Chapter 1 Safety Information and Precautions
Safety Definitions: In this manual, safety precautions are divided into the following two categories:
indicates that failure to comply with the notice will result in serious injury or even death
indicates that failure to comply with the notice will result in moderate or minor injury and
equipment damage
Read this manual carefully so that you have a thorough understanding. Installation, commissioning or
maintenance may be performed in conjunction with this chapter. will assume no liability or responsibility
for any injury or loss caused by improper operation.
1.1 Safety Precautions
Use stage
Security Level
Precautions
Before
Installation
DANGER
packing water, parts missing or damaged parts, please do not install!
Packaging logo and physical name does not match, please do not
install!
WARNING
Handling should be light lift, otherwise there is the danger of
damage to equipment!
Do not use damaged drive or missing drive. Risk of injury!
Do not touch the control system components by hand, or there is the
danger of electrostatic damage!
During
Installation
DANGER
Please install the flame-retardant objects such as metal, away from
combustibles, or may cause a fire!
WARNING

Do not allow lead wires or screws to fall into the drive, otherwise the
drive may be damaged!
Install the drive in a place where there is less vibration and direct
sunlight.
Drive placed in airtight cabinet or confined space, please note the
installation of space to ensure the cooling effect.
Wiring
DANGER
You must follow the guidance of this manual and be used by
qualified electrical engineers. Otherwise, unexpected danger may
occur!
There must be a circuit breaker between the drive and the power
supply, otherwise a fire may occur!
Make sure the power supply is in zero-energy state before wiring,
otherwise there is danger of electric shock!
Please follow the standard to the drive properly grounded, otherwise
there is the risk of electric shock!
WARNING

Never connect input power to the drive's output terminals (U, V, W).
Note that the terminal markings, do not take the wrong line!
Otherwise, it will cause damage to the drive!
Never connect the braking resistor directly to the DC bus +, -
terminals. Otherwise, it will cause a fire!
Refer to the manual's recommendations for the wire diameter used.
Otherwise, it may happen accident!
Do not disassemble the connecting cable inside the driver.
Otherwise, the internal of the servo driver may be damaged.

Use stage Security Level Precautions
Before
Power-on
DANGER

Make sure the voltage level of the input power is the same as the
rated voltage of the driver. Check if the wiring position of the power
input terminals (R, S, T) and output terminals (U, V, W) is correct; Of
the external circuit is short-circuited, the connection is tightened, or
cause damage to the drive!
No part of the drive needs to withstand voltage test, the product has
been made before the test. Otherwise, it may cause accident!
WARNING
The driver must be covered before the cover can be powered,
otherwise it may cause electric shock!
All peripheral accessories must be wired according to the instructions
in this manual, and be properly wired in accordance with this manual.
Otherwise, it may cause accident!
After Power-
on
DANGER
Do not open the cover after power on, otherwise there is danger of
electric shock!
If the indicator light does not light after power on, the keyboard does
not display the situation, immediately disconnect the power switch,
do not touch any input and output terminals of the drive, otherwise
there is the risk of electric shock!
WARNING
If parameter identification is required, preclude the possibility of
injury when rotating the motor!
Do not arbitrarily change the drive manufacturer parameters, or it may
cause damage to the device!
During
Operation
DANGER
Do not touch the cooling fan, radiator and discharge resistance to
test the temperature, otherwise it may cause burns!
Non-
professional technicians Do not detect the signal during
operation, otherwise it may cause personal injury or equipment
damage!
WARNING
Drive operation, should avoid something falling into the device,
otherwise it will cause damage to the device!
Do not use the contactor on-off method to control the start and stop
the drive, otherwise it will cause damage to the equipment!
Maintenance
DANGER
Do not live on the equipment repair and maintenance, or there is a
risk of electric shock!
Turn off the input power for 10 minutes before performing
maintenance and repair on the drive, otherwise the residual charge
on the capacitor will cause harm to people!
Do not carry out maintenance and repair on the drive without
personnel who have been professionally trained, otherwise personal
injury or equipment damage will occur!
All pluggable plug-ins must be unplugged in the case of power
failure!
The parameters must be set and checked after replacing the drive.
WARNING
Before performing maintenance work on the drive, make sure that the
motor is disconnected from the drive to prevent the motor from feeding
back power to the drive due to accidental rotation.
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.

VFD500 high performance vector control frequency inverter user manual Chapter 1 Safety information and precautions
- 3-
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.
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 used in a device that may cause a serious accident or damage due to inverter
failure.
