The connection for 100 V AC ... 240 V AC is established using the L, N, and P screw connections.
The device can be connected to 1-phase AC networks or to two of the phase conductors of three-phase systems (TN, TT or
IT systems in accordance with VDE 0100-300/IEC 60364-3) with nominal voltages of 100 V AC ... 240 V AC.
The device also continues to work on short-term input voltages > 300 V AC.
For operation on two of the phase conductors of a three-phase system, an isolating facility for all poles must
be provided.
