Preface

Thanks for using the MD300A series inverter presented by Inovance Technology Co., Ltd..

Developed on the basis of extensive market research, MD300A series inverter is a general-purpose

inverter with high performance.

Embodying the features of products offered by Inovance Technology Co., Ltd., the inverter bears

two control modes, that is, V/F and open-loop vector, and ensures the best low frequency torque

and dynamic response performance.

Many new functions have been added on the basis of the market research and analysis of the

customer’s function requirements. This series of products are the true high-performance inverters

with general-purpose function.

The manual presents the precaution details related to the installation, parameter adjustment,

abnormal problems diagnosis and daily maintenance of the inverter. Please carefully read the

manual before the installation and keep it safe for future maintenance reference.

Special precautions as follows:

 Do remember to cut off the power supply upon wiring. After cutting off the AC power, do not

touch the internal parts and components until at least 5 minutes later, since it takes some time

for the electric charge stored in the capacitor of the inverter to discharge.

 Do not touch the PCB or drop foreign material into the inverter, otherwise it may cause short

circuit, because many components inside the inverter are static sensitive devices.

 The grounding terminal of the inverter shall be reliably connected to the earth with multicore

cable.

 Do not connect AC input power to the output terminals U, V and W of the inverter.

 The external braking resistor can only be connected between terminal P and terminal PB.
