Block circuits
Block circuits may be connected to equipment located in a different switchboard: For the aim of
reliability, it is recommended to use conductors having a cross sectional thickness of at least 1 mm
2
and to not exceed 5 km in length. For connections that are particularly critical in terms of electro-
magnetic pollution, it is recommended to use BFO adaptor modules with fi bre optic connection.
When devices without committed pilot wire circuits must be embedded (devices other than Pro-N
or Pro-NX), or in the event that further I/O circuits are need, output relays and binary inputs can be
customized to work in the logic selectivity system together with the committed pilot wire circuits.
