How does the self‑test work when the load is powered on?
When the load is powered on, a system self‑test runs for about one second; if EEPROM or calibration data are missing, the VFD displays error messages.
How can the fuse be replaced?
Remove the small plastic cover under the rear power socket with a flat‑head screwdriver, locate the fuse, and replace it with one matching the specified rating.
