Declaration

Thanks for choosing the inverter Before you use it, please read the instructions carefully, and making sure that you have known about all the safety precaution.

Safety Precaution:

1 Before wring, please make sure that the input power is off.

2 The wring work should be operated by the professional electrical engineer.

3 The grounding terminals must be connected with the ground.

4 Having paused circuit wiring emergently, please make sure that the check is effective.

5 Do not connect the output wire of the inverter with the shell, and pay attention that the output wire should not be short-circuited.

6 Please check whether the voltage of the AC main circuit power is consistent with the rated voltage of the inverter.

7 Do not do the voltage withstand test on the inverter.

8 Please connect the brake resistor according to the wiring diagram.

9 Do not connect the power to the U, V, W output terminals.

10 Do not connect the contactor with the output circuit.

11 Mare sure to install a protection cover before power-on When removing the cover, be sure to make the power off.

12 If you want to reset the inverter with the retry function, do not get close

to the mechanical equipment, because the inverter will restart suddenly when the alarm stops.

13 Confirmthat the operation signal is cut off Before reset the alarm device, or the inverter may start suddenly.

14 Do not touch the terminals of inverter, which are very dangerous because there is high voltage on them.

15 When power is on, do not change the wiring and terminal.

16 Cut off the main circuit power before doing some check and maintain work.

17 Do not arbitrarily reform the inverter.

3、Operation

Attention:

If the power is on, it shows 0.0 on the panel (output frequency)

After setting parameter, the way to return the original:

1 When the power is off, make it on again

2 Select the parameter d-00, and click SET

3 Long press SET key for 3 S

Inverter operation command mode is set by parameter F0.02: There are two kinds

of command mode: panel control start / stop and terminal control start / stop:

(1) Panel control start/stop: (The factory set defaults to be controlled by panel.)

When you use the panel to control the inverter, you should remember thatclicking the green button means start the inverter and clicking the red button meansstop Before any operation, the inverter defaults to start FWD FWD and REV are set

by input terminal S1-S5 (the REV set is 4)

The inverter frequency setting mode is set by F0.03 When F0.03 = 0, the runningfrequency is set by potentiometer When F0.03 = 3, the running frequency is input byAVI (0-10V can be connected with potentiometer); when F0.03 = 5, the runningfrequency is input by ACI (4-20mA) When F0.03 = 2, it is controlled by the externalterminal (the switch value is set to frequency increment / decrement)
