Confirm that the ABB REF615 HBFEAEAGABB1BNA11E is correctly installed, wired and grounded in the switchgear panel according to the project drawings.

Apply the auxiliary supply to the REF615 HBFEAEAGABB1BNA11E and verify that the front HMI starts up and shows a healthy status.

Connect a configuration PC and load or adjust the settings and logic of the ABB REF615 HBFEAEAGABB1BNA11E based on the feeder data and protection coordination study.

Check measured values, indications and breaker status on the HMI of the REF615 HBFEAEAGABB1BNA11E to confirm that signals from CTs, VTs and control circuits are correct.

Perform secondary injection tests and functional checks to verify that the ABB REF615 HBFEAEAGABB1BNA11E trips, signals and communicates as specified.

After successful testing, place the REF615 HBFEAEAGABB1BNA11E into service and archive the final configuration and setting reports.

Install the ABB REF615 HBFEAEAGABB1BNA11E in a clean, dry and vibration free switchgear or control panel that meets the specified environmental limits.

Ensure adequate space for ventilation and front access around the REF615 HBFEAEAGABB1BNA11E, especially for viewing the display and operating the keypad.

Use the recommended panel cut out and mounting hardware when fitting the case, then insert the plug  in unit of the ABB REF615 HBFEAEAGABB1BNA11E fully and secure it according to the instructions.

Separate control, CT/VT and communication wiring of the REF615 HBFEAEAGABB1BNA11E from high power cables to minimize electromagnetic interference.

Always de energize relevant circuits and follow local safety and lockout tagout procedures before installing or removing the ABB REF615 HBFEAEAGABB1BNA11E.

Visually inspect the ABB REF615 HBFEAEAGABB1BNA11E and its terminals periodically for dust, loose connections or signs of overheating.

Review event lists, disturbance records and alarms stored in the REF615 HBFEAEAGABB1BNA11E to detect abnormal operation or repeated faults.

During scheduled maintenance, verify key protection and control functions of the ABB REF615 HBFEAEAGABB1BNA11E using approved secondary test equipment.

Keep configuration files, setting reports and firmware information for each REF615 HBFEAEAGABB1BNA11E properly backed up to simplify replacement or recovery.

When network topology or protection philosophy changes, update and re validate the settings of the ABB REF615 HBFEAEAGABB1BNA11E under a controlled changemanagement process.
