SAFETY INSTRUCTION
Read this user manual thoroughly before installation, operation, maintenance or
inspection of the variable frequency drive (VFD). In this manual, safety instructions
are classified as “WARNING” or “CAUTION”.
WARNING: Indicate a potentially dangerous situation which, if not avoided,
can result in death or serious injury to personnel.
CAUTION: Indicate a potentially dangerous situation which, if not avoided, can
result in minor or moderate injury and damage to equipment. It may also be used for
warning against unsafe practices.
Even items described as ( CAUTION) may result in a vital accident in some
situations. Please follow these important notes:
■Checking Before installation
◎Do not install or operate any VFD that is damaged or has missing parts. Failing to follow
this rule can result in facility damage or severe injury.
■Installation
◎When installing or handling the VFD, please hold the bottom of the product otherwise its case only,
thus prevent its falling and being damaged.
◎Install the VFD on nonflammable material like metal, and keep away from flammable or
explsive object, heat source, and such environment. Otherwise it may cause a fire.
◎Make sure that the mounting environment free of metal dust. Otherwise it may cause damage
to the VFD.
◎When VFDs is installed inside an electrical cabinet or other kind of enclosure, please install
fans or other cooling devices, and keep ventilation well enough to ensure the enclosure
temperature below 40℃, or the VFD may be damaged due to extreme high rise of temperature.

■Wiring
◎Ensure only qualified electrical engineering personnel for wiring work . Otherwise it
can cause an electrical shock or damage to the VFD.
◎Make sure VFD is isolated from power supply by the circuit breaker. Otherwise it may
cause electrical shock or a fire.
◎Make sure that the ground terminal is grounded correctly. Otherwise it may cause
an electrical shock.
◎Do not touch the main circuit terminals, and keep the wiring of VFD main terminals
from contacting to the enclosure, or it can cause electrical shock.
◎Terminals for brake resistor are (+) and PB. Do not wire to other terminals, otherwise
will cause a fire.
◎Before wiring, ensure the VFD’s rated input voltage and phases is compatible to the
input power source, or it can cause a fire or personal injury.
◎Never connect the AC power supply to output terminals U, V and W. Otherwise the
VFD will be damaged and the guarantee is voided.
◎Never carry out withstand voltage test to the VFD, for example by a megohm meter.
Otherwise it may cause damage to the VFD.
◎VFD’s main circuit wiring and control circuit wiring should be separated, or run
vertically from each other. Otherwise it may cause interference to the control signals.
◎Main circuit wiring cable leads should be crimped with cable lugs in insulated sleeve.
◎If the cable length between the VFD and the motor is greater than 50 meters, it is
recommended to use an output reactor to protect the VFD and the motor.

■Operating
◎It is only allowed to power on the VFD after the wirng is finished and its cover is
reinstalled. It is strictly prohibit to remove the cover of VFD while power is on, otherwise
it may cause electric shock.
◎Before programming a VFD with fault auto reset or restart option after power off, the
mechanical device need to be implemented with safety measures first, otherwise it can lead
to personal injury.
◎”STOP/RESET” key may become invalid as a result of some function setting. It is
recommended to install an independent emergency circuit breaker for the VFD control
system, otherwise it may result in personal injury.
◎When the power is on, the VFD’s terminals may have electricity also even if it is in stop
mode. Do not touch U, V, W terminals and motor connection terminals. Otherwise it may
cause an electrical shock.
◎Do not use a magnetic contactor to control the start and stop of the VFD. Otherwise it
may cause the VFD to be damaged.
◎Before starting, please make sure that the motor and mechanical device can be run with
the VFD’s accelerating time setting in their safe range. Otherwise may result in device
damage.
◎Do not touch the heat sink or braking resistor. Otherwise it may cause harmful burns to
the body.
◎Never modify the parameters casually in unnecessary conditions, as the VFD’s default
parameter setting has already meet the requirements of most mechanical devices. Even if
some devices have special requirements, it is only needed to modify some necessary
parameters. Otherwise, it may cause device damage by improper parameter modification.

■Maintenance
◎Never touch the VFD the connection terminals when power is on. Otherwise it may
cause an electrical shock.
◎Only qualified electrical engineering personnal can be authorized to do the jobs of
maintenance, checking, or parts replacement.
◎After the power supply is OFF, make sure the charge LED is OFF , the residual voltage
is not exist, or wait at least 10 minutes, before carrying out maintenance or inspection.
Otherwise it may cause damage or injury.
◎PCB has CMOS integrated circuit parts, never touch with bare hand, or static electricity
may cause damage to the PCB.
■Other
◎Modification to the VFD without permission is strictly prohibited, otherwise can cause
severe injury. Arbitrarily modification of VFD will result in service guarantee voided.

Chapter 2 Installation and Wiring
2.1 Installation
2.1.1 Installation Environment
◎The ambient temperature exerts great influences on the service life of the VFDs
and is not allowed to exceed the specified temperature range (-10℃ to 40℃ ).
◎A VFD is easy to generate large amount of heat during operation. Thus VFDs
should be mounted vertically with screws on the surface of incombustible objects,
with sufficient spaces nearby for heat sinking.
◎VFDs should be mounted in the place without vibration or with vibration of less
than 0.6G, especially away from those kinds or machine such as punch.
◎The inverter should be mounted in locations away from direct sunlight, high
humidity, condensate, corrosive gas, explosive gas, oil dirt, dust, and metal powder
etc.
