Warning
◎Do not install or operate the VFD if it is damaged or has missing parts. Otherwise it may
result in equipment damage or physical injuries.


Installation
Warning
◎Please hold the bottom of VFD when installing or moving it. In case that the VFD is
broken or damaged; only holding the shell is not allowed.
◎Keep the VFD away from heat, inflammable and explosive goods; Install VFD on the
metal or other nonflammable objects.
◎If the VFD is mounted in an electric cabinet or other enclosed objects, fans or other cooling
device should be installed inside the cabinet; Setting ventilation opening to ensure ambient
temperature is below 40℃. Otherwise it may be damaged because of high temperature.



Danger
◎Wiring must be completed by qualified electrical engineers. Otherwise it can cause an
electrical shock or VFD damage.
◎Before wiring, make sure the power supply is de-energized. Otherwise it will cause an
electrical shock or a fire.
◎Make sure the ground terminal is grounded safely and correctly. Otherwise there will
be a risk of electrical shock on the shell of VFD.
◎Do not touch the main circuit terminal, and the main circuit terminals of the VFD are not
allowed to contact the shell. Otherwise it may cause an electrical shock.
◎Braking resistor of the connection terminal is （+）and PB. Do not connect the other terminals;
Otherwise it may cause a fire.

Wiring
Warning
◎Before connecting, make sure the voltage rating and phase number of VFD is conformed
to the input power voltage, phase number; Otherwise it may cause a fire or physical injuries.
◎Never connect the AC input power supply to the output terminals V, U, W of VFD;
Otherwise it will cause damage to the VFD and you are not guaranteed to enjoy the warranty
services.
◎Never conduct a pressure test on VFD；Otherwise it will cause damage to the VFD.
◎The main circuit wiring of the VFD and the control loop wiring should be separated or
vertical crossed, otherwise the control signal will be interfered.
◎The cable connected to the main circuit terminals should be use lugs with isolated casing.
◎If the length of cable between the VFD and the motor is over 50 meters, an output reactor
is recommended so as to protect the VFD and motor.

Operation
Danger
◎Turn on the input AC power after the wiring of VFD is completed and the front cover is
installed. Do not dismantle the front cover when operating; otherwise it will lead to an
electric shock.
◎When VFD is set with the function of fault automatic reset or auto-restart after power
failure, protection measures for equipment system should be taken in advance. Otherwise it
will cause physical injuries.
◎The key “RUN/STOP” may be lose efficacy because some function had been set, a
separate emergency power switch can be installed in the VFD control system; Otherwise it
may cause damage or physical injuries.
◎Though the VFD terminal is in stop state, the terminal is electrified after power on. Do not
touch; otherwise there will be a risk of electric shock.
Warning
◎Do not use the breaker to control the stop/start of AC drive, or it may damage to the AC
drive.
◎Because the acceleration time is short when AC drive makes motor operates from low to
high speed, make sure the motor and mechanical equipment is within the permitted range

before operation,or it will damage the equipment.
◎The temperature of heat sink and braking resistor is high. Please do not touch. Otherwise,
it may cause burns.
◎When leaving factory, the preset parameters of AC drive have met most of the
operational requirements of equipment. If not necessary, do not arbitrarily change the
parameters. Even some devices have some special requirements; you can only modify the
necessary parameters. Otherwise, arbitrary modification may damage the equipment.

Maintenance and Inspection
Danger
◎When power on, do not touch the connection terminals. Otherwise it may cause an
electrical shock.
◎Only qualified electrical engineering personnel can maintain, replace and inspect the SPD.
◎Wait at least 10 minutes after the power failure, or make sure that is no residual voltage
before carry out maintenance and inspection, otherwise it may cause damage.
Note
◎PCB board has CMOS integrated circuit, do not touch, otherwise the static electricity may
damage PCB board.
Others
Danger
◎It is strictly forbidden to transform the VFD, otherwise it may cause casualties. After
arbitrarily changing VFD, will no longer enjoy the warranty service.

1.8 Maintenance
1.8.1 Routine Maintenance
The influence of the ambient temperature, humidity, dust and vibration will cause
the aging of the devices in the AC drive, which may cause potential faults or
reduce the service life of the AC drive. Therefore, it is necessary to carry out
routine and periodic maintenance.
(1) Routine maintenance involves checking:
• Whether the motor sounds abnormally during running
• Whether the motor vibrates excessively during running
• Whether the installation environment of the AC drive changes.
• Whether the AC drive's cooling fan works normally
• Whether the AC drive overheats
(2) Routine cleaning involves:
• Keep the AC drive clean all the time.
• Remove the dust, especially metal powder on the surface of the AC drive, to
prevent
the dust from entering the AC drive.
• Clear the oil stain on the cooling fan of the AC drive.
1.8.2 Periodic Inspection
Perform periodic inspection in places where inspection is difficult.
Periodic inspection involves:
• Check and clean the air duct periodically.
