Installation

• Before wiring, ensure the input power supply is switched off.
• Wiring must be carried out by professional electrical technicians.
• The grounding terminal must be properly connected.
• Check that the AC main circuit supply voltage is compatible with the inverter's rated voltage.
• Do not connect the power cord to the U, V, and W output terminals.
• Be sure to install the protective cover before powering on.

Operation

• The drive is equipped with a user-friendly keypad with a digital display for easy operation.
• Do not touch the inverter terminals, as they are under high voltage.
• After confirming that the operating signal is broken, the alarm can be reset.

Other Information

• The drive features a large heat sink, approximately three times larger than those of similar products, and a small, low-noise fan for efficient heat dissipation.
• It is important not to perform a withstand voltage test on the inverter.
• Do not connect the contactor to the output circuit.
• When removing the cover, disconnect the power supply to avoid any risk.
