6.1.2 Reforming before commissioning
If annual reforming is not possible, implement reforming on stored devices before commissioning. Note that the voltage
levels depend on the storage time.

Fig.5: Voltage levels dependent on storage time
1 Storage time of 1–2 years: Apply voltage for 1 hour before switching on.
2 Storage time of 2–3 years: Implement reforming according to the graph before switching on.
3 Storage time ≥3 years: Implement reforming according to the graph before switching on.
Storage time <1 year: No actions required.
Information
For UL-compliant operation: The connections marked with PE are intended solely for the functional grounding.
