    Operator’s Manual Technical Description REJ 527 is designed to be used as a stand-alone protection relay in medium voltage distribution systems where the relay can be applied as the main or backup protection relay of an object. The whole function software used in the relay is preloaded into program memory in production stage.

  • Page 26: Service

    Please contact the manufacturer or the nearest representative for further information about checking, overhaul and recalibration of the relay. When contacting ABB for ordering service, please state the possible fault code. Note! Static protection relays are measuring instruments that should be handled with care and protected against moisture and mechanical stress, especially during transport.
