The exact I/O-configuration for circuits A, B, C and D is order-specific and can be determined by
the CG35 number shown on the I/O sticker inside the terminal compartment. Therefore check
the data on the back of the UFC 400 electronics unit. The CG35 number contains 10 characters
of which the last three characters (XYZ) determine the configuration of the I/O circuits:

For schematic overviews of the CG35 numbers, refer to

Non-I.S. I/O connections

on page 21 and

refer to

I.S. I/O connections

on page 23. These overviews do not show all details. The exact

connection diagram of a specific UFC 400 signal converter can be found on the sticker inside the
terminal compartment.
