Installation Notes
- Verify the exact variant (-ABR01/-ABR02/-ABr03…) and its function against the Relion 615 ordering documentation — sibling codes differ in function.
- De-energize the IED and disconnect auxiliary supply before inserting or removing the module; follow ESD precautions.
- Insert the module into the designated slot of the IED; seat and latch it fully.
- Wire the binary inputs/outputs per the IED connection diagram, observing polarity and voltage class (24 V DC).
- After power-up, verify I/O status and configuration via the IED front panel / PCM600 before returning the protection to service.
