group13Name is a read-write text field (up to 64 characters) that lets an admin assign a human-readable label to logical receptacle group 13, one of up to 16 groups the Unity PDU can organize its outlets into. Naming the group matters because group 13's outlets are tracked and reported together, so a clear name helps an admin recognize what that aggregated set of receptacles represents when reviewing grouped status or alarms. For example, an admin might set group13Name to describe a storage shelf's power inputs, so group 13 is immediately identifiable in the PDU's group listing rather than just showing as 'Group 13'.
