1.2 Precautions
1.2.1 Motor Insulation Inspection
When the motor is used for the first time or when the motor is reused after being kept, or
when periodical inspection is performed, insulation inspection shall be conducted with motor
so as to avoid damaging the inverter because of the insulation failure of the motor windings.
The motor wires must be disconnected from the inverter during the insulation inspection. It is
recommended to use the 500V mega meter, and the insulating resistance measured shall be
5MΩ at least..
1.2.2 Motor Thermal Protection

YX3000 Senseless Vector Type Inverter Manual
- 9 -
If the motor rating does not match that of the inverter, especially when the rated power of the
inverter is higher than that of the motor, adjust motor protection parameters in the inverter or
install thermal relay to protect motor.
1.2.3 Operating with the Frequency Higher than Grid Power Frequency
Output frequency of YX3000 is 0.00Hz ～500Hz. If YX3000 is required to operate above
50.00Hz, please take the endurance of mechanical devices into consideration.
1.2.4 Mechanical Vibrations
Inverter may encounter mechanical resonance point of the load device at certain output
frequencies which can be avoided by setting the skip frequency parameters of the inverter.
1.2.5 Motor Heat and Noise
Since output voltage of inverter is PWM wave and contains a certain amount of harmonics,
so that the temperature, noise and vibration of the motor will be higher than those when the
inverter runs at grid power frequency.
1.2.6 Voltage-sensitive device or capacitor on output side of the AC drive
Do not install the capacitor for improving power factor or lightning protection
voltage-sensitive resistor on the output side of the AC drive because the output of the AC
drive is PWM wave. Otherwise, the AC drive may suffer transient overcurrent or even be
damaged.
1.2.7 Contactor at the I/O terminal of the AC drive
When a contactor is installed between the input side of the AC drive and the power supply,
the AC drive must not be started or stopped by switching the contactor on or off. If the AC
drive has to be operated by the contactor, ensure that the time interval between switching is
at least one hour since frequent charge and discharge will shorten the service life of the
capacitor inside the AC drive.
When a contactor is installed between the output side of the AC drive and the motor, do not

YX3000 Senseless Vector Type Inverter Manual
- 10 -
turn off the contactor when the AC drive is active. Otherwise, modules inside the AC drive
may be damaged.
1.2.8 Applied with the Rated Voltage
Apply YX3000 with the rated voltage. Failure to comply will damage inverter. If required, take
a transformer to boost or step-down voltage.
1.2.9 Do Not Apply a 3-Phase Input Inverter to 2-Phase Input Applications
Do not apply a 3-phase input FR inverter to 2-phase input applications. Otherwise, it will
result in faults or damage inverter.
1.2.10 Lightning Protection
YX3000 has integrated lightning over-current protection device which has certain
self-protection capacity against the lightning. Additional protection devices have to be
installed between inverter and power supply in the area where lightning occurs frequently.
1.2.11 Altitude De-rating
In places where the altitude is above 1000 m and the cooling effect reduces due to thin air,
it is necessary to de-rate the AC drive. Contact YUANXIN for technical support.

If wiring that is not described in this manual such as common DC bus is applied, contact the
agent or YUANXIN for technical support.
1.2.13 Cautions for Inverter Disposal
The electrolytic capacitors on the main circuit and PCBA may explode when they are burnt.
Emission of toxic gas may be generated when the plastic parts are burnt. Please dispose
inverter as industrial wastes.
1.2.14 Adaptable Motor
The standard adaptable motor is adaptable four-pole squirrel-cage asynchronous induction
motor or PMSM. For other types of motor, select a proper AC drive according to the rated
motor current.
The cooling fan and rotor shaft of non-variable-frequency motor are coaxial, which results in
reduced cooling effect when the rotational speed declines. If variable speed is required, add
a more powerful fan or replace it with variable-frequency motor in applications where the
motor overheats easily.
The standard parameters of the adaptable motor have been configured inside the AC drive. It
is still necessary to perform motor auto-tuning or modify the default values based on actual
conditions. Otherwise, the running result and protection performance will be affected.
The AC drive may alarm or even be damaged when short-circuit exists on cables or inside
the motor. Therefore, perform insulation short-circuit test when the motor and cables are
newly installed or during routine maintenance. During the test, make sure that the AC drive is
disconnected from the tested parts.
