This document serves as the commissioning manual for the Relion® 670 SERIES Busbar protection REB670, Version 2.2 IEC. It provides instructions for commissioning the IED (Intelligent Electronic Device), and can also be used by system engineers and maintenance personnel for testing. The manual covers procedures for checking external circuitry, energizing the IED, parameter setting and configuration, and verifying settings via secondary injection. It outlines the process of testing an IED in a substation not yet in service, with chapters organized chronologically according to the commissioning sequence. Relevant procedures can also be followed during service and maintenance activities.
