Section 4 Starting up4.1 Factory and site acceptance testing GUID-38C2B5FA-9210-4D85-BA21-39CE98A1A84A v2Testing the proper IED operation is carried out at different occasions, for example:• Acceptance testing• Commissioning testing• Maintenance testingThis manual describes the workflow and the steps to carry out the commissioningtesting.Factory acceptance testing (FAT) is typically done to verify that the IED and itscorresponding configuration meet the requirements of the utility or industry. Thistest is the most complex and in depth, as it is done to familiarize the user with anew product or to verify a new configuration. The complexity of this testingdepends on several factors, such as:• New IED type• New configuration• Modified configurationSite acceptance testing (SAT or commissioning testing) is typically done to verifythat the installed IED is correctly set and connected to the power system. SATrequires that the acceptance testing has been performed and that the applicationconfiguration is verified.Maintenance testing is a periodic verification that the IED is healthy and hascorrect settings, depending on changes in the power system. There are also othertypes of maintenance testing.4.2 Commissioning checklist GUID-93D14E4E-5DDE-4D37-84A6-2DF0656AB73D v3Before starting up commissioning at site, check that the following items areavailable.• Single line diagram• Protection block diagram• Circuit diagram• Setting list and configuration• RJ-45 Ethernet cable (CAT 5)1MRK 511 425-UEN A Section 4Starting upBay control REC650 2.2 IEC 29Commissioning manual
