5.6 Networking devices

For Professional+ (PnC) 22 (T2S) versions only.
In "Networked" operating mode only.
Fig. 17: Ethernet connection
The devices have to be connected to a central router or
switch via the ethernet cable in order to connect several
devices to form a network. The wiring must be carried out
in star topology.
f Connect the central router or switch and the ethernet
surge protector (1) via an ethernet cable (2).
f Also connect the other devices to the router or switch.
Whenever an external energy meter is to be
integrated in the network for the purpose of load
management, then the device also has to be
connected to the router or switch via an ethernet
cable.
