Connection to Functional Earth Ground
Snapping the switch onto a grounded DIN rail connects it to
the ground potential. In an environment particularly prone
to EMI, the switch can be grounded by an additional low-im-
pedance connection to functional earth ground via an eye-
let ring on the upper part of the housing.

Ethernet Interface
The FL SWITCH SFN ... has up to 8 Ethernet ports on the front in RJ45 format, to which only twisted pair cables with an
impedance of 100 Ω can be connected. The data transmission speed is 10 Mbps/100 Mbps or
10 Mbps/100 Mbps/1000 Mbps. In addition, every port has an auto crossing function: it is not necessary to make a distinc-
tion between 1:1 or crossover Ethernet cables.
