Only trained and qualified professionals are allowed to carry out related operations.
Do not perform wiring, inspection or component replacement when power supply is
applied. Ensure all the input power supplies have been disconnected before wiring
or inspection, and wait for at least the time designated on the Goodrive800 Pro
series product or until the DC bus voltage is less than 36V. The minimum waiting
time is listed in the following.
Model
380V
690V
Do not refit the Goodrive800 Pro series product unless authorized; otherwise fire,
electric shock or other injury may result.
The base may become hot when the Goodrive800 Pro series product is running. Do
not touch. Otherwise, you may get burnt.
The electrical parts and components inside the Goodrive800 Pro series product are
electrostatic sensitive. Take measurements to prevent electrostatic discharge when
performing related operations.
Do not install the regenerative rectifier on inflammables. In addition, prevent the
regenerative rectifier from contacting or adhering to inflammables.
Do not run the regenerative rectifier if it is damaged or incomplete.
Do not contact the rectifier unit with damp objects or body parts. Otherwise, electric
shock may result.
Select appropriate tools for regenerative rectifier delivery and installation to ensure
the safe and proper running and avoid physical injury or death. To ensure personal
safety, take mechanical protective measures like wearing safety shoes and working
uniforms.
Protect the regenerative rectifier against physical shock or vibration during the
delivery and installation.
Do not carry the product only by its front cover as the cover may fall off.
The installation site must be away from children and other public places.
Prevent the screws, cables and other conductive parts from falling into the rectifier
unit.
As regenerative rectifier 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 must meet the following requirements:
Power cable conductor
cross-sectional area S (mm
S≤16
16<S≤35
35<S
R, S, and T are the power input terminals, while U, V, and W are the DC bus output
terminals. Connect the input power cables and output busbars properly; otherwise,
the regenerative rectifier may be damaged.
