Note: Unless otherwise specified, the "**kW" described in this manual refers to
the power of the HD (CT) models. For VFDs of 75, 132, and 500 kW, HD (CT)
and ND (VT) models must be distinguished.
Do not refit the VFD unless authorized; otherwise, fire, electric shock or other
injuries may occur.
The base of the radiator may become hot during running. Do not touch to avoid
serious injury.
The electrical parts and components inside the VFD are electrostatic. Take
measures to prevent electrostatic discharge during related operation.
1.4.1 Delivery and installation
Install the VFD on fire-retardant material and keep the VFD away from
combustible materials.
Connect the optional brake parts (brake resistors, brake units or feedback
units) according to the wiring diagram.
Do not operate on a damaged or incomplete VFD.
Do not touch the VFD with wet items or body parts; otherwise, electric shock
may occur.
Solid State motor overload protection reacts when reaches 150% of FLA.

TD350 Series VFD Safety precautions
-3-
Note:
Select appropriate tools for delivery and installation to ensure a safe and proper running of the
VFD and avoid physical injury or death. To ensure physical safety, the installation staff should
take mechanical protective measures and wear proper personal protective equipment (PPE).
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the VFD by its front cover only as the cover may fall off.
Installation site should be away from children and other public places.
The VFD cannot meet the requirements of low voltage protection in IEC61800-5-1 if the altitude
of installation site is above 2000m.
The VFD should be used in proper environment (see Section 4.2.1 "Installation environment" for
details).
Prevent the screws, cables and other conductive parts from falling into the VFD,
As leakage current of the VFD during running may exceed 3.5mA, ground properly and ensure
the grounding resistance is less than 10Ω. The conductivity of PE grounding conductor is the
same with that of the phase conductor (with the same cross sectional area). For models higher
than 30 kW, the cross sectional area of the PE grounding conductor can be slightly less than the
recommended area.
R, S and T are the power input terminals, and U, V and W are output motor terminals. Connect
the input power cables and motor cables properly; otherwise, damage to the VFD may occur.
1.4.2 Commissioning and running
Disconnect all power sources applied to the VFD before terminal wiring, and wait
for at least the time designated on the VFD after disconnecting the power
sources.
High voltage presents inside the VFD during running. Do not carry out any
operation on the VFD during running except for keypad setting. For products at
voltage levels of 6, the control terminals form extra-low voltage circuits.
Therefore, you need to prevent the control terminals from connecting to
accessible terminals of other devices.
The VFD may start up by itself when P01.21 (restart after power down) is set to 1.
Do not get close to the VFD and motor.
The VFD cannot be used as "Emergency-stop device".
The VFD cannot act as an emergency brake for the motor; it is a must to install
mechanical brake device.
During driving permanent magnet synchronous motor, besides above-mentioned
items, the following work must be done before installation and maintenance.
1. Disconnect all the input power sources including main power and control
power.
2. Ensure the permanent-magnet synchronous motor has been stopped, and
the voltage on output end of the VFD is lower than 36V.

TD350 Series VFD Safety precautions
-4-
3. After the permanent-magnet synchronous motor is stopped, wait for at least
the time designated on the VFD, and ensure the voltage between "+" and "-"
is lower than 36V.
4. During operation, it is a must to ensure the permanent-magnet synchronous
motor cannot run again by the action of an external load; it is recommended
to install effective external brake device or disconnect the direct electrical
connection between permanent-magnet synchronous motor and the VFD.
Note:
Do not switch on or switch off input power sources of the VFD frequently;
For VFDs that have been stored for a long time, set the capacitance and carry out inspection and
pilot run on the VFD before use.
Close the front cover before running; otherwise, electric shock may occur.
1.4.3 Maintenance and component replacement
Only well-trained and qualified professionals are allowed to perform
maintenance, inspection, and component replacement on the VFD.
Disconnect all the power sources applied to the VFD before terminal wiring,
and wait for at least the time designated on the VFD after disconnecting the
power sources.
Take measures to prevent screws, cables and other conductive matters from
falling into the VFD during maintenance and component replacement.
Note:
Use proper torque to tighten the screws.
Keep the VFD and its parts and components away from combustible materials during
maintenance and component replacement.
Do not carry out insulation voltage-endurance test on the VFD, or measure the control circuits of
the VFD with megameter.
Take proper anti-static measures on the VFD and its internal parts during maintenance and
component replacement.
1.4.4 What to do after Scrapping
The heavy metals inside the VFD should be treated as industrial effluent.
When the life cycle ends, the product should enter the recycling system.
Dispose of it separately at an appropriate collection point instead of placing it in
the normal waste stream.

Chapter 3 Product overview
3.1 What this chapter contains
This chapter mainly introduces the operation principles, product features, layouts, nameplates and
model instructions.
3.2 Basic principle
TD350 series VFD is used to control asynchronous AC induction motor and permanent-magnet
synchronous motor. The figure below shows the main circuit diagram of the VFD. The rectifier
converts 3PHAC voltage into DC voltage, and the capacitor bank of the intermediate circuit stabilizes
the DC voltage. The inverter converts DC voltage into the AC voltage used by AC motor. When the
circuit voltage exceeds the maximum limit value, external brake resistor will be connected to
intermediate DC circuit to consume the feedback energy.

Note:
The input current of 0.75–55 kW VFDs is measured at the input voltage of 220V without reactors.
The rated output current is the output current measured at the output voltage of 220V.
Within the allowable input voltage range, the output current/power cannot exceed the rated output
current/power.
Unless otherwise specified, the "**kW" described in this manual refers to the power of the HD (CT)
models. For VFDs of 75, 132, and 500 kW, HD (CT) and ND (VT) models must be distinguished.

Note:
The input current of 1.5–200kW VFDs is measured at the input voltage of 460V without reactors.
The input current of 220–500kW VFDs is measured at the input voltage of 460V with reactors.
The rated output current is the output current measured at the output voltage of 460V.
Within the allowable input voltage range, the output current/power cannot exceed the rated
output current/power.
Unless otherwise specified, the "**kW" described in this manual refers to the power of the HD (CT)
models. For VFDs of 75, 132, and 500 kW, HD (CT) and ND (VT) models must be distinguished.
