Chapter I. Safety Precaution
Read this user manual before using GoHz frequency converters.
Keep this user manual near the frequency converter for reading at any time.
Careful in transporting the frequency converter to avoid impact.
Do not put the frequency converter on uneven or inclined place.
Do not block the venting holes or slits to keep the frequency converter well-cooling effect, the back of the
frequency converter should keep 10 cm (4 inches) away from the wall.
Double check the frequency converter and power supply specifications are matched and well-wired before
power connection to avoid any careless damage.
Frequency converters have different installations according to different capacities and voltage levels,
choose an appropriate configuration and cable diameter.
Do not overload the frequency converter to prevent the electric shock or cause fires.
Please follow the implementation of electrician laws and regulations.
In case of abnormal phenomenon happens, follow this user manual in troubleshooting or contact the
manufacturer.
Please keep frequency converter clean and do not put heavy objects on top of it.
Prevent any liquids and sundries into the frequency converter, in order to avoid poor contact or short circuit
to cause electric shock or fire.
Better to unplug the power cord in storm, lightning or thunder days.
Avoid placing in direct sunlight, raining or humid place.
Keep it away from the source of ignition and heat to prevent overheat.
Shutdown the power cord during moving or maintaining the frequency converter.

Chapter IV. Installation
Wiring Precaution
Whether the capacity of the frequency converter in accordance with your loads.
Whether the frequency converter damaged during transportation, if so, do not connect it to power source.
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 consideration, well-grounded system also can avoid the power system interferes
equipment 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.
Ground Types:

Chapter VI. Operation Guide
Proper operating procedures allow you to use the frequency converter more smoothly and avoid unnecessary
troubles.
1. Make sure the POWER ON switch is on OFF position.
2. Make sure the switches, rotary buttons, displays are not loosen or damaged.
3. 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.
4. Set the output frequency by "FREQUENCY SET" switch. Note, press OFF/RESET for setting hundreds
frequency (1xx.x).
5. Choose the Low/High Voltage output voltage according to the loads, for ≤150V change 0-150V (low) and
0-300V (high) base on required voltage.
6. Press to POWER ON switch (ON).
7. Connect loads cable and turn on the AC OUTPUT switch to obtain required standard AC power supplies.
8. GoHz 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 trigger warning buzzer.
9. 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.
