1.2 Precaution
Contactor using
If the contactor is installed on the power input side of the inverter, do not make the contactor frequent on-off
operation. The interval between ON and OFF of the contactor should not be less than one hour. Frequent
charging and discharging will reduce the use of capacitors in the inverter life.
If a contactor is installed between the inverter output terminals (U, V, W) and the motor, make sure that the
inverter is turned on and off when there is no output. Otherwise, the inverter may be damaged.
Lightning impulse protection
Although this series of inverters are equipped with lightning over-current protection device, there is a certain
degree of self-protection for inductive lightning, but for lightning frequent place, customers should also install
lightning protection device in the front of the inverter.
VFD500 high performance vector control frequency inverter user manual Chapter 1 Safety information and precautions
- 3-
Altitude and derating use
In areas above 1000m above sea level, it is necessary to derate the inverter due to poor air quality due to poor
air quality. In this case, please consult our company.
Power input
The inverter power input should not exceed the operating voltage range specified in this manual. If necessary,
use a step-up or step-down device to change the power supply to the specified voltage range.
Do not change the three-phase inverter to two-phase input, otherwise it will cause malfunction or inverter
damage.
Output filtering
When the cable length between the inverter and the motor exceeds 100 meters, it is suggested to use the
output AC reactor to avoid inverter over-current caused by excessive distributed capacitance. Output filter
according to the needs of the field matching.
Inverter output is PWM wave, please do not install the capacitor on the output side to improve the power factor
or lightning varistor, etc., otherwise it may easily lead to inverter instantaneous overcurrent or even damage the
inverter.
About motor heat and noise
Because the inverter output voltage is PWM wave, contains a certain degree of harmonics, so the motor
temperature rise, noise and vibration compared with the same frequency operation will be slightly increased.
Disposal
Electrolytic capacitors on the main circuit and electrolytic capacitors on the printed circuit board may explode
when incinerated, and poisonous gases are generated when plastic parts are burned. Please dispose as
industrial waste.
The scope of application
This product is not designed and manufactured for use on equipment where life is at stake. To use this product
on a mobile, medical, aerospace, nuclear or other special purpose device, please contact our company For more
information.

3.2.4 Cautions for Main Circuit Wiring
（1）Power Supply Wiring
◆ It is forbidden to connect the power cable to the output terminal of the inverter. Otherwise, the internal
components of the inverter will be damaged.
◆ In order to provide input side overcurrent protection and power outage overhaul convenience, the inverter should
be connected to the power supply through circuit breakers and contactors.
◆ Please confirm the power phase, the voltage is consistent with the product nameplate, do not match may result
in damage to the inverter.
（2）DC wiring
◆ Do not connect the braking resistor directly to +, -, which may cause the inverter to be damaged or
even fire.
◆ When using the external brake unit, pay attention to +, - can not be reversed, otherwise it will cause
damage to the inverter and brake unit or even cause a fire.
（3）Motor Wiring
◆It is forbidden to short circuit or ground the inverter output terminal, otherwise the internal components
of the inverter will be damaged.

- 15-
◆Avoid short circuit the output cables or with the inverter enclosure, otherwise there exists the danger of
electric shock.
◆It is forbidden to connect the output terminal of the inverter to the capacitor or LC/RC noise filter with
phase lead, otherwise, the internal components of the inverter may be damaged.
◆When contactor is installed between the inverter and the motor, it is forbidden to switch on/off the
contactor during the running of the inverter, otherwise, there will be large current flowing into the
inverter, triggering the inverter protection action.
◆Length of cable between the inverter and motor
If the cable between the inverter and the motor is too long, the higher harmonic leakage current of the
output end will produce by adverse impact on the inverter and the peripheral devices. It is suggested
that when the motor cable is longer than 100m, output AC reactor be installed. Refer to the following
table for the carrier frequency setting.

3.3EMCquestion and solution
The working principle of the inverter determines that it will certainly produce electromagnetic interference,
affecting and interfering with other equipment. In the meantime, the frequency converter usually works under the
industrial environment with very strong noise,its internal weak signal is also easily disturbed. For safe and
trouble-free operation of the frequency converter, as well as the normal and orderly operation of other equipment,
install the equipment according to the following rules.。
Install the input noise filter,the filter to the inverter input power supply side of the wiring should be as short
as possible.
Filter shell and the installation of the cabinet should be a large area of reliable connection, in order to
reduce the noise current loop impedance.
The wiring distance between inverter and motor should be as short as possible. The motor cable adopts
4-core cable. One end of the ground wire is grounded at the inverter side and the other end is connected
with the motor case. The motor cable is sheathed into the metal pipe.
Input power line and output motor line should be far away from each other.
Easily affected equipment and signal lines should be installed away from the inverter.
The key signal cable should use shielded cable. It is suggested that the shielded cable layer should be
grounded by 360 degree grounding method and set in the metal pipe. As far as possible from the inverter
input power cable and output motor cable, if the signal cable must cross the input power cable or output
motor cable, the two should be orthogonal.
When using the analog voltage and current signals for remote frequency setting, double-stranded,
shielded and shielded cables should be used, and the shield should be connected to the grounding
terminal PE of the inverter. The longest signal cable should not exceed 50 meters.
The control circuit terminals T1A / T1B / T1C, T2A / T2B / T2C and other control circuit terminals should be
separated wiring.
It is forbidden to short-circuit the shield with other signal lines and equipment.
When connecting the inductive load device (magnetic contactor, relay, solenoid valve, etc.) to the inverter,
be sure to use the surge suppressor on the load device coil.
Correct and reliable grounding is safe and reliable operation of the foundation:
(1) Inverter will generate leakage current, the greater the carrier frequency, the greater the leakage current.
Inverter leakage current greater than 3.5mA, the size of the leakage current by the conditions of use, in order to
ensure safety, inverter and motor must be grounded;
(2) Grounding resistance should be less than 10 ohms. Grounding cable diameter requirement, refer to the
same type of input and output cables half of the cross-sectional area selection;
(3) Do not share the ground wire with welding machines and other power equipment;
(4) When using more than two inverters, do not make the ground wire loop.。

Frequency converter to motor cable length and carrier frequency to maintain the appropriate
relationship
When the cable between the inverter and the motor is long, due to the influence of distributed capacitance, it is easy
to produce electrical resonance, thus generating a large current so that the inverter over-current protection. It is
