WARNING
cuit, fire
Improper connection in a non-compatible network
configuration can cause short circuits, electric
shocks, explosions, fires or burns.
e
The Wall Charger Connect is a 1-phase device.
Therefore you should not connect to a three-
phase source.
e
Before the Wall Charger Connect is connected,
check which network configuration is available
on site. The Wall Charger Connect may only be
used with the network configurations listed here
in the corresponding arrangement. If you are un-
sure about the network configuration, consult a
qualified electrician.
e
The two phases used may only have a maximum
voltage of 120 V to neutral. Neutral may only be
connected to ground at one place, normally in
the fuse box.
e
In total, only three cables are connected to the
Wall Charger Connect. Ensure that the cables in
your distribution box are correctly connected and
labelled.
e
Always ensure that neutral is connected to
ground in the installation. Only in this way is
the reliable operation of the Wall Charger Con-
nect guaranteed. If no ground is available in the
installation, a grounding stake must be installed.
The Wall Charger Connect can be integrated in the
following network configurations:
Single phase 120 V
Connection of the Wall Charger Connect between L1
and N.
The maximum power of this configuration is 9.6 kW.
Fig. 5 Network configuration, single phase 120 V
two-wire grid variant with grounded N-line and Imax
= 80 A
At Imax = 40 A, the maximum power is 4.8 kW.
Split phase 120 V/240 V
Connection of the Wall Charger Connect between L1
and L2.
The maximum charging power here is 19.2 kW.

(phase angle 180°, network frequency 60 Hz)
Requirements and prerequisites
Wye 208 V
Configuration for connecting the Wall Charger Con-
nect:
–
L1 – L2 + N/GND
–
L1 – L3 + N/GND
–
L2 – L3 + N/GND
e
Ensure that the two phases used have a maxi-
mum voltage of 120 V to ground.
Fig. 7 Network configuration, split wye 208 V (phase
angle 120° each, network frequency 60 Hz)
Split phase delta/high leg delta 240 V.
For delta connections, one strand must have a center
tap. Only the two phases adjacent to the center tap
may be used.
The two phases used must each measure 120 V to
the neutral wire.
In the following example only these configurations
are permitted:
– L1 – L2 + N/GND
