Connection
When connecting external meters please note the following:
•
The connection is made via the Ethernet1 connection X4 (LSA+®). For this, the meter must be in
the same network as the charging station.
•
The meter must be connected with the same phase sequence as the charging station, so that the
house load calculation and the charging optimization are carried out correctly. If it is necessary to
connect the charging station beginning with phase 2 in order to better distribute the phase loads,
the meter must also be connected beginning with phase 2.

Settings
The Modbus TCP feature is disabled by default. If an external meter with a Modbus TCP network
interface was installed in the system, it must be configured in the web interface in advance.
Setting the current of the post-meter fuse
The post-meter fuse is designed for a certain current level. In order to calculate the charging current, the
current of the post-meter fuse must be set via the DIP switches in the connection panel of the charging
station. If no external meter is found when the Modbus TCP function is activated, the charging current is
reduced to 10 A.
The setting must be made on the DIP switch DSW1. The following DIP switches can only set a maximum
value that is less than or equal to the current of the post-meter fuse.
