Goodrive300 Series VFD Safety precautions
4
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.
• For VFDs that have been stored for a long time, check and fix the capacitance and try to run it
again before utilization (see Chapter 9 "Maintenance and hardware fault 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.
