7. Home setup: Setting mains phases
Set the number of available mains phases for the
house connection.
Option Explanation
Single phase Only one phase is used.
Split phases Single-phase three-wire network
Three-phase Three phases are used.
8. Home setup: Assign current converter
The possible connection positions of the current con-
verters are listed here in tabular form.
The Connection position on the device (CTx, where
x=1-12) must be set individually for each current
converter.
The connection positions for which the current trans-
former cables were connected to the device must be
activated and configured (numbering on the device
from right to left 1–12). In addition, it is necessary
to define which phase is measured with the current
converter.
Information
A maximum of twelve current transformers can be
connected and configured. This makes it possible to
monitor the main lines and lines to the sub-distribu-
tion systems and a solar system.
b The connection positions of all connected cur-
rent transformers were checked on the device.
1. Activate the current converters used for moni-
toring in the table.
2. Enter the corresponding settings for each cur-
rent converter:

Phase Specification of the

ured by the cur-
rent converter at the
specified connection
position (CTx).
Current sensor Designation of the
installed current con-
verter.

Column Explanation
If in doubt, check the
identification of the
installed current con-
verter.
Current limit [A] Specification of the
current limit of the
line fuse to which the
current converter is
connected.
The value must not
exceed the rated cur-
rent of the fuse of
the line to which the
current converter is
connected. A 2 A
lower value is recom-
mended. The default
setting is therefore
30 A for 32 A fuses.
Live analysis* Visibility in live analy-
sis
* For live analysis
The live analysis is used by the electrician to
check whether the phase is configured correctly and
whether the current transformer was installed cor-
rectly. The live analysis shows current values with
direction (+/-) from a measured current of 3 A and
also gives an estimate of the phase at which the
current converter is located. In relation to the current
direction, there is a consumption at negative values,
and at positive values there is a supply at the meas-
uring point. The measured current of a solar system
must be negative.
