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.

VFD500M vector control frequency inverter user manual Chapter 1 Safety information and precautions
⚫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.
This product is manufactured under strict quality control and should be equipped with a safety device if it is

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.
◆Avoid short circuit the output cables or with the inverter enclosure, otherwise there exists the danger of
electric shock.
13

Chapter 3 Product appearance VFD500M vector control frequency inverter user manual
◆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.

Note:
The multi-function terminal output is open collector output, and the maximum
allowable current is 50mA. When using the internal power supply, if driving an
inductive load, add an absorption circuit, such as an RC snubber circuit or a
freewheeling diode. When adding a freewheeling diode, be sure to confirm the polarity
of the diode, otherwise it will damage the product; For external power supply, connect
the negative terminal of the external power supply to the COM terminal.
