- Shut down power before wiring, check the input voltage before installation.
- Make sure the specification of the cable in accordance with the frequency converter before wiring. The cable diameter should follow the voltage level and capacity of the frequency converter.
- Please refer to electrician wiring regulations, or following the “Cable Diameter Reference” table.
- Avoid sharing the power switch of the frequency converter with other appliances.
- Use O-type wiring terminals, make sure it’s well-wired, tighten screws to avoid poor contact and prevent electric shock.
- Make sure the power source is correct to match single phase or three phase frequency converter.
- For grounding, refer to the next page.
- Make sure all switches on “OFF” status before connecting the frequency converter to power source.
- Make sure the power source, frequency converter and loads are matching before power on.
- Internal semiconductor components are sensitive to static electricity, be careful in touching the metal control panel.
Grounding System
- In addition to safety considerations, a well-grounded system also can avoid the power system from interfering equipment’s normal operation.
- Ground Cable should be separated with Neutral Cable unless special applications.
- Ground Cable should be 8AWG cable at least or the diameter is basically the same.
- Ground Cable is for specified frequency converter only, poor ground will cause interference to other machines.
- Use ground rods in grounding for the best.

Operation Guide
Proper operating procedures allow you to use the frequency converter more smoothly and avoid unnecessary troubles.
- Make sure the POWER ON switch is on OFF position.
- Make sure the switches, rotary buttons, displays are not loosen or damaged.
- Make sure the power supply is matching with the frequency converter specifications (110V, 220V etc.) before turning the input POWER ON switch to ON position.
- Set the output frequency by the “FREQUENCY SET” switch. Note, press OFF/RESET for setting hundreds frequency (1xx.x).
- Choose the Low/High Voltage output voltage according to the loads, for ≤150V change 0-150V (low) and 1-300V (high) base on required voltage.
- Press to POWER ON switch (ON).
- Connect loads cable and turn on the AC OUTPUT switch to obtain required standard AC power supplies.
- Frequency converter has overcurrent (overload), over temperature, short circuit, instantaneous power off protection and warning indicators. In case of above phenomenon happens, the protection circuit cut off output immediately and triggers a warning buzzer.
- Press OFF / RESET switch to cut off the output.
Caution: For 30kVA frequency converter (and above), to switch Low/High voltage, if the frequency converter is connected loads, the frequency converter must be powered off and turn off the output switch before switching the voltage.
