Installation handover
Isolate the circuit or process before touching FH202 AC-25/0.03; follow the site's approved safety procedure. Record cable labels, settings, accessory positions and original markings.
When FH202 AC-25/0.03 is fitted, restore the approved configuration and make sure installation details match the drawings. Keep removed parts until the acceptance result is signed off.
Replacement compatibility review
For FH202 AC-25/0.03, compare neutral routing, residual waveform, rated current, upstream protection and earthing system. Check the complete order code, not only the family prefix.
A proposed substitute for FH202 AC-25/0.03 requires a documented comparison of electrical or process rating, terminals, communications, mechanical fit and any required settings.
Observed fault and process consequence
In this installation, FH202 AC-25/0.03 is intended to provide residual-current protection for the selected single-phase circuit. Write down the fault indication, operating state and last known good reading before removal.
If FH202 AC-25/0.03 trips or loses communication intermittently, separate wiring and supply faults from device faults. Capture the relevant alarm history and field measurements.
Acceptance evidence
The practical test for FH202 AC-25/0.03 is to perform the test-button and instrumented trip checks under the site procedure. Log the expected result, actual result, date and responsible technician.
Do not close a FH202 AC-25/0.03 replacement ticket on visual inspection alone. Confirm the normal function and the planned failure or alarm response where safely testable.
