Ethernet connection X3 and X4 (optional)
WARNING!
Danger from compensation currents on shielding!
Compensation currents flowing through shielding in extended systems can
lead to damage to the interfaces and hazards when working on the data
lines.
Any measures (such as connecting to a shared distribution board, expand-
ing a TN-S network, etc.) should be discussed with the person responsible
for building services.
Information
The Ethernet1 connector X4 (LSA+
®
) and the Ethernet2 connector X3
(RJ45) are connected in parallel on the PCB and can not be used at the
same time. The unused connection must be disconnected if necessary (e.g.
during servicing).
The Ethernet1 connection X4 is designed as terminal block in LSA+
®
tech-
nology. A hard-wired communication (e.g. for SmartHome or a charging net-
work) may only be carried out on this LSA+
®
connection.
The Ethernet2 connector X3 (RJ45) is for device diagnosis purposes only
(debugging).
