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

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.

▓Precautions for peripheral applications:
Power source:
zMake sure the voltage applied is correct to avoid damaging
the inverter.
zA molded-case circuit breaker must be installed between
the AC source and the inverter.
Molded-case circuit breaker:
zUse a molded-case circuit breaker that conforms to the
rated voltage and current of the inverter to control the
power ON/OFF and protect the inverter.
zDo not use the inverter as the switch for run/stop switching.
Leakage breaker:
zInstall a leakage breaker to prevent error operation caused
by electric leakage and to protect operators.
Magnetic contactor:
zNormal operations do not need a magnetic contactor. But a
contactor has to be installed when performing functions
such as external control and auto restart after power
failure, or when using brake controller.
zDo not use the magnetic contactor as the run/stop switch
of the inverter.
Reactor for power improvement:
zWhen inverters below 200V/400V 15KW are supplied with
high capacity (above 600KVA) power source, a reactor
can be connected to improve the power performance.
Input noise filter:
zA filter must be installed when there are inductive load
around the inverter.
Inverter:
zInput power terminals L1, L2, and L3 can be used in any
sequence regardless of phases.
zOutput terminals T1, T2, and T3 are connected to U, V,
and W terminals of the motor. If the motor is reversed while
the inverter is forward, just swap any two terminals of T1,
T2, and T3.
zTo avoid damaging the inverter, do not connect the input
