1.2 Warning Label
The warning label is on the front of the drive. Please read it carefully and follow the instructions.
◼ Read the user manual before operation.
◼ Risk of electrical shock. Shut off main power and wait for 5 minutes before servicing.
◼ Hot surface. Risk of burn.
1.3 AC Drive Application Precautions
1.3.1 AC Drive Selection
1.3.1.1 Drive Capacity
Before driving motors, ensure the motor rated current is lower than the drive rated output. In
addition, when a single AC drive is driving more than 1 motor in parallel, make sure the drive
capacity is higher than 110% of total motor rated current.
1.3.1.2 Starting Torque
◼ Do not connect three-phase power supply to terminals U, V and W. Failure to comply could damage
the drive.
◼ An output reactor is recommended when the cable connecting between the drive and motor is over
100 meters. Failure to comply could result in drive damage with overcurrent caused by over-
distributed capacitance.
◼ Never connect the output terminals to capacitors or unapproved LC/RC filters. Failure to comply could
damage the drive components.
◼ Separate the drive main circuit cables and control circuit cables. Failure to comply could cause
interference to the control signals
◼ Ensure the phase of power supply and rated voltage match the label on the drive. Failure to comply
could drive damage.
