1.2 General Precautions
1.2.1 Motor insulation test
Perform the insulation test when the motor is used for the first time, or when it is reused after being stored for a
long time, or in a regular check-up, in order to prevent the poor insulation of motor windings from damaging the
frequency inverter. The motor must be disconnected from the frequency inverter during the insulation test. A
500-V mega-Ohm meter is recommended for the test. The insulation resistance must not be less than 5 MΩ.
1.2.2 Thermal protection of motor
If the rated capacity of the motor selected does not match that of the frequency inverter, especially when the
frequency inverter's rated power is greater than the motor's, adjust the motor protection parameters on the
operation panel of the frequency inverter or install a thermal relay in the motor circuit for protection.
1.2.3 Running at over 50 Hz
The frequency inverter provides frequency output from 0 to 3200 Hz with V/F mode (300 Hz is supported for
frequency inverter running at FVC and SVC mode). If the frequency inverter is required to run at over 50 Hz,
please consider the bearable capacity of the machine.
1.2.4 Vibration of mechanical device
The frequency inverter may encounter the mechanical resonance point at some output frequency points, which can
be avoided by setting the skip frequency.
1.2.5 Motor heat and noise
The output of the frequency inverter is pulse width modulation (PWM) wave with certain harmonic frequencies,
and therefore, the motor temperature, noise, and vibration are slightly greater than those motor runs at grid power
frequency (50 Hz).
1.2.6 Voltage-sensitive device or capacitor at output side of the Frequency inverter
Do not install the capacitor for improving power factor or lightning protection voltage-sensitive resistor at the
output side of the frequency inverter because the output of the frequency inverter is PWM wave. Otherwise, the
frequency inverter may suffer transient over current and even to be damaged.
1.2.7 Contactor at the Input or Output side of the frequency inverter
When contactor is installed between the input side of the frequency inverter for the power supplying, the
frequency inverter must not be started or stopped by the contactor switching on or off. If the frequency inverter
has to be operated by the contactor, ensure that the time interval between switching is at least one hour. Since
frequently charge and discharge will shorten the service life of the capacitor inside of the frequency inverter.
When a contactor is installed between the output side of the frequency inverter and the motor, do not turn off the
contactor when the frequency inverter is running. Otherwise, IGBT modules inside of frequency inverter may be
damaged.
1.2.8 When input voltage is over rated voltage range
The frequency inverter must not be used over the allowable voltage range specified in this manual. Otherwise, the
frequency inverter's components may be damaged. If required, please use a corresponding voltage transformer
device.
1.2.9 Prohibition of three-phase input changed into two-phase input
Do not change the three-phase power input of the frequency inverter to two-phase input. Otherwise, frequency

inverter will be damaged.
1.2.10 Surge suppressor
The frequency inverter has a built-in voltage sensitive resistor for suppressing the surge voltage. Using frequently
surge place, please add extra surge voltage protection device at input side of frequency inverter.
Note: Do not add the surge suppressor at the output side of the frequency inverter.
1.2.11 Altitude and de-rating using
Where the altitude is above 1000 m and the cooling effect WEAKEN due to thin air, it is necessary to de-rate the
power of frequency inverter. Please contact our company for technical supporting.
1.2.12 Some special application
If wiring that is not described in this manual such as shared DC bus is applied, please contact the agent or our
company for technical supporting.
1.2.13 Scrap disposition
The electrolytic capacitors on the main circuit and PCB board may explode when they are burning. Poisonous gas
is generated when the plastic parts are burning. Please treat them as industrial waste by special way.
1.2.14 Matched Motor
The standard matched motor is suitable four-pole squirrel-cage asynchronous induction motor. For other types of
motor, please select a proper frequency inverter according to the rated motor current. If user uses inverter for
permanent magnet synchronous motor, please contact my company for selecting another series inverter..
The cooling fan is coaxial to rotor shaft of non-variable-frequency motor, which will reduce cooling effect when
the shaft rotational speed decreasing. If motor is required variable speed, add a separately cooling fan or replace
motor to variable-frequency motor.
The common standard parameters of the matched motor have been configured inside the frequency inverter. It is
still necessary to perform motor auto-tuning or modify the default values based on actual application. Otherwise,
the running result and protection performance will be weaken.
The frequency inverter may alarm and even be damaged when short-circuit exists on cables or inside the motor.
Therefore, perform insulation test when the motor and cables are newly installed or during routine maintenance.
During the test, make sure the frequency inverter is disconnected from the tested parts.

2.5 Daily maintenance of frequency inverters
2.5.1 Daily maintenance
Due to the influence of temperature, humidity, dust and vibration, it will lead to poor heat dissipation and
component aging of frequency inverter, and results in potential failure or reducing the service life of frequency
inverter. Therefore, it is necessary to do daily and regular maintenance of the frequency inverter.
Daily check items:
1. Check if the frequency inverter sound is normal during the running of the motor;
2. Check if there is a vibration during the running of the motor;
3. Check whether the installation environment of frequency inverter has changed;
4. Check if the cooling fan of frequency inverter is working correctly, the cooling air duct is clear;
5. Check if the frequency inverter is overheating;
6. Make sure that the frequency inverter should always be kept in a clean state;
7. Clear up effectively the dust on the surface of the frequency inverter, prevent the dust from entering into the
inside of the frequency inverter, especially for the metal dust;
8. Clear up effectively the oil and dust on the cooling fan of frequency inverter.
2.5.2 Regular inspection
Please regularly check frequency inverter, especially for the difficult checking place during running.
Regular inspection items:
1. Check the air duct and clear up regularly;
2. Check if there are any loose screws;
3. Check if the inverter has been corroded;
4. Check whether the wiring terminals show signs of arcing.
Note: When using the megger(please use the DC 500V meg ohm meter) to measure the insulation resistance, you
shall disconnect the main circuit to the frequency inverter. Do not use the insulation resistance meter to test the
control circuit. Do not to do the high voltage test (It has been done when the frequency inverter producing in
factory.)
2.5.3 Replacement of wearing parts
The vulnerable parts of frequency inverter include the cooling fan and filter electrolytic capacitor, its service life is
closely related to the using environment and maintenance status. The general service life is:
Part Name
Service Life
Fan
3 to 4 Years
Electrolytic capacitor
5 to 6 Years
The user can confirm the replace time according to the running time.
1. Possible reasons for the damage of cooling fan: bearing wear and blade aging. Distinguish standard: Any
cracks in the fan blade, any abnormal vibration sound during the starting of frequency inverter.
2. Possible reasons for the damage of filting electrolytic capacitor: poor quality of the input power supply, the
environment temperature is higher, the load change frequently and the electrolyte aging. Distinguish standard:
Any leakage of its liquid, if the safety valve is protruding, please test capacitor electrostatic capacitance and
insulation resistance.
2.5.4 Storage of the frequency inverter
After buying the frequency inverter, users shall pay attention to the temporary and long-term storage as following:
1. Store the frequency inverter in the original packaging;

EM15 User’s Manual 2. Product Information
13
2. Long-term storage can lead to the degradation of electrolytic capacitors, and must ensure to power on for once
within 2 years. And the power-on time is at least 5 hours. The input voltage must slowly rise to the rating by
using the voltage regulator.
2.6 Selection Guide of braking component
Table 2-5 is the recommended value of braking resistor, users can select the different resistance value and power
according to the actual situation,(but the resistance value must not be less than the recommended value in the table,
and the power can be bigger.) The selection of braking resistance need to be confirmed according to the power
that the motor generated in the practical application systems, and is relevant to the system inertia, deceleration
time, the energy of the potential energy load, needs customers to choose according to actual situation. The greater
the inertia and the shorter deceleration time is needed more frequently braking, so the braking resistor needs the
one with bigger power but smaller resistance value.
2.6.1 Selection of braking resistance value
When braking, almost all the regenerated energy of motor is consumed by the braking resistor.
According to the formula: U * U/R = Pb
In the formula:
U --- The braking voltage when the system brake stably (different system is different, for the 380VAC system
generally take 700V)
R - Braking resistor value
Pb –Power of braking(W)
2.6.2 Selection power of braking resistor
In theory the power of braking resistor is consistent with the braking power, but it need to be taken into
consideration that the braking resistor power will derate to 70%.
According to the formula: 0.7*Pr=Pb*D
In this formula:
Pr----Power of resistor
D---- Braking proportion (the proportion that the regeneration process accounts for the whole process)
Elevator---- 20%~30%
Uncoiling and coiling machine---- 20%~30%
Centrifugal machine---- 50%~60%
Occasionally braking load---- 5%
Other machine generally-----10%
