4.3.2 Things to note when wiring the main power supply

Make sure the controller has been discharged to below DC 30V before wiring.

A circuit breaker (MCCB) must be installed between the AC input power supply and the controller power input

terminals (R, S, T). The capacity of the circuit breaker (MCCB) must be greater than 1.5~2 times the rated

current of the controller.

The input power supply and the controller input terminals (R, S, T) can be connected arbitrarily (regardless of

the phase sequence), but the controller output terminals (U, V, W) must be connected to the motor in the

correct phase sequence considering the motor rotation direction. When you need to change the direction of

motor rotation, just change any two of the three phases at the controller output, or modify the inverter parameters.

Please do not short-circuit or ground the controller output terminals (U, V, W). Shortcircuiting or grounding the

output terminals will damage the controller and may cause personal injury accidents.

Please do not connect capacitors or filters to the output of the controller. Connecting capacitors or filters may

cause the controller to malfunction or damage the capacitors and filters.

The input and output ends of the controller should be connected with power cords of correct thickness. Using

a power cord that is too thin may result in reduced output power and may result in a fire due to overheating.

Please ensure that the length of the connection line between the controller and the motor is within 50m. If the

connection line is longer than 50m, you need to use an insulation-reinforced motor or a micro surge protection

filter.

4.3.3 Things to note when grounding wiring

The controller may have leakage when it is running, so the controller must have grounding measures to

prevent leakage.

The grounding resistance should be less than 10Ù during grounding.

The grounding wire must be a special grounding wire of specified thickness.
