Goodrive18 series two-in-one VFD Safety Precautions
-2-
1.3 Safety guidelines
Only trained and qualified electricians can operate on the device.
Do not perform any wiring, inspection, or component changing when power is
applied. Ensure all input power supplies are disconnected before wiring or
checking, and always wait at least the time designated on the VFD or until the
DC bus voltage is less than 36V. The following table lists the waiting time.
Do not refit the VFD unless authorized; otherwise, fire, electric shock or other
injuries may result.
The heat sink base may become hot during running. Do not touch it;
otherwise, burns may result.
The electronic components inside the VFD are electrostatic sensitive. Take
measurements to avoid electrostatic discharge during related operation.
1.3.1 Delivery and installation
Install the VFD on fire-retardant material and keep the VFD away from
combustible materials.
Do not run a damaged or incomplete VFD.
Do not touch the VFD with wet items or body parts; otherwise, electric
shock may result.
Select appropriate tools for delivery and installation to ensure proper VFD running and
prevent accidents. To ensure physical safety, take mechanical protective measures such
as wearing safety shoes and working uniforms.
Do not carry the VFD only by its front cover as the cover may fall off.
Ensure to avoid physical shock or vibration during delivery and installation.
Install the VFD far away from children and other public places.
Note that the VFD cannot meet the low voltage protection requirements in IEC61800-5-1
if the installation site altitude exceeds 2000 meters.
As leakage current during VFD running may exceed 3.5mA, apply reliable grounding and
ensure ground resistance is less than 10Ω. The PE ground conductor and phase
conductor have equal conductivity capability. For the models of 30kW or higher, the cross
section of the PE ground conductor can be slightly less than the recommended area.
R, S, T/L, and N are the power input terminals, while U1/U2, V1/V2, and W1/W2 are
output terminals for motors. Connect the input power cables and motor cables properly;
otherwise, VFD damage to may result.
