Serial Range | Mode | Details |
> BBE20001560 | 4‑Wire WYE | Terminate L1, L2, L3 and N on their respective terminals. Remove any N–A bond. |
≤ BBE20001560 | Delta (N bonded to A) | Keep internal N–A bonding strap. Terminate only L1/A, L2/B, L3/C. |
📋 Verification Steps
After wiring each unit, always:
Measure phase‑to‑phase voltages (L1–L2, L2–L3, L3–L1)
Measure phase‑to‑neutral voltages on 4‑wire WYE units (L1–N, L2–N, L3–N)
Confirm no unexpected faults or trips on the EDG.
📝 Notes & Best Practices
Follow local electrical codes and LOTO procedures.
If in doubt about your unit’s serial, contact Verdigris Support with serial + firmware version.
