Pin Assignments Of The Swt 3000 Modules; Pin Assignment Of The Ifc-X Module - Siemens SWT-3000 Equipment Manual

Installation and Commissioning

Pin assignments of the SWT 3000 modules:

Pin assignment of the IFC-x module

The IFC interface modules must be connected from the protective relay to connector X1 (modular
terminal block) (cable cross section up to 1.5 mm
ately at the terminals.
IFC-D Interface module for direct tripping
IFC-P Interface module for permissive tripping
IFC-S Interface module for signaling
