Thank you.

Preface
Thank your so much to adopt the GHS-V8 multi-function IGBT inverter
GHS-V8 series (hereafter referred as GHS-8V).
GHS-V8 series of general-purpose inverters provide V/f and vector
control as standard features with user-friendly operation. They are the
high-end work of modern power electronics and electro-mechanic drive
technology. Please read this instruction before attempting to install,
operate, maintain, or inspect a GHS-V8 inverter. It is recommended to
keep this manual in secure and convenient place for any future reference.

■ ＂WARNING＂ or “ CAUTION＂
DANGER！
1. Be sure to turn off the main circuit power before any wiring work is to conduct.
2. Do not touch the circuit or replace any component right after turning off the power
source until the ＂CHARGE＂ LED off because of the high voltage still in the
converter. (LED “Charge＂ lamp indicates that there is still some charge in the
capacitor)
3. Never connect the output terminals U, V, W to AC power supply by mistake.
4. Only authorized personnel should be permitted to perform maintenance, inspections or
parts replacement.
5. Always connect the ground lead E to ground.
6. Never apply high voltage test directly to the components within the inverter. (The
semiconductor devices are vulnerable to high voltage shock).
WARNING
1. Install a (or more) cooling fan to keep the temperature below 45 ℃, when
mounting the inverter in enclosure.
2. Never apply high voltage test directly to the components within the inverter. (The
semiconductor devices are vulnerable to high voltage shock).
3. The CMOS IC on the control board is vulnerable to Electro-Static Discharge. Do not
try to touch the control board.
4. All the parameters of the inverter have been preset at the factory. Do not change the
settings unnecessarily except the case of special application.
CAUTION
1. Prior to installation, operation, and maintenance, read this manual thoroughly and make sure to be
proceeded by qualified professional personnel.
2. Verify if the model types is same as your expectation.
3. Do not install the converter with any damage or missing part.
4. Each inverter shall be attached with QC marking. Do not install the inverter without QC marking.
