Do not refit the VFD unless authorized; otherwise fire, electric shock or other
injury may occur.
The base of the radiator may become hot during running. Do not touch to
avoid hurt.
The electrical parts and components inside the VFD are electrostatic. Take
measurements to avoid electrostatic discharge during related operation.
1.4.1 Delivery and installation
Please install the VFD on fire-retardant material and keep the VFD away from
combustible materials.
Connect the braking optional parts (braking resistors, braking units or
feedback units) according to the wiring diagram.
Do not operate on the VFD if there is any damage or components loss to the
VFD.
Do not touch the VFD with wet items or body, otherwise electric shock may
occur.
Solid State motor overload protection reacts when reaches 150% of FLA.
Drives have no provision for motor over temperature protection.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the VFD and
avoid physical injury or death. For physical safety, the erector should take some mechanical
protective measurements, such as wearing exposure shoes and working uniforms.
Ensure to avoid physical shock or vibration during delivery and installation.

GD310-UL series VFD Safety Precautions
-3-
Install away from children and other public places.
Please use the VFD on appropriate condition (See chapter Installation environment).
Don't allow screws, cables and other conductive items to fall inside the VFD.
The leakage current of the VFD may be above 3.5mA during operation. Proper and reliable
grounding is essential before connecting to power supply. Ground with proper techniques and
ensure the grounding resistor is less than 10Ω. The conductivity of PE grounding conductor is the
same as that of the phase conductor (with the same cross sectional area).
R, S and T are the input terminals of the power supply, while U, V and W are the motor terminals.
Please connect the input power cables and motor cables with proper techniques; otherwise the
damage to the VFD may occur.
1.4.2 Commissioning and running
Disconnect all power supplies applied to the VFD before the terminal wiring
and wait for at least the designated time after disconnecting the power supply.
High voltage is present inside the VFD during running. Do not carry out any
operation except for the keypad setting.
The VFD may start up by itself when P01.21=1. Do not get close to the VFD
and motor.
The VFD cannot be used as “Emergency-stop device”.
The VFD cannot be used to break the motor suddenly. A mechanical braking
device should be provided.
Besides the above items, check to ensure the following ones before the
installation and maintenance during the running of the permanent
synchronous motor:
1. All input power supply is disconnected (including the main power supply and
the control power supply).
2. The permanent magnet synchronous motor has stopped running and
measured to ensure the output voltage of the VFD is less than 36V.
3. The waiting time of the permanent magnet synchronous motor after stopping
is no less than the time designated and measure to ensure the voltage between +
and –is less than 36V.
4. Ensure the permanent magnet synchronous motor does not rotate again
because of the external load. It is recommended to install effectively external
braking devices or disconnect the electric wiring between the motor and the VFD
directly.
Note:
Do not switch on or off the input power supply of the VFD frequently.

GD310-UL series VFD Safety Precautions
-4-
For VFDs that have been stored for a long time, check and fix the capacitance and try to run it
again before utilization (see Maintenance and hardware diagnostics).
Cover the front board before running, otherwise electric shock may occur.
1.4.3 Maintenance and replacement of components
Only qualified electricians are allowed to perform the maintenance, inspection,
and components replacement of the VFD.
Disconnect all power supplies to the VFD before the terminal wiring. Wait for
at least the time designated on the VFD after disconnection.
Take measures to avoid screws, cables and other conductive matters to fall
into the VFD during maintenance and component replacement.
Note:
Please select proper torque to tighten screws.
Keep the VFD, parts and components away from combustible materials during maintenance and
component replacement.
Do not carry out any isolation and pressure test on the VFD and do not measure the control
circuit of the VFD by megameter.
Carry out a sound anti-electrostatic protection to the VFD and its internal components during
maintenance and component replacement.
1.4.4 What to do after scrapping
There are heavy metals in the VFD. Deal with it 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.

This chapter mainly describes the basic guidelines during the installation and commissioning
procedures on the VFD, which you may follow to install and commissioning the VFD quickly.
2.2 Unpacking inspection
Check as follows after receiving products:
1. Check whether the packing box is damaged or dampened. If yes, contact local dealers or
INVT offices.
2. Check the model identifier on the exterior surface of the packing box is consistent with the
purchased model. If no, contact local dealers or INVT offices.

exterior surface of the packing box. If no, contact local dealers or INVT offices.
5. Check whether the accessories (including user's manual and control keypad) inside the
packing box are complete. If not, please contact local dealers or INVT offices.
2.3 Application confirmation
Check the machine before beginning to use the VFD:
1. Check the load type to verify that there is no overload of the VFD during work and check that
whether the drive needs to modify the power degree.
2. Check that the actual current of the motor is less than the rated current of the VFD.
3. Check that the control accuracy of the load is the same of the VFD.
4. Check that the incoming supply voltage is correspondent to the rated voltage of the VFD.
5. Check that the communication needs option card or not.
2.4 Environment

1. Check that the ambient temperature of the VFD is below 40°C . If exceeds, derate according
to the detailed information of Appendix B. Additionally, the VFD cannot be used if the ambient
temperature is above 50°C .
Note: For the cabinet VFD, the ambient temperature means the air temperature inside the
cabinet.
2. Check that the ambient temperature of the VFD in actual usage is above -10°C . If not, add
heating facilities.
Note: For the cabinet VFD, the ambient temperature means the air temperature inside the
cabinet.

3 Product Overview
3.1 What this chapter contains
The chapter briefly describes the operation principle, product characteristics, layout, name plate and
type designation information.
3.2 Basic principles
Goodrive310-UL series VFDs are wall or flange mountable devices for controlling asynchronous AC
induction motors and permanent magnet synchronous motors.
The diagram below shows the simplified main circuit diagram of the VFD. The rectifier converts
three-phase AC voltage to DC voltage. The capacitor bank of the intermediate circuit stabilizes the
DC voltage. The converter transforms the DC voltage back to AC voltage for theAC motor. The brake
pipe connects the external braking resistor to the intermediate DC circuit to consume the feedback
energy when the voltage in the circuit exceeds its maximum limit.

Note:
1. The VFDs of 220V (18.5–55kW) and 460V (G-type≥37kW, P-type≥45kW) supports external DC
reactors and external braking units, but it is necessary to remove the copper tag between P1 and (+)
before connecting. DC reactors and external braking units are optional.
2. The VFDs of 220V (≤15kW), 460V (G-type≤30kW, P-type≤37kW) supports external braking
resistors which are optional.
3. The VFDs of 575V supports external DC reactors and external braking units, but it is necessary to

Note:
The input current of VFDs 0.75–55kW is detected when the input voltage is 220V and there are
no DC reactors and input/output reactors.
The rated output current is defined when the output voltage is 220V.
The output current cannot exceed the rated output current and the output power cannot exceed
the rated output power in the voltage range.
