WARNING
circuit, 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 unsure
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 Connect
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. 7: Network configuration, single phase 120 V two-wire
grid variant with earthed N-line and Imax = 80 A
Split phase 240 V
Connection of the Wall Charger Connect between L1
and L2.
The maximum charging power here is 19.2 kW.

180°, network frequency 60 Hz)
Wye 208 V
Configuration for connecting the Wall Charger
Connect:
L1 – L2
L1 – L3
L2 – L3
Ensure that the two phases used have a maximum
voltage of 120 V to ground.
Installation Instructions

120° each, network frequency 60 Hz)
Delta network (Delta High Leg)
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
L1 – N
L2 – N
Fig. 10: Network configuration Delta High Leg (example)
Information
In this configuration, the Wall Charger Connect may
neither be connected to L1 – L3 nor L2 – L3.
