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:
