WARNING: a 4-wire three-phase distribution system is required.
The standard version of the UPS should be connected to a power supply line made up of 3 n
PE (protective earth) of the TT, TN or IT type (in accordance with the IEC 60364-3 standard); the phase
rotation must therefore be respected.
There are (optional) TRANSFORMER BOXES to convert the distribution systems from 3 wires to 4 four wires.
