1.2 Cautions

1.2.1 Check the Insulation of the Motor

When the motor is used for the first time or reused after storing for a long time , you must check the

insulation of the motor . It is recommended to use a 500V Mega-

Ohm-Meter to check and the measured

insulation resistance shall not be less than 5M .Ω

1.2.2 Thermal Protection of Motor

1.2.3 Running above Rated Frequency

1.2.4 Vibration of the Mechanical Device

1.2.5 Pressure-sensitive Device or Capacitor Improving Power Factor at the

1.2.6 Switching Devices like Contactors Used at the Input and Output Ends

1.2.7 Change three phase Input into two phase Input

1.2.8 Altitude and Deration

Output Side

If the ated capacity of the motor , especially when the ratedselected inverter is not matching the r power

Please consider the capability of the mechanical devices when you need the inverter to run at the frequency

If the inverter encounters the resonance point of load device within a certain output frequency range .

Since the inverter output is PWM wave , the capacitor for improving the power factor or pressure-

If the contactor is required to be installed between the inverter and the power supply , it is prohibited to

start or stop the inverter with the contactor . If the user has to use the contactor to start and stop the

inverter , the interval shouldn`t be less than an hour . Frequent charging and discharging may reduce

the service life of the capacitor . If the switches like contactors are equipped between the output

terminal and the motor , make sure to start and stop the inverter when it has no output ,otherwise the

modules in the inverter may be easily damaged .

It is not allowed to change the three phase inverter into two phase one . Otherwise , it may cause fault or

When the altitude is higher than 1000m , the cooling effect of inverter is deteriorated due to the rarefaction

of air , the derating using is necessary and please consult our company for detailed technical support .

damage the inverter .

sensitive resistor for lightening-proof shouldn`t be installed at the output side of the inverter ,otherwise

it is easy to cause transient over current and even damage the inverter . Don`t use it!

You can avoid that by frequency parameters in the inverter .configuring the hopping

higher than 50Hz .

of the inverter is higher than that of the motor ,make sure to adjust the parameters for motor protection in the

inverter or to install thermal relay to protect the motor .

Chapter 1 Safety and Cautions

1.2.9 Check the Insulation of the Motor

The cooling fan and the rotor shaft of the non-variable-frequency motor are coaxially connected . When

the rotating speed is reduced , the cooling effect will be poorer . Therefore , a powerful exhaust fan should

be installed or the motor should be replaced with variable-frequency motor to avoid the over heat

of the motor .

1) There are two kinds of electromagnetic interferences , one is interference of electromagnetice noise

2) Handling method for the interferences of the surrouding equipment on the inverter :

3) Handling method for the interferences of inverter on the surrounding equipment :

A The earth wires of the inverter and other electric products should be well grounded ,the resistance、

A For the measuring meters , receivers and sensors , their signals are generally weak . If they are placed、

B When the epuipment suffering interferences and the inverter use the same power supply , it may、

linearity filter or wireless noise filter between the inverter and the power supply .

nearby the inverter or together with the inverter in the same control cabinet , they are easy to suffer

interference and thus generate error actions . it is recommended to handle with the following methods :

keep it far away from the interference source ; do not arrange the signal cables with the power cables

in paralled and never bind them together ; both the signal cables and power cables employ shielded cables

are well earthed; install linearity filter or wireless noise filter at the input/output side of inverter .

B Install filter at the input end of the inverter .、 C The lead cables of the control signal cable of the inverter and the detection line employ shielded、

cable and the shielding layer should be earthed reliably .

B The power cables and control line should not be arranged in paralled and vertical arrangements is、

C For high-demanded anti-interference places, it is recommended that the output power cables of the inverter employ shield cables and the、shielding

layer must be earthed reliably .

D For the lead cables of the equipment which are suffering interferences, it is recommended to employ twisted-pair、

shielded control cables ,and the shielding layer should be earthed reliably .

should be less than 5 .Ω

in the surrounding environment to the inverter ,it maybe cause error action ,however, the impact is usually small, because

The electromagnetic interference on the inverter generated because of plenty of relays , contactors

These interferences include two types : one is radiation interference of the inverter , and the other is

conduction interference of the inverter . These two types of interferences cause the surrounding electric

equipment to suffer electromagnetic or electrostatic induction . The surrounding equipment hereby produces

error action . For different interferences , it could be handled by referring to the methods :

and electromagnetic brakes are installed near the inverter . When the inverter has error action

due to the interferences , the following measures can be taken :

the inverter has internal handling when it is designed , so it has strong anti-interference capability for

itself ; and the other is interference of inverter on the surrounding equipment .

Common approach :

C The surrounding equipment is separately earthed , which can avoid the interference caused by the、

leakage current of the inverter’s earth wire when common earth mode is adopted .

There are two forms of leakage current when using the inverter . One is leakage current to the earth,

and the other is leakage current between the cables .

There are distributed capacitance between the lead cables and the earth . The larger the distributed

The leakage current may increase along with the addition of circuit current . Therefore , when motor

lines has higher harmonic , it may cause resonance and thus result in leakage current . if thermal relay is

used , it may generate error action .

power is high , the corresponding leakage current will be high too .

capacitance is , the larger the leakage current will be . The distributed capacitance can be reduced by

effectively reducing the distance between the inverter and the motor . The higher the carrier frequency is,

the larger the leakage current will be . The leakage current can be reduced by reducing the carrier frequency .

However , reducing the carrier frequency may result in addition of motor noise . Note that additional

installation of reactor is also an effective method to remove the leakage current .
