t
NOTICE
-Comply with ESD protection specifications and power distribution
ESD bracelets.
- Avoid unnecessary contact with the circuit board.
-Touching printed circuit boards or other electrostatic sensitive
components may cause damage during the process.
8.1 Troubleshooting
If the inverter is break down, the LED indicator will turn to red.
Alarm
Information
1.If the alarm occurs accidentally, possibly the power grid is abnormal
accidentally. No extra action is needed.
2.If the alarm occurs repeatedly, contact the local power station. After receiving
approval of the local power bureau, revise the electrical protection parameters
setting on the inverter through APP.
3.If the alarm persists for a long time,please confirm:
A0-Grid over
1) The AC circuit breaker does not jump frequently (the instantaneous high
voltage
pressure);
2) If the line of communication is followed by the user manual, the cable
impedance will cause the power grid to rise;
3) The three-phase machine measures whether the voltage between the zero
line and the ground line exceeds 30V; More than the wiring of the grid; If there
is no problem, Pls.contact the customer service center

2) Whether the AC circuit breaker is damaged (whether the voltage in the
closed state is consistent with the voltage of the outlet);
3) The AC terminals are in good contact.
If the actual measuring voltage is within the specification range, please contact
the customer service report repair
