Foreword
MD series inverter is a new
generation of high-performance
modular inverter launched by
Shenzhen Inovance Technology Co.,
Ltd, which represents the future
development direction of the inverter.
Unlike traditional inverters, MD series
inverter creates a customized platform
through modular design and flexible
combination of multiple modules of
single series inverter based on
different customer requirements for
functions and performances.
MD series inverter creates three
new concepts in the future inverter
sector:
1. It firstly creates the three-tier
modular structure standard for new
generation of inverter as shown in
Fig.1.
2. It firstly makes the physical
standard for distinguishing the main
modules, such as motor drive, general
function and special function, from the
sub-modules as shown in Fig.2.
3. It leads the new industry trend of
popularizing the vector control
technology.
Such concepts will bring about
profound influences on the inverter
industry.
The modular structure is described as

1.2 Precautions
1.2.1 Motor Insulation Inspection
When the motor is used for the first time,
or when the motor is reused since the
previous use, or when periodical inspection is
performed, the motor insulation inspection
shall be performed so as to avoid damaging of
the inverter due to the insulation failure of the
motor windings. The motor wires must be
disconnected from the inverter during the
insulation inspection. It is recommended to
use the 500V megameter, and the insulating
resistance measured shall be at least 5Mȍ.
1.2.2 Thermal Protection of the Motor
If the ratings of the motor do not match
those of the inverter, especially when the
rated power of the inverter is higher than the
rated power of the motor, the relevant motor
protection parameters in the inverter shall be
adjusted, or thermal relay shall be mounted to
protect the motor.
1.2.3 Running with Frequency higher than
Standard Frequency
This inverter can provide output
frequency of 0Hz to 300Hz. If the user needs
to run the inverter with frequency of more than
50Hz, please take the resistant pressure of
efesotomasyon.com

Chapter 1 Safety and Precautions

the mechanical devices into consideration.
1.2.4 Motor Heat and Noise
Since the output voltage of inverter is
PWM wave and contains certain harmonics,
the temperature rise, noise and vibration of
the motor will be higher than those when it
runs at standard frequency.
1.2.5 Voltage-sensitive Device or Capacitor
Improving Power Factor at the Output Side
Since the inverter output is PWM wave, if
the capacitor for improving the power factor or
varistor for lightning protection is mounted at
the output side, it is easy to cause
instantaneous over current in the inverter,
which may damage the inverter. It is
recommended that such devices shall not be
used.
1.2.6 Switching Devices like Contactors
Used at the Input and Output Ends of
Inverter
If a contactor is installed between the
power supply and the input end of the inverter,
it is not allowed to use the contactor to control
the startup/stop of the inverter. If use of such
contactor is inevitable, it shall be used with
interval of at least one hour. Frequent
charge and discharge will reduce the service
life of the capacitor inside the inverter. If
switching devices like contactor are installed
between the output end of the inverter and the
motor, it shall ensure that the on/off operation
is conducted when the inverter has no output.
Otherwise the modules in the inverter may be
damaged.
1.2.7 Use under voltage rather than rated
voltage
If the MD series inverter is used outside
the allowable working voltage range as
specified in this manual, it is easy to damage
the devices in the inverter. When necessary,
use the corresponding step-up or step-down
instruments to change the voltage.
1.2.8 Change Three-phase Input to
Two-phase Input
It is not allowed to change the MD series
three-phase inverter into two-phase one.
Otherwise, it may cause fault or damage the
inverter.
1.2.9 Lightning Protection
The series inverter has lightning over
current protection device to provide certain
self-protection capacity against the lightning.
In applications where lightning occurs
frequently, the user shall install additional
protection devices at the front-end of the
inverter.
1.2.10 Altitude and Derating Application
In areas with altitude of more than 1,000
meters, the heat dissipation of the inverter
may turn poor due to rare air. Therefore, it
needs to derate the inverter for use. Please
contact our company for technical consulting
in case of such condition.
1.2.11 Certain Special Use
If the user needs to use the inverter with
the methods other than the recommended
wiring diagram in this manual, such as shared
DC bus, please consult our company.
1.2.12 Precautions at the time of Inverter
Disposal
The electrolytic capacitors on the main
circuit and the PCB may explode when they
are burnt. Emission of toxic gas may be
generated when the plastic parts are burnt.
efesotomasyon.com

Chapter 1 Safety and Precautions
-9-
Please dispose the inverter as industrial
wastes.
1.2.13 Adaptable Motor
1) The standard adaptable motor is
four-pole squirrel-cage asynchronous
induction motor. If such motor is not
available, be sure to select adaptable motors
according to the rated current of the motor.
In applications where drive permanent
magnetic synchronous motor is required,
please consult our company;
2) The cooling fan and the rotor shaft of
the non-variable-frequency motor adopt
coaxial connection. When the rotating speed
is reduced, the cooling effect will be reduced.
Therefore, a powerful exhaust fan shall be
installed, or the motor shall be replaced with
variable-frequency motor to avoid the over
heat of the motor.
3) Since the inverter has built-in standard
parameters of the adaptable motors, it is
necessary to perform motor parameter
identification or modify the default values so
as to comply with the actual values as much
as possible, or it may affect the running effect
and protection performance;
The short circuit of the cable or motor
may cause alarm or explosion of the inverter.
Therefore, please conduct insulation and
short circuit test on the newly installed motor
and cable. Such test shall also be conducted
during routine maintenance. Please note
that the inverter and the test part shall be
completely disconnected during the test.
