China 1kw Frequency Converter for Electric Motor 60Hz 50Hz

Do not install this equipment in an explosive gas atmosphere, or there will be explosion hazards.
only qualified 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 confirmed with the national electric safety regulation and other electric code.
After power off, do not touch internal circuit board or any parts inside within 5 minutes after keypad display went off. Any internal operation must be after making sure of discharge off 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 L1, 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 fire 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 after start the driver, confirm 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.
