Outputs for signalling

Signal output contacts are used for signalling on starting and tripping of the IED. On delivery from

the factory, the pickup and alarm signals from all the protection stages are routed to signalling

outputs. See connection diagrams.

Each signal connector terminal is connected with one 14 or 16 Gauge wire.
