Safety precautions
■ Warning sign
DANGER: Indicates that failure to comply with the notice will result in
severe personal injure or even death.
WARNING: Indicates that failure to comply with the notice will result in
moderate personal injury, property damage or equipment damage.
WARNING
◎Do not install or operate any AC Drive that is damaged or with missing parts.
Failing to follow this rule can result in facility damage or severe injury.
◎When installing or handling the AC Drive, please hold the bottom of the
product rather than the case only, to prevent its falling and being damaged.
◎Install the AC Drive on nonflammable material like metal, and keep away from
flammable or explosive object, heat source, and similar environment. Otherwise,
fire may be caused.
◎When AC Drive 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 AC Drive may be
damaged due to extreme high temperature.
◎Before wiring, ensure the AC Drive rated input voltage and phases are
compatible with the input power source, or fire or personal injury may be caused.
◎Never connect the AC power supply to output terminals U, V and W.
Otherwise, the AC Drive will be damaged and the warranty is invalid.
◎Never carry out withstand voltage test to the AC Drive, for example by a
megohmmeter. Otherwise, it may cause damage to the AC Drive.
◎The connecting cable of the main circuit terminal should use an insulating
sleeve.
◎When the cable length between the AC Drive and the motor exceeds 50
meters, an output reactor is recommended to be used.

◎Do not use a circuit breaker to control the start and stop of the AC Drive.
Otherwise, the AC Drive may be damaged.
◎Since the AC Drive makes the motor running speed from low to high in a short
time, please confirm that the motor and equipment are in the allowed running
range before running.
◎Do not touch due to high temperature of the heat sink and braking resistor.
◎The factory parameters of the AC Drive can meet the requirments of most
equipment operation. Under normal circumstances, please do not modify the AC
Drive parameters at will. Even if there is some special applications need to change
the AC Drive parameters, only necessary parameters could be changed.
Otherwise, AC Drive damage may be caused.
◎The PCB board has a CMOS integrated circuit. Do not touch it with your hands,
otherwise, static electricity will damage the PCB board.
DANGER
◎Wiring must be completed by qualified professional electricians, otherwise,
there may be electric shock or damage to the AC Drive.
◎The power must be disconnected during wiring; otherwise, it may cause electric
shock or fire.
◎The grounding terminal should be effectively grounded; otherwise, the outer
casing of the AC Drive may be energized.
◎Do not touch the main circuit terminals, otherwise, it may cause electric shock.
◎Terminals for brake resistor are (+) and PB. Do not wire to other terminals,
otherwise, fire may be caused.
◎It is only allowed to power on the AC Drive after the wiring is finished and its
cover is reinstalled. It is strictly prohibited to remove the cover of AC Drive while
power is on. Otherwise, it may cause electric shock.
◎Before programming the AC Drive with fault auto reset or restart option after
power off, the mechanical device need to be implemented with safety protection
measures first. Otherwise, personal injury will be caused.

◎“ 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
AC Drive control system, otherwise, or personal injury may be caused.
◎When the power is on, there may be electricity in the AC Drive’s terminals
even if it is in stop mode. Do not touch U, V, W terminals and motor connection
terminals, or electrical shock may be caused.
◎Never touch the AC Drive connection terminals when power is on. Otherwise,
it may cause an electrical shock.
◎Only qualified electricians 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 and the
residual voltage does not exist, or wait for at least 10 minutes before carrying out
maintenance or inspection. Otherwise, damage or injury may be caused.
◎Modification to the AC Drive without permission is strictly prohibited,
otherwise, severe injury may be caused. Arbitrarily modification of AC Drive
will result in service warranty invalid.
