professional training. Otherwise, it may cause personal injury or equipment damage.
● For all the standard equipped or optional accessories, must be dismounted or mounted while the
inverter power is disconnected.
1.3 General Precautions
1.3.1 Motor Insulation Inspection
For first time usage, motor is left unused for long time or periodically inspected, insulation inspection
must be done to avoid motor coils insulation failure which may result in inverter damage. Disconnect
motor and inverter before inspection, 500V voltage type Meg-ohmmeter is recommended. It is up to
standard if insulation resist value no less than 5MΩ.
1.3.2 Motor Overheat Protection
If selected motor and inverter rated capacity doesn’t match, especially the inverter rated power larger
than motor rated power, it is necessary to adjust the motor protect parameter of inverter into actual
used motor parameter. Or a thermal relay can be installed to motor to protect motor.
1.3.3 Run with Power Frequency (under or above)
This inverter can provide 0.00Hz~650.00Hz output frequency, so motor is run at low frequency on
long time. Take care of motor cooling or frequency converted motor could be a choice. When motor
run with over-limit rate frequency, consider the bearing capacity of mechanic system with high speed,
to avoid the shortening of lifespan of equipment.
1.3.4 Vibration and Resonance of Mechanic System
Since inherent property of mechanic system, inverter could have mechanic system resonance point
while accelerating or decelerating, by setting inverter jump frequency can avoid mechanic system
resonance point. If customer required run frequency is happened to be the same with mechanic
resonance frequency, it is necessary to change run frequency or change the inherent resonance
frequency of mechanic system.

1.3.5 Regarding Motor Heating and Noise
Inverter output voltage is PWM wave, with some higher harmonic, so motor temperature rising, noise
and vibration should increase a little comparing with power frequency, which is normal.
1.3.6 Pressure Sensing Device on Output Side or Improve Power Factor Capacitor
Inverter output voltage is PWM wave, if output side installed capacitor to improve power factor or
pressure sensing device to anti-thunder, it could easily result in instant over current or damage to
inverter. Disassemble such devices before inverter installation.
1.3.7 Switchover Device as Contactor Installed on Inverter Input Output Side
If there is a contactor between power supply and inverter input terminal, it is Disabled to use it to
start/stop inverter. When it is very necessary to use the contactor to start/stop inverter, the action
interval time should not less than 1hr. Since frequent charge/discharge could easily shorten the
lifespan of electrolytic capacitor inside inverter. If there is a contactor between motor and inverter
output terminal, make sure if motor is static and inverter is without output, then switchover the
contactor, failure to comply may damage the inverter.
1.3.8 Applications with Non-rated Voltage
The application voltage range used on inverter should not exceed the regulated voltage on this
manual, low voltage or higher voltage can easily damage inverter.
If power is not Enable, then use voltage reduction or voltage rising device to deal with voltage
conversion in order to comply with inverter input voltage requirement.
1.3.9 Three-phase Input Change to Two Phase Input
If inverter is 3phase input type, do not use 2phase power supply, otherwise it could result in phase
loss protection error even inverter damage.
1.3.10 Lightening Surge Protection
Although there is lightening overvoltage overcurrent device inside inverter, which has certain
self-protection function for lightening induction. But for user located in lightening frequent zones, it is
necessary to add lightening protection unit in front of inverter, this does good to extend inverter
lifespan.
1.3.11 Altitude Level and Voltage Reduction Usage
Place with altitude exceeding 2000M, inverter cooling effect get worse due to air condense reduced,
so under-rated usage of inverter is necessary.
1.3.12 Common DC Bus Introduction
In condition of several units of inverter run at the same time, then common DC bus can be adopted to
save electricity. This type of inverter support common DC bus, but make sure the power specification
of those inverters are very close in advance, otherwise it could damage inverter.
1.3.13 Precaution of Inverter Abandonment
Inverter belongs to electric electronic device, burning disposal will result lots of harmful gas even
exploding. Please refer to related national laws and regulations to dispose or abandon.
1.3.14 Regarding Adaptable Motor
①This type inverter standard matching motor is quaternary squirrel-cage asynchronous induction
motor or permanent magnet synchronous motor. When the dragging motor is not above type, please
refer to motor rated current to select the suitable inverter.
②The cooling fan of general motor and rotor spindle are coaxial connected. While motor rotating
speed reducing resulted cooling fan Deceleration proportionally and so making heat dissipation worse.
As a conclusion, if motor run at low frequency stage for long time, it is necessary to add a strong
exhaust fan or change the motor to variable frequency motor.
③Inverter default setup has built-in standard parameter for its adaptive motor, but in actual
application, it is necessary to identify motor parameter or change its original default setup of motor
parameter. Otherwise it affect operation efficiency and protection performance to motor.
④Due to cable or motor internal short circuit can result in inverter alarm or even exploding. So
insulation and short circuit test on wiring and motor should be done before connecting and installing
motor. If the system has been idled for long time, then a retest should be done to avoid system

WARNING
!
● Table 2-4 is a guide data, user can select different resistor value and power according to actual
situation.
● Selection of braking resistor is based on the motor generation power in actual application
system, it is related with system inertia, deceleration time, potential load energy, it is decided by
user’s actual situation.
● The greater the inertia of system, the required speed deceleration is shorter, the braking is more
frequent, so the braking resistor require a bigger power small value of resistor.
2.9 Routine Repair and Maintenance of Inverter
The influence of the ambient temperature, humidity, dust and vibration will cause the aging of the
devices in the inverter, which may cause potential fault of the inverter or reduce the service life of the
inverter. Therefore, it is necessary to carry out routine and periodical maintenance on the inverter, it
must be regularly maintenance for every 3~6 months.
