block for feeding in the auxiliary voltages. No voltage taps are
available to the customer. When option K76 is available (auxiliary power generation in the
Line Connection Module), then terminal X100 is already assigned in the factory.
