WARNING: a 4-wire three-phase distribution system is required.
The UPS must be connected to a power supply line made up of 3 phases + neutral + PE (protective earth) of TT, TN
or IT type. Therefore, the phase rotation must be respected.
Optional TRANSFORMER BOXES to convert the distribution systems from 3 wires to 4 wires are available.
