1 Introduction
These instructions are supplementary to the “Installation and Operating Instructions IFC 090 K / F“. The details
depicted therein, in particular the Safety Information are valid and should be adhered to. The present
Supplementary Instructions provide additional information for the devices when being operated and connected
to a Foundation Fieldbus.
Note: Please set the controller to manual mode before changing parameters of the IFC 090.
The present Supplementary Instruction for the IFC 090 with Foundation Fieldbus- interface, plus a diskette with
the DD and CCF file are included in our scope of supply, in addition to those items delivered for the standard
device.

2.2 Electrical Connection of Foundation Fieldbus Devices
Connect the bus cable as shown in the figure.
• Connect the cable cores to terminals D and DI.. Polarity reversal will not have any effect.
• The cable shield should be connected with minimum length to the FE functional ground.
• The equipotential bonding conductor must be connected to the device by connecting it to FE functional
ground.
