1 Safety Precautions and Product Model
1.1 Safety Precautions
◇ Do not install this equipment in an explosive gas atmosphere, or there will be explosion
hazards.
◇ Only qualied individuals should proceed with wiring, or there will be electric shock hazards.
Do not conduct any wiring during the system power on to avoid the electric shock.
◇ Do not touch control terminals, internal circuit board and its components, or there will be
electric shock hazard.
◇ Earth terminal must be exactly grounded when using inverter. Grounding must be conrmed
with the national electric safety regulation and other electric code.
◇ After power o, do not touch internal circuit board or any parts inside within 5 minutes after
keypad display went o. Any internal operation must be after making sure of discharge o
with instrument checking to avoid the electric shock.
◇ Do not connect AC power to output terminal (U, V, W) of inverter. The only terminal the AC
power allowed to be connected is R, S, T (or Ll, L2 single-phrase source inverter).
◇ Static electricity on human body can damage MOS device. Do not touch PCB and IGBT
without anti-static measure.
◇ Do not lose screws, spacers and other metallic foreign bodies inside the driver to avoid re
hazard and driver damage.
◇ Do not connect 220V AC power to internal control terminal of the driver, or there will be
serious damage to the driver.
◇ If overcurrent protection occurs aer start the driver, conrm again the external wiring and
then power on and run the driver.
◇ Do not switch off the power to stop the driver. Cut off power source after the motor stops
running.
◇ Do not install the driver in places with direct sunlight.

2 Installation and wiring
Danger
◇ Ensure the power has been cut o before wiring.
Electric chock and re hazard.
◇ Ask electric engineering professionals to conduct wiring.
Electric chock and re hazard.
◇ Earth terminals must be reliable grounded.
(380V class: especially the third grounding)
Electric shock and re hazard.
◇ Check if its action is eective after emergency brake terminal is connected.
Injury risk (wiring responsibility should be beard by users).
◇ Do not touch output terminals directly. The output terminal is connected directly to
motor. There should be no short circuit between output terminals.
Electric shock and short circuit hazard.
◇ Install the terminal cover before power on, and ensure power o when dismantling the
terminal cover.
Electric shock hazard.
◇ Conduct check and maintenance after 5 ～ 8 minutes after power o when internal
residual electricity is discharged completely.
Hazard of residual voltage in electrolytic capacitor.
Cautlon
◇ Check if the voltage of power inlet wire agrees with rated input voltage of VFD.
Injury and re hazard.
◇ Connect brake resistor or brake unit according to wiring diagram.
Fire hazard.
◇ Choose screw driver and wrench with specied torque to fasten terminals.
Fire hazard.
◇ Do not connect the power input wire to output U, V, W terminals.
It will cause internal damage to VFD if load the voltage on output terminals.
◇ Do not dismantle the front panel cover, only the terminal cover needs to be dismantled
when wiring.
It may cause internal damage to VFD.
008
◇ No corrosive gases, vapors, dust or oily dust, no direct sunlight.
◇ No oating dust and metal particle.
◇ Ambient humidity 20% ～ 90% RH.
◇ Vibration less than 5.9m/s2(0.6g).
◇ No electromagnetic interference.
◇ Ambient temperature -10℃ ～ 40℃ . Ensure good ventilation when ambient temperature
exceeds 40℃ .
◇ Use electric cabinet or remote control method in non-standard operation environment
and ensure good ventilation and heat dissipation. The service life of VFD lies in installing
environment and operation condition. But even in standard environment, a long-term
continuous running can guarantee a life of no more than 5 years for electrolytic capacitor
and about 3 years for cooling fan. An update or a thorough maintenance in advance is
recommended.
2.1 Operation Environment
To ensure a good cooling cycle, the VFD must be installed vertically, and keep enough space from
surroundings.
