1.2 Precautions
1）Leakage protector RCD requirements
The device will generate large leakage current flowing through the protective grounding conductor
during operation. Install a Type B residual current protector (RCD) on the primary side of the power
supply. When selecting a leakage protector (RCD), consider the transient and steady-state earth
leakage currents that may occur during startup and operation of the equipment, select a dedicated
RCD with high harmonic suppression, or a common RCD with large residual current.
2）Motor insulation inspection

JAC300 Series Inverter User Manual
- 8 -
After the motor is used for the first time, before being used for a long time, and before the
periodic inspection, the motor insulation inspection should be done to prevent damage to the
inverter due to insulation failure of the motor winding. When checking the insulation, be sure to
separate the motor wiring from the inverter. It is recommended to use 500V.For the stamped
megger, the measured insulation resistance shall be not less than 5 MΩ.
3）Thermal protection of the motor
If the selected motor does not match the rated capacity of the inverter, especially when the rated
power of the inverter is greater than the rated power of the motor, be sure to adjust the parameter
value of the motor protection in the inverter or install a thermal relay in front of the motor to protect
the motor.
4）Operating above the power frequency
The inverter provides an output frequency of 0Hz~500Hz. If the customer needs to operate above
50Hz, please consider the bearing capacity of the mechanical device.
5）Mechanical vibration
At some output frequencies, the inverter may encounter the mechanical resonance point of the load
device, which can be avoided by setting the jump frequency parameter in the inverter.
6）About motor heating and noise
Because the output voltage of the inverter is PWM wave and contains certain harmonics, the

JAC300 Series Inverter User Manual
- 9 -
temperature rise, noise and vibration of the motor will increase slightly compared with the power
frequency operation.
7）The case where the output side has a pressure sensitive device or a capacitor with
improved power factor
The output of the inverter is PWM wave. If the output side is equipped with a capacitor with
improved power factor or a varistor for lightning protection, it may cause the inverter to over-current
or even damage the inverter. Please do not use.
8）Switching devices such as contactors used at the input and output of the inverter
If a contactor is installed between the power supply and the input of the inverter, this contactor is not
allowed to control the start and stop of the inverter. It is necessary to use this contactor to control the
start and stop of the inverter, and the interval should not be less than one hour. Frequent charging
and discharging tends to reduce the service life of the capacitors in the inverter. If a switching device
such as a contactor is installed between the output terminal and the motor, ensure that the inverter
performs the on/off operation when there is no output, otherwise the module inside the inverter may
be damaged.

9）Use outside of rated voltage
It is not suitable to use the inverter outside the allowable working voltage range specified in the
manual, which may cause damage to the components inside the inverter. If needed,Please use the
corresponding step-up or step-down device to transform the power supply and input it to the inverter.
10）Three-phase input changed to two-phase input
Do not change the three-phase inverter to two-phase. Failure to do so will result in malfunction or
damage to the inverter.
11）Lightning shock protection
Although the inverter is equipped with lightning overcurrent protection device, it has certain
self-protection ability for the induction lightning. However, for frequent lightning, the customer should
also install lightning protection device at the front end of the inverter.
12）Altitude and derating
In areas where the altitude is more than 1000 m, the heat dissipation effect of the inverter is
deteriorated due to the thin air, and it is necessary to derate the use. Please contact us for technical
consultation in this case.
13）Some special usage
If the customer needs to use the method other than the recommended wiring diagram provided in
this manual, such as the common DC bus, please consult with us.
14）Pay attention to the inverter when it is scrapped
The electrolytic capacitor of the main circuit and the electrolytic capacitor on the printed circuit board
may explode when incinerated. Toxic gases are generated when plastic parts are incinerated.
Please dispose of it as industrial waste.

15）About the adapter motor
●The standard adapter motor is a four-pole squirrel cage induction motor. If it is not the above
motor, please select the inverter according to the rated current of the motor.
●The cooling fan of the non-inverter motor is coaxially connected with the rotor shaft. When the
speed is reduced, the cooling effect of the fan is reduced. Therefore, if the motor is overheated, a
strong exhaust fan or a variable frequency motor should be installed.
●The inverter has built-in matching motor standard parameters. According to the actual situation, it
is necessary to identify the motor parameters or modify the default values to match the actual values
as much as possible. Otherwise, the operation effect and protection performance will be affected.
●The inverter will alarm or even blow up the machine due to a short circuit inside the cable or
motor. Therefore, first perform the insulation short-circuit test on the initially installed motor and
cable, and also perform this test frequently in routine maintenance. Note that it is important to
disconnect the drive from the part under test when doing this test.

Chapter 3 Installation Instructions
3.1 Mechanical installation
3.1.1 Installation Environment
1） Ambient temperature: The ambient temperature has a great influence on the life of the inverter.
The operating environment temperature of the inverter is not allowed to exceed the allowable
temperature range (-10 °C to 50 °C).
2）Install the inverter on the surface of the flame-retardant object, and have enough space
around it to dissipate heat. The inverter is prone to generate a lot of heat when it is working.
It is mounted vertically on the mounting bracket with screws.
3） Please install it in a place where it is not easy to vibrate. The vibration should be no more than
0.6G. Pay special attention to equipment such as punching machines.
4）Avoid being placed in direct sunlight, moisture, or water.
5）Avoid places that are corrosive, flammable, or explosive in the air.
6）Avoid installation in places with oil, dust, and metal dust.
7）JAC300 series plastic casing products are Built-in products, which need to be installed in the
final system. The final system should provide corresponding fireproof casing, electrical
protective casing and mechanical protective casing, etc., and comply with local laws and
regulations and relevant IEC standards.
