|---|---|---|---|---|
| Overload protection button | Unstable grid voltage, such as from lightning, or a large voltage input at the AC terminal trips the overload protection (safety circuit breaker). It disconnects the AC input port from external devices. | Turn off the power button and unplug all ports. After confirming no part is abnormal, turn the power button on. Press the overload protection button and turn on the AC cable to resume AC input. | owner | p. 6 |
| High temperature protection | The internal temperature is too high or too low. The intelligent protection program forces the machine to stop working normally. | Wait for the machine to return to normal temperature, then you can start working again. Keep both side air inlets unblocked. | owner | p. 7 |
| Low temperature protection | The internal temperature is too low or too high. The intelligent protection program forces the machine to stop working normally. | Wait for the machine to return to normal temperature, then you can start working again. | owner | p. 7 |
| Overload Overload (UPS mode) | In UPS mode, AC output above 1400W (US/Japan standard) or 2000W (other standards) makes the UPS icon flash. The AC icon goes out and output is interrupted. | Check the load situation. Reduce the connected AC load so it stays within the stated limit. | owner | p. 8 |
