Security Tips
- Only qualified personnel can operate the equipment.
- AC power supply should not be connected with output ports U, V, and W, otherwise, there is a danger of damage to the frequency inverter.
- After electrified, it is forbidden to contact the internal wiring board and its parts. Otherwise, it will cause the danger of electric shock
- The user can only operate on it after 5 minutes when cutting off power.

on again)
Trial Run
- Please double-check the cable connector according to the user manual.
- Press the “Start/Stop” button to run it, and check whether the pump rotary direction is correct. If the direction is correct, please go to step(4); Otherwise, please go to step (3).
- Press the “Start/Stop” button to stop it and change any two cables to adjust the direction; Press the “Start/Stop” button and then it will run smoothly.
- The default setting for Start/Stop will store the operation command while power off. So it will automatically run or stop along with sunrise or sunset.
Quick Troubleshooting
- Power is still off when connecting power: please check whether the input voltage is 60-400VDC or check the cable connections of the solar array.
- Status indicator is blinking: please reset it by pressing “START/STOP” for 1 second. Otherwise, please ask for support.
