• Do not refit the inverter unauthorizedly; otherwise fire, electric shock or other injury may occur.
• Please install the inverter on fire-retardant material and keep the inverter away from combustible
materials.
• Connect the braking optional parts according to the wiring diagram.
• Do not operate the inverter if there is any damage or components loss to the inverter.
• Do not touch the inverter with wet items or body, otherwise electric shock may occur.
• Only qualified electricians are allowed to operate/install the inverter.
• Do not carry out any wiring and inspection or changing components when the power supply is
applied. Ensure all input power supply is disconnected before wiring and checking and always wait for
at least the time designated on the inverter or until the DC bus voltage is less than 36V. Below is the
table of the waiting time:
Inverter Module Minimum Waiting Time
3PH 220V 1HP - 75HP 5 Minutes
3PH 460V 2HP - 100HP 5 Minutes
3PH 575V 25HP - 100HP 5 Minutes
This document is intended as a quick start guide to get familiarity with keypad navigation, changing parameters, and setting
the TD350 drive up for external start/stop and external potentiometer signal. Please note this document is not a substitute for
the TD350 User Manual and it is important that you reference the TD350 user manual before proceeding.

•
The type designation contains information on the VFD. The
user can find the type designation on the type designation
label attached to the VFD or the simple nameplate.
• Check the inverter nameplate to insure that the information
agrees with your order. Also insure that the power available
is rated appropriately for the drive being used.

• Always disconnect the main power supply
before touching any electrical component
associated to the inverter. Several
components can remain charged with high
voltages or remain in movement (fans)
even after the AC power is disconnected
or switched off.
• Wait at least five minutes after turning off
the input power for the complete discharge
of the power capacitors.
• Always connect the grounding point of the
inverter to the protection earth (PE).
POWER CONNECTIONS
BEFORE YOU START
Verify the following wiring setup before you turn on the VFD
for the first time:
• Make sure the line voltage (L1/L2/L3) is NOT connected
to the output terminals (U/V/W) of the VFD.
• Ensure the motor is connected to the drive before apply-
ing power to the VFD.
The fuse, braking resistor, input reactor, input filter, out-
put reactor, output filter are optional parts. Please refer to
Peripheral Optional Parts of TD350 user manual for detailed
information.
Remove the yellow warning labels of PB, (+) and (-) on the
terminals before connecting the braking resistor; otherwise,
poor connection may occur.

• From the Homepage select Menu by pressing function button
• Using the Up/Down keys, scroll down to find Parameter copy/re-
store to default. Follow the screens below:
TECHTOP HIGH-PERFORMANCE VECTOR DRIVES, TD350 QUICK STARTUP GUIDE
STEP 5: Conduct Self Learning (Auto-Tuning)
• Perform motor parameter auto-tuning by selecting
Yes when prompted. Make sure that the motor name-
plate information has been entered correctly in Step
3. Note, Autotuning is only necessary when P00.00 =
0, 1 or 3. When P00.00 = 2 (SVPWM) this step is not
required.
STEP 4: Confirm Rotational Direction
• Test the motor rotating direction by selecting Yes
• Press the key and confirm if the direction is
consistent with expectations. If No is selected the
drive will change the direction by auto setting param-
eter P00.13=1 and the LCD header will display Rev.
