Foreword
To fully employ all functions of this T-verter and to ensure the safety for its users, please read
through this operations manual in detail. Should you have any further questions, please feel free to
contact your local distributor or regional representative.
PLEASE READ AND UNDERSTAND THIS MANUAL BEFORE
OPERATING THIS T-VERTER
The T-verter is a power electronic device. For safety reasons, please read carefully those
paragraphs with “WARNING” or “CAUTION” symbols. They are important safety precautions to be
aware of while transporting, installation, operating or examining the T-verter. Please follow these
precautions to ensure your safety.
WARNING Personnel injury may be resulted by improper operation.
CAUTION The T-verter or mechanical system may be damaged by improper operation.
WARNING
zDo not touch the PCB or components on the PCB right after turning off the power before the
charging indicator went off.
zDo not attempt to wire circuitry while power is on. Do not attempt to examine the components
and signals on the PCB while T-verter operating.
zDo not attempt to disassemble or modify internal circuitry, wiring, or components of the
T-verter.
zThe grounding terminal of the T-verter must be grounded properly (200V class: Ground to 100
Ωor less, 400V class: Ground to 10Ωor less).
zThis is a product of the restricted sales distribution class according to EN61800-3.
In a domestic environment this product may cause radio interference in which case the user
may be required to take adequate measures.
CAUTION
zDo not attempt to perform dielectric strength test to internal components of the T-verter. There
are sensitive semiconductor-devices vulnerable to high voltage in the T-verter.
zDo not connect the output terminals: T1 (U), T2 (V), and T3 (W) to AC power input
zThe CMOS IC on the primary PCB of the T-verter is vulnerable to static electrical charges. Do
not contact the primary PCB of the T-verter.

Precautions for operation
Examination before installation
Every T-verter has been fully tested and examined before shipment. Please carry out the following
examination procedures after unpacking your T-verter.
zCheck to see if the model number of the T-verter matches the model number of the T-verter
that you ordered.
zCheck to see whether any damage occurred to the T-verter during shipment. Do not connect
the T-verter to the power supply if there is any sign of damage.
Before turning ON power
CAUTION
Choose the appropriate power source with correct voltage settings for the input voltage
specification of the T-verter.
WARNING
Special care must be taken while wiring the primary circuitry terminals. The (L1) (L2)
and (L3) terminals must be connected to the input power source and must not be
mistakenly connected to (T1) (T2) or (T3) output terminals. This may damage the
T-verter when the power is turned on.
CAUTION
zDo not attempt to transport the T-verter by the front of the cover. Securely hold the
T-verter by the heat-sink mounting chassis to prevent the T-verter from falling, this
may cause personnel injury or damage to the T-verter itself.
zInstall the T-verter onto a firm metal base plate or another non-flammable type
material. Do not install the T-verter onto or nearby any flammable material.
zAn additional cooling fan may need to be installed if several T-verters are installed
into one control panel. The inside temperature inside an enclosed panel should be
below 40 degrees to avoid overheating.
zTurn 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.
zThis product is not provided with over speed protection.
zOnly intended for use in a pollution degree 2 macro environment or equivalent

When power is applied
WARNING
Do not attempt to install or remove input or out put connectors of T-verter when the
power supply is turned on. Otherwise, the T-verter may be damaged due to the surge
peak caused by the insertion or removal.
Under Operation
WARNING
zDo not use a separate device to switch ON or OFF motor during operation.
Otherwise, the T-verter may experience an over-current breakdown.
zWhen momentary power loss is longer than 2 seconds (the large of horse power,
the longer of time), the inverter does not have enough storage power to control the
circuit; Therefore, when power is regenerated, the operation of the inverter is
based on the setup of Fn_10/16 and the condition of external switch, this is
considered to be「restart」in the following paragraphs.
zWhen the momentary power loss is short, the inverter still has enough storage
power to control the circuit; therefore, when power is regenerated, the inverter will
automatically start operation again depends on the setup of Fn_31/32.
zWhen restart the inverter, the operation of the inverter is based on the setup of
Fn_10 and the condition of external switch (FWD/REV button). Attention: the
restart operation is irrelevant with Fn_31/32/34/35.
(1) When Fn_10=0, the inverter will not start after restart.
(2) When Fn_10=1 and the external switch (FWD/REV button) is OFF, the
inverter will not start after restart.
(3) When Fn_10=1, the external switch (FWD/REV button) is ON, and
Fn16=XXX0, the inverter will start automatically after restart. Attention: Base
on safety reason, please turn off the external switch (FWD/REV button) after
power loss to avoid possible damage to the machine and the human body
after sudden regeneration of power.
WARNING
zDo not remove the front cover of the T-verter when the power is ON to avoid
personnel injury caused by electrical shock.
zWhen the automatic restart function is enabled, the motor and machinery will be
restarted automatically.

CAUTION
zDo not touch the heat-sink base during operation.
zThe T-verter can be easily operated from a low-speed to high-speed range. Please
reconfirm the operating range of motor and the machinery you are controlling.
zDo not examining the signals on the PCB of the T-verter when it is under operation.
zAll T-verters are properly adjusted and set before delivery.
CAUTION
Do not proceed with disassemble or examination procedure before ensuring that the
power is off and the Power LED extinguished.
When performing an examination or maintenance
CAUTION
The environment temperature should be within –10OC ~ +40OC and humidity under
95% RH without condensing. Besides, the T-verter should be free from water dripping
or metal dust.
Others
WARNING
Never modify the product.
Failure to observe this warning can result in an electrical shock or personal injury and
will invalidate the guarantee.

Operational Environment
The installation site of the T-verter is very important. It relates directly to the functionality and the life
span of your T-verter. Please carefully choose the installation site to meet the following
requirements:
zMount the unit vertically
zEnvironment temperature: -10OC ~ +40OC(with cover removed: -10OC ~ +50OC)
zAvoid placing close to any heating equipment
zAvoid water dripping or humid environment
zAvoid direct sunlight
zAvoid oil or salty corrosive gas
zAvoid contacting corrosive liquid or gas
zPrevent foreign dusts, flocks, or metal scraps from entering interior
zAvoid electric-magnetic interference (soldering or power machinery)
zAvoid vibration, if vibration cannot be avoided, an anti-rattle mounting device should be
installed to reduce vibration.
zIf the T-verter is installed in an enclosed control panel, please add additional cooling using an
external fan. This will allow additional airflow and cooling.
zPlacement of external fans should be directly over the top of the T-verter.
zFor proper Installation of the T-verter you must place the front side of the T-verter facing front
and the top of the T-verter in the up direction for better heat dissipation.
zInstallation must be compliant to the following requirements.
