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

Trial Run
（1）Please double check the cable connection according to user
manual.
（2）Press “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）.
（3）Press “Start/Stop” button to stop it and change any two cables to
adjust the direction；Press “Start/Stop” button and then it will run
smoothly.
（4）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
（1）Power is still off when connecting power: please check whether the
input voltage is 60-400VDC or check cable connections of solar array.
（2）Status indicator is blinking: please reset it by pressing
“START/STOP” for 1 second. Otherwise，please ask for support.
