1.3 Notes for Using FV20
Pay attention to the following issues when using
FV20.
1.3.1 About Motor and Load
Compared to the power frequency operation
FV20 series drives are voltage type variable
frequency drive. The output voltage is in PWM wave
with some harmonics. Therefore, temperature rise,
noise and vibration of motor are higher compared to
the power frequency.

2
2
Low Speed operation with Constant Torque
Driving a common motor at low speed for a long
time, the drive’s rated output torque will be reduced
considering the deterioration of heat dissipation
effect, so a special variable frequency motor is
needed if operation at low speed with constant
torque for a long term.
Motor’s over-temperature protecting threshold
When the motor and driver are matched, the drive
can protect the motor from over-temperature. If the
rated capacity of the driven motor is not in
compliance with the drive, be sure to adjust the
protective threshold or take other protective
measures so that the motor is properly protected.
Operation above 50Hz
When running the motor above 50Hz, there will be
increase in vibration and noise. The rate at which
the torque is available from the motor is inversely
proportional to its increase in running speed.
Ensure that the motor can still provide sufficient
torque to the load.
Lubrication of mechanical devices
Over time, the lubricants in mechanical devices,
such as gear box, geared motor, etc. when running
at low speed, will deteriorate. Frequent
maintenance is recommended.
Braking Torque
Braking torque is developed in the machine when
the drive is hoisting a load down. The drive will trip
when it can not cope with dissipating the
regenerative energy of the load. Therefore, a
braking unit with proper parameters setting in the
drive is required.
The mechanical resonance point of load
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.
Start and stop frequently
The drive should be started and stopped via its
control terminals. It is prohibited to start and stop
the drive directly through input line contactors,
which may damage the drive with frequent
operations.
Insulation of Motors
Before using the drive, the insulation of the motors
must be checked, especially, if it is used for the first
time or if it has been stored for a long time. This is to
reduce the risk of the Drive from being damaged by
the poor insulation of the motor. Wiring diagram is
shown in Fig. 1-1. Please use 500V insulation tester
to measure the insulating resistance. It should not
be less than 5MΩ.
Fig. 1-1 checking the insulation of motor
1.3.2 About Variable Frequency Drive
Varistors or Capacitors Used to Improve the Power
Factor
Considering the drive output PWM pulse wave,
please don't connect any varistor or capacitor to the
output terminals of the drive, otherwise tripping or
damaging of components may occur; as shown in
fig 1.2
M
U
V
W
Fig. 1-2 Capacitors are prohibited to be used.
Circuit breakers connected to the output of VFD
FV20

3
3
If circuit breaker or contactor needs to be
connected between 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.
Using VFD beyond the range of rated voltage
The drive is not suitable to be used out of the
specified range of operation voltage. If needed,
please use suitable voltage regulation device.
Protection from lightning
There is lighting-strike over-current device
inside the Drive which protects it against lighting.
Derating due to altitude
Derating must be considered when the drive is
installed at high altitude, greater than 1000m. This
is because the cooling effect of drive is deteriorated
due to the thin air, as shown in Fig.1-3 that indicates
the relationship between the altitude and rated
current of the driver.
Fig. 1-3 Derating Drive's output current with altitude
1.4 Disposing Unwanted Driver
When disposing the VFD, pay attention to the
following issues：
The electrolytic capacitors in the driver may explode
when they are burnt.
Poisonous gas may be generated when the plastic
parts like front covers are burnt.
Please dispose the drive as industrial waste.

Chapter 3 Installation Environment
In this chapter we introduce the installation environment of VFD
3.1 Installation environment requirements
Please mount the drive vertically inside a well-ventilated location.
When considering mounting environment, the following issues should be taken into account：
Ambient temperature should be within the range of-10℃~40℃. If the temperature is higher than 40 ℃,
the drive should be derated and forced ventilation is required;
Humidity should be lower than 95%,non-condensing
Install in the location where vibration is less than 5.9m/s² (0.6g);
Install in the location free of direct sunlight.
Install in the location free of dust, metal powder.
Install in the location free of corrosive gas or combustible gas.
If there are any special requirements for installation, please contact us for clarifications.
The requirements on mounting space and clearance are shown in Fig. 3-1 and Fig. 3-2.
Fig 3-1 Installation interval (Power below 45kW)
Fig 3-2 Installation interval(Power above 55kW)
When two VFD are mounted and one is on the top of another, an air flow diverting plate should be fixed in
between them as shown in Fig. 3-3.

3.2.1 Configuring device description
Device
Description
Breaker
The capacity of the circuit breaker is generally selected according to 1.5~2 times of the rated current of
the inverter.
Since the output voltage of the inverter is PWM high-frequency pulse voltage, the leakage current is
unavoidable. It is recommended to select the B-type special leakage protector.
Contactor
Easy to control, but frequently open and close of the contactor will cause the inverter to malfunction.
Input Inductor
Improve the impact of power factor and three-phase imbalance on the system.
Suppress the effect of spike current on the input of the inverter.
Reduce external interference
Input filter
Improve the anti-interference ability of the inverter and reduce the external interference of the inverter
Output filter
reduce the external interference of the inverter
Output Inductor
When the cable from the inverter to the motor exceeds 100 meters, it is recommended to install an AC
reactor to suppress harmonic voltage and reduce leakage current.

Chapter 4 Wiring Guide of VFD
In this chapter we introduce the wiring of VFD
Danger
·Wiring can only be done after the drive’s AC power is disconnected, all the LEDs on the operation panel are off
and waiting for at least 10 minutes. Then, you can remove the panel.
·Wiring job can only be done after confirming the charge indicator on the right bottom is off and the voltage
between main circuit power terminals + and - is below DC36V.
·Wire connections can only be done by trained and authorized person
·Check the wiring carefully before connecting emergency stop or safety circuits.
·Check the drive’s voltage level before supplying power to it, otherwise human injuries or equipment damage
may happen.
!
Attention
·Check whether the Variable Speed Drive’s rated input voltage is in compliant with the AC supply voltage before
using.
·Dielectric strength test of the drive has been done in factory, so you need not do it again.
·Refer to chapter 2 on connected braking resistor or braking kit.
·It is prohibited to connect the AC supply cables to the drive’s terminals U, V and W.
·Grounding cables should be copper cables with section area bigger than 3.5mm², and the grounding resistance
should be less than 10Ω.
·There is leakage current inside the drive. The total leakage current is greater than 3.5mA, depending on the
usage conditions. To ensure safety, both the drive and the motor should be grounded, and a leakage current
protector (RCD) should be installed. It is recommended to choose B type RCD and set the leakage current at
300mA.
·The drive should be connected to the AC supply via a circuit breaker or fuse to provide convenience to input
over-current protection and maintainance.
