CONNECTION DIAGRAM

Note: In loop mode, wires from BP1 must end at AP1; wires from BS1 must end at AS1. The connection of field
devices (except FDCL181 isolator) is polarity free.

Note: Ensure positive and negative connections are properly in place; FC18-BUS is polarity sensitive.
Connect a 120Ω resistor as monitoring resistor. It must be connected to the end of the line. ( It can be set by
the two-digit Dip-switch on the main board, see "Dip-switch connection configuration" )
