Goodrive350-19 Series VFD for Crane
measures like wearing safety shoes and working uniforms.

Protect the VFD against physical shock or vibration during the delivery and installation.

Do not carry the VFD only by its front cover as the cover may fall off.

The installation site must be away from children and other public places.

Use the VFD in proper environments. (For details, see section 4.2.1 Installation environment.)

Prevent the screws, cables and other conductive parts from falling into the VFD.

As leakage current of the drive 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. The cross-sectional area of the PE grounding conductor for
30kW and higher models can be slightly smaller than the recommended cross-sectional area
value.

R, S, and 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.
1.4.2 Commissioning and running
 Cut off all power supplies connected to the VFD before terminal wiring, and wait
for at least the time designated on the VFD after disconnecting the power
supplies.
 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
terminals of 3PH AC 660V models form extra-low voltage (ELV) 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 is set to 1 (restart after power off).
Do not get close to the VFD and motor.
 The VFD cannot be used as an "Emergency-stop device".
 The product cannot act as an emergency brake for the motor; it is a must to install
a mechanical braking device.
 During driving a permanent magnet SM, besides above-mentioned items, the
following work must be done before installation and maintenance:
a) All input power supplies have been disconnected, including the main power
b) The permanent-magnet SM has been stopped, and the voltage on output
c)
and control power.
end of the VFD is lower than 36V.
After the permanent-magnet SM has stopped, wait for at least the time
designated on the VFD, and ensure the voltage between + and - is lower
than 36V.
