3.Please use the shield wire or tube for the power wiring and ground the two ends of the shield wire or tube.

4.Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it comes in contact with high voltage.

5.The AC motor drive, motor and wiring may cause interference. To prevent the equipment damage, please take care of the erroneous actions of the surrounding sensors and the equipment.

6.When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor terminals U/T1, V/T2, and W/T3, respectively. To permanently reverse the direction of motor rotation, switch over any of the two motor leads.
