ELECTRICAL CONNECTIONS
WARNING: a 4-wire three-phase distribution system is required for the three-phase input connection.
The CPS 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.
WIRING DIAGRAMS FOR CONNECTING TO THE ELECTRICAL SYSTEM
NOTE: for the following diagrams, in cases of single-phase connections on the input line, instead of 3P=N, please read
P+N.
CPS without any variation in neutral condition and with separate bypass input
CPS with galvanic isolation and with separate bypass input
CPS with galvanic isolation at output and separate bypass input
