1.3 Notes
A. Insulation checking of motors
Before using the drive, the insulation of the motors must be checked,
especially, if it is used for the first time, if it has been stored for a long
time or regularly check. This is to reduce the risk of the drive from being
damaged by the poor insulation of the motor. When checking ,must make
sure the motors and the drive is separated, Please use 500V insulation
tester to measure the insulating resistance. It should not be less than 5MΩ.
B. Motor thermal protection
If the ratings of the driven motor are not in compliance with the drive,
especially, the drive rated power more than motor rated power, be sure to
adjust the protective threshold or to install thermal relay before the motor
to ensure the motor is properly protected.
C. Operate above power frequency
This drive can provide 0Hz~600Hz output frequency. If the user need to
run the motor above rated frequency, please consider the affordability of
mechanical devices.
D. The mechanical device resonance
The drive system may encounter mechanical resonance with the load when
operating within certain band of output frequency. Skip frequencies have
been set to avoid it.
E. Motor heat and noise
The output voltage is in PWM wave with some harmonics. Therefore,
temperature rise, noise and vibration of motor are higher than 50Hz.
F. Varistor in the output side and capacitors used to improve the
power factor

SVF-MNSeriesFrequencyInverterOperationManual Chapter1SafetyandNotes
7
Don't connect any varistor or capacitor to the output terminals of the drive,
because the drive's output voltage waveform is PWM, otherwise tripping
or damaging of components may occur; in addition, don't install circuit
breaker or contactor at the output side of the drive.
G. Circuit breakers connected to the input/output of the drive
If contactor is connected between the input power supply and the motor,
Please don’t use contactor to control drive start-stop. If it must be done,
interval time should not less than one-hour. If frequently charging and
discharging, the life of the internal capacitance of the drive will be reduced.
If circuit breaker or contactor needs to be connected between output side
of the drive and the motor, be sure to operate these circuit breakers or
contactor when the drive has no output, to avoid damaging of the drive.
H. Using outside the range of rated voltage
The drive is unsuitable to be used out of the specified range of operation
voltage; otherwise, it may be damaged. If need, please use suitable voltage
regulation device.
I. Change from 3-phase to 2-phase
It is not recommended to change the drive from 3-phase input to 2-phase
input. Otherwise it will lead to failure or damaged.
J. Protection against lightning strike
There are transient surge suppressors inside the Drive which protects it
against lighting strike. Department for frequent thunder and lightning,
users should install the drive front-end protection.
K. Derating due to altitude
Derating must be considered when the drive is installed at high altitude,
greater than 1000m. Because of the thin air, the cooling effect of drive is
deteriorated. Please contact our technical advice in this case.
L. Special usage

Chapter 1 Safety and Notes SVF-MN Series Frequency Inverter Operation Manual
8
If users need the wiring diagram, such as common DC bus, without in the
manual, Please consult our company.
M. Disposing unwanted drive
The capacitors may explode when they are burnt. Poisonous gas may be
generated when the plastic parts like front covers are burnt. Disposing
method: Please dispose the Drive as industrial waste.
Adaptive motor
1) If the motor isn’t the four-pole squirrel-cage asynchronous
induction motor. Please select the drive According to the rated
current of the motor. If you choose the permanent magnet
synchronous motor, please consult our company.
2) Because the cooling fan of non-inverter motor is coaxial
connection with its rotor shaft connection, if the speed of the
motor is reduced, the cooling effect of the fan is deteriorating, if
the motor may become overheating in the situation, please
change to inverter motor or install another fan.
3) The drive has built-in adaptive motor standard parameters,
According to the actual situation, identify parameters or modify
default of the motor to meet the actual value as far as possible;
otherwise, it will affect the operating results and the protection
of property.
4) Because the cable or the inside motor short circuit can cause
the drive alarm, and even explosion. Therefore, the initial
installing motor and cable must be done insulating short-circuit
test. Note, when doing the test, make sure the drive and the

SVF-MNSeriesFrequencyInverterOperationManual Chapter1SafetyandNotes
9
tested part be completely disconnected.
5) If the wire of the motor is over 50 meters, we advice to add
output smoothing reactor. Otherwise, the motor insulation is
easily damaged.
