The Functional Earth (FE) connection of the device has to be connected at low
inductance with the protective earth (PE) of the system.
As indicated in the connection diagram, the power can be applied alternatively by a
special DIN rail connector (Rail Power Supply). For further information contact ABB.
2.4.4 Ethernet Ports
The Linking Device is equipped with two 10/100 Base-T Ethernet interface receptacles
(RJ45). Ethernet port 1 (ETH 1) is intended to be connected to a Foundation High Speed
Ethernet system (HSE). Do not use Ethernet port 2 (ETH 2). It is reserved for future use.
The Ethernet port corresponds to the IEEE 802.3 with the pin assignment shown in the
following table.
