Goodrive390L Series Lift-Dedicated VFD
Do not contact the VFD with damp objects or body parts. Otherwise, electric

shock may result.
The installation site must be away from children and other public places. For

details, see section
Connect the optional braking parts (such as braking resistors, braking units

or feedback units) according to the wiring diagrams.
As VFD leakage current caused 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 as that of the phase
conductor (with the same cross sectional area). The minimum size of the
protective earth conductor should comply with local safety regulations for
high protection earth conductor current equipment.
L1/R, L2/S, and L3/T are the power input terminals, while U, V, and W are the

output motor-connection terminals. Connect the input power cables and
motor cables properly; otherwise, the VFD may be damaged.
When the VFD is installed in a confined space (such as cabinet), it is

necessary to provide protective devices (such as fireproof housing, electrical
protective housing, mechanical protective housing, etc.) that meet the IP
rating, and the IP rating shall comply with the relevant IEC standards and
local regulations.
The VFD cannot act as an emergency brake for the motor; it is a must to

install a mechanical braking device.
Do not switch on or switch off the input power supplies of the VFD

frequently.
If the VFD has been stored without use for a long time, perform capacitor

reforming (for details, see section
for the VFD before the reuse.
Close the VFD front cover before running; otherwise, electric shock may

occur.
High voltage presents inside the VFD during running. Do not carry out any

operation on the VFD during running except for keypad setup. The control
