1.3 Safety guidelines
Only qualified electricians are allowed to operate on the VFD.
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 VFD or until the DC bus voltage is less than 36V.
Below is the table of the waiting time:
VFD model
Minimum waiting time
1PH 220V
0.2kW-2.2kW
5 minutes
3PH 220V
0.2kW-2.2kW
5 minutes
3PH 380V
0.75kW-2.2kW
5 minutes
Do not refit the VFD unauthorizedly; 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 relevant
operation.
1.3.1 Delivery and installation
Install the VFD on fire-retardant material and keep the VFD away from
combustible materials.
Connect the braking optional parts 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.
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.

Goodrive10 Series Mini VFD Safety precautions
-3-
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the VFD by its cover. The cover may fall off.
Install away from children and other public places.
The pick-up current of the VFD may be above 3.5mA during operation. 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.
1.3.2 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 can not be used as “Emergency-stop device”.
The VFD can not be used to break the motor suddenly. A mechanical
braking device should be provided.
Note:
Do not switch on/off the input power supply of the VFD frequently.
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 Fault Diagnose).
Cover the front board before running, otherwise electric shock may occur.
1.3.3 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.

Goodrive10 Series Mini VFD Safety precautions

Note:
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.
1.3.4 Device disposal
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.

3 Installation guidelines
The chapter describes the mechanical installation and electrical installation.
Only qualified electricians are allowed to carry out what described in this
chapter. Please operate as the instructions in chapter 1 "Safety
precautions". Ignoring these may cause physical injury or death or
damage to the devices.
Ensure the power supply of the VFD is disconnected during the
operation. Wait for at least the time designated until the POWER
indicator is off after the disconnection if the power supply is applied.
The installation and design of the VFD should be complied with the
requirement of the local laws and regulations in the installation site. If
the installation infringes the requirement, our company will exempt from
any responsibility. Additionally, if users do not comply with the
suggestion, some damage beyond the assured maintenance range may
occur.
3.1 Mechanical installation

-10°C–+40°C, and the temperature changing rate is less than
0.5°C/minute.
If the ambient temperature of the VFD is above 40°C, derate 1% for
every additional 1°C.
It is not recommended to use the VFD if the ambient temperature is
above 60°C (empty load).
In order to improve the reliability of the device, do not use the VFD if
the ambient temperature changes frequently.
Please provide cooling fan or air conditioner to control the internal
ambient temperature below the required one if the VFD is used in a
close space such as in the control cabinet.
When the temperature is too low, if the VFD needs to restart to run
after a long stop, it is necessary to provide an external heating
device to increase the internal temperature, otherwise damage to

The VFD can be installed in wall mounting (suitable for VFDs of all overall dimensions):
Figure 3-1 Wall mounting
1. Mark the position of the installation hole. See appendix for the position of installation
hole.
2. Mount the screws or bolts onto the designated position.
3. Put the VFD on the wall.
4. Tighten the fixing screws on the wall.

Note:
The fuse, DC reactor, braking resistor, input reactor, input filter, output reactor, output
filter are optional parts. Refer to Appendix C "Optional peripheral accessories" for
detailed information.
Before connecting the braking resistor cable, remove the yellow labels of PB, (+), and (-)
from the terminal blocks. Otherwise, poor connection may occur.

Grounding terminal
Each machine must carry one PE terminal as
standard configuration.
Note:
Do not use asymmetrical motor cables. If there is a symmetrical grounding conductor in
the motor cable besides the conductive shielded layer, ground the grounding conductor
on the VFD end and motor end.
Route the motor cable, input power cable and control cables separately.
“T”terminal can not be wired in 1PH input.
If C3 input filter is selected, C3 input filter is connected in parallel to input end of the VFD.
GD series VFDs cannot share the DC bus with CH series VFDs.
When sharing the DC bus, the VFDs must be the same in power and must be
simultaneously powered on or off.
In shared DC bus running mode, current balance on the VFD input side must be
considered during wiring, and equalizing reactors are recommended to be configured.
3.2.3 Wiring of main circuit terminals
1. Connect the ground wire of the input power cable to the ground terminal (PE) of the VFD,
and connect the 3PH input cable to the terminals R, S, and T, and fasten them up.
2. Connect the ground wire of the motor cable to the ground terminal of the VFD, and
connect the 3PH motor cable to the terminals U, V, and W, and fasten them up.
3. Connect the brake resistor and other accessories that are equipped with cables to the
specified positions.
4. Fasten all the cables outside of the VFD mechanically, if possible.
