E.2 Functional Earth (FE) Requirements
In order to ensure proper EMC behavior, the module must be properly connected to functional
earth via the FE pad/FE mechanism described in the Anybus CompactCom 40 Hardware
Design Guide. Proper EMC behavior is not guaranteed unless these FE requirements are
fulfilled.
The shield of the RJ45 connector is not connected directly to FE. As all nodes in a PROFINET
network have to share chassis ground connection, the PROFINET cable shield has to be con-
nected to the chassis ground at each node in the network.

able for download at www.profinet.com.
E.3 Power Supply
E.3.1 Supply Voltage
The Anybus CompactCom 40 PROFINET IRT requires a regulated 3.3 V power source as
specified in the general Anybus CompactCom 40 Hardware Design Guide.
