ATTENTION!
Possible destruction of the EV charging box
Incorrect installation may cause the destruction of the EV charging box.
► The connection terminals of the neutral conductor must always be connected in all network systems.
► Observe the Assembly and installation instructions.

230 V
PE N L1
Each of the three phases, L1, L2, L3 must be
connected to L1, L2, L3 of the PCB terminal block
of the EV charging box. The neutralconductor is
connected to N of the PCB terminal block. Each
phase voltage must be within a range of 207 to
253 V rated voltage to the neutral conductor.
230 V 1-phase with neutral conductor
PE N L1
IN
230 V
PE N L1
Any phase must be connected to L1 of the PCB
terminal block of the EV charging box. The
neutral conductor must be connected to N. The
phase voltage between the conductor and neutral
conductor must be in a range of 207 to 253 V
rated voltage.

Without a neutral conductor, any three phases
must be connected to L1, L2 and N of the PCB
terminal block of the EV charging box. The phase
voltage between the cables must be in a range of
207 to 253 V rated voltage.
230 V 1-phase without neutral conductor
L2 L3
Without a neutral conductor, any two phases must
be connected to L1 and N of the PCB terminal
block of the EV charging box. The phase voltage
between the cables must be in a range of 207 to
253 V rated voltage.
