Goodrive3000 series medium voltage VFD
Safety precautions
-2-
Hazardous voltage is present at the motor cable connection terminals on the VFD
only if the VFD is powered on, regardless of whether the motor is running or not.
Hazardous DC voltage of higher than 1600V is present at the DC bus terminals (+)
and (-).
Hazardous voltage may be present at relay output terminals. The voltage class is
dependent on external circuit.
Do not refit the VFD unless authorized; otherwise fire, electric shock or other injury may
result.
Anyone wearing or implanted with electronic medical devices should stay away from
VFDs, motors, or power cords during power-up, because the presence of magnetic
fields may interfere with the proper operation of medical devices.
The electrical parts and components inside the VFD are electrostatic sensitive. Take
measurements to prevent electrostatic discharge when performing related operations.
1.3.2 Grounding
Ensure the good grounding of the VFD, motor and related equipment to effectively
reduce the VFD electromagnetic radiation, and guarantee personnel safety under any
conditions.
Ensure the grounding cable diameters meet safety requirements.
When multiple cabinets are connected, each cabinet must be independently grounded.
To reduce electromagnetic radiation, it is recommended to use shielded cables, use
360-degree high-frequency loop connection, and connect the shielding wire directly to
the PE to meet safety requirements.
The cross-sectional area of grounding wire must meet the safety requirements.
When the working leakage current of the VFD is greater than 3.5mA (DC) or 10mA
(AC), independent grounding must be used to ensure personnel safety.
1.3.3 Delivery and installation
Do not move the VFD by yourself since it is heavy. Do not move it upside down.
Ensure there is sufficient heat dissipation space for the equipment after installation.
Do not fix the VFD by riveting or welding.
Do not tilt the VFD during installation, otherwise it is easy to tip over.
1.3.4 Run
Before starting the VFD, make sure the connected motor and auxiliary devices meet the
speed requirements for running the VFD. By adjusting the VFD, the connected motor
can run in the speed ranges higher than power frequency and lower than power
frequency.
Do not enable the automatic fault reset function if there may be a dangerous situation.
This function can enable the VFD to keep running even if the VFD has a fault.
1.3.5 Maintenance and component replacement
During maintenance and component replacement, take measures to prevent screws,
cables and other conductive matters from falling into the internal of the Goodrive3000
series products.
