12. For the single-phase applications, the AC input line can be connected to any two of the
three input terminals R/L1, S/L2, T/L3.
Note: This drive is not intended for the use with single-phase motors.
13. Route the power and control wires separately, or at 90°angle to each other.
14. If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close
as possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.
15. If the AC drive is installed in the place where a load reactor is needed, install the filter
close to U/T1, V/T2, W/T3 side of AC drive. Do not use a Capacitor or L-C Filter
(Inductance-Capacitance) or R-C Filter (Resistance-Capacitance).
16. When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with not less
than 200mA, and not less than 0.1-second detection to avoid nuisance tripping
3.6 Motor Operation Precautions
1. When using the AC drive to operate a standard 3-phase induction motor, notice that the
energy loss is greater than an inverter duty motor.
2. While using the standard induction motor at low speed, the temperature of the motor
may rise, so do not operate the motor at low speed for a long period of time.
3. When the standard motor operates at low speed, the motor output torque will decrease,
please decrease the load during the operation.
4. If 100% output torque is desired at low speed operation, it may be necessary to use a
special motor that can handle this load (inverter duty).
