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 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.
