1. Foreword
To fully employ all functions of the inverter, and to ensure the safety of users, please read
through this operating manual in detail. Should you have any further query, please feel free to
contact your local distributor or sales person of GE Power Controls.
Precaution
Inverter is a power electronic device, for safety reason, please take special care for paragraphs
with “WARNING” or “CAUTION” symbol. They are important safety precautions to be aware of
while transporting, installation, operating or examining the inverter. Please following these
precaution to ensure your safety.
WARNING Personnel injury may be resulted by improper operation.
CAUTION The inverter or mechanical system may be damaged by improper operation.
WARNING
lDo not touch the PCB or components on the PCB right after turning off the power before the
charging indicator went off.
lDo not attempt to wire circuitry while power is on. Do not attempt to examine the components
and signals on the PCB while the inverter operating.
lDo not attempt to disassemble or modify internal circuitry, wiring, or components of the
inverter.
lThe grounding terminal of the inverter must be grounded properly with 200V class type III
standard.
CAUTION
lDo not attempt to proceed dielectric strength test to internal components of the inverter. There
are sensitive semiconductor-devices vulnerable to high voltage in the inverter.
lDo not connect the output terminals: T1(U), T2(V), and T3(W) to AC power outlet.
lThe CMOS IC on the primary PCB of the inverter is vulnerable to static electrical charges. Do
not contact the primary PCB of the inverter.
2. Examination before installation
Every GE Power Controls inverter has been fully tested and examined before shipment. Please
carry out following examination procedures after unpacking your inverter.
lCheck to see the model number of the inverter. It should be the one that you ordered.
lCheck to see if there is any damage during the transportation. Do not connect the inverter
to the power supply if there is any sign of damage.
Report to regional sale representative if you find any abnormal condition as mentioned above.

Chapter 1. Safety Precaution
1. Precautions of operation
Before turning ON power
CAUTION
Choose appropriate power source with correct voltage setting as the input voltage
specification of the inverter.
WARNING
Special care must be taken while wiring the primary circuitry panel. The L1 and L2
terminal must be connected to input power source and must not be mistakenly
connected to T1, T2 or T3 terminal. This may damage the inverter when the power is
turned on.
CAUTION
lDo not attempt to transport the inverter by the front of the cover. Securely hold the
inverter by the heat-sink mounting chassis to prevent the inverter from falling, this
may cause personnel injury or damage to the inverter itself.
lInstall the inverter onto a firm metal base plate or another non-flammable type
material. Do not install the inverter onto or nearby any flammable material.
lAn additional cooling fan may need to be installed if several inverters are installed
into one control panel. The inside temperature inside an enclosed panel should be
below 40 degrees to avoid overheating.
lTurn off the power supply before proceeding to remove or perform any work on any
panel. Carry out installation procedures according to instructions given in order to
avoid a situation resulting in an operational malfunction.
lSuitable for use on a circuit capable of delivering not more than 5000 RMS
symmetrical amperes. 240 Volts maximum.
lThis product is not provided with over speed protection.
lOnly intended for use in a pollution degree 2 macro environment or equivalent
When power is applied
WARNING
Do not attempt to install or remove connector of inverter when the power supply is
turned on. Otherwise, the inverter may be damaged due to the surge peak caused by
the insertion or removal of power.

Under Operation
WARNING
Do not use a separate device to switch ON or OFF motor during operation. Otherwise,
the inverter may experience an over-current breakdown.
WARNING
lDo not remove the front cover of the inverter when the power is ON to avoid
personnel injury caused by electrical shock.
lWhen the automatic restart function is enabled, the motor and machinery will be
restarted automatically.
CAUTION
lDo not touch the heat-sink base.
lThe inverter can be easily operated from low-speed to high-speed range. Please
reconfirm the operating range of motor and machinery.
lDo not examining the signals on the PCB of the inverter when it is under operation.
lAll inverter had been properly adjusted before delivery.
CAUTION
Do not proceed with disassemble or examination procedure before ensuring that the
power is off and the Power LED extinguished.
When examination and maintenance
CAUTION
Inverter environment should be within temp: –10OC ~ +40OC, humidity under 95% RH
without condensing.
CAUTION
After the removal of shield sticker, the environment temperature should be
within –10OC ~ +50OC and humidity under 95% RH without condensing. Besides, the
inverter should be free from water dripping or metal dust.

2. Precautions of operation environment
Avoid direct sunlight Keep away from
corrosive gas or liquid
Keep away from oil
grease and gas
Keep away from salty
environment
Keep away where rain or
dripping water may get
into the inverter
Avoid metal dust and
dusty environment
Avoid massive vibration
Avoid heat
Avoid where environment
temperature is too high
Keep away from high
electrical-magnetic wave
or ultra-high wave.
Keep away from
radio-active matter Keep away from
flammable material
oil

Chapter 2. Hardware Instruction and Installation
1. Operation Environment
Theinstallation siteof theinverter isvery important.It relatesdirectly tothe functionalityand the
life span of your inverter. Please check the installation to meet the following requirements:
lMount the unit vertically
lEnvironment temperature: -10OC ~ +50OC
lAvoid placing close to any heating equipment
lAvoid water dripping or humid environment
lAvoid direct sunlight
lAvoid oil or salty corrosive gas
lAvoid contacting corrosive liquid or gas
lPrevent foreign dusts, flocks, or metal scraps from entering interior
lAway from radioactive matter or flammable material
lAvoid electric-magnetic interference (soldering or power machinery)
lAvoid vibration, if vibration can not be avoided, anti-rattler should be installed to reduce it.
lIf the inverter is installed in an enclosed control panel, please remove the shield sticker
located at the top of the inverter. This will allow additional airflow and cooling.
External Fan Placement needs to be over the top of the inverter
lFor proper Installation of the inverter you must place the front side of the inverter facing
front and the top of the inverter in the up direction for better heat dissipation
lInstallation must be compliant to the following requirements.
