techniques and ensure the grounding resistor 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). For models of higher than 30 kW, the cross sectional area of the PE grounding
conductor can be slightly less than the recommended area.
R, S and T are the power supply input terminals, while U, V and W are the output motor
terminals. Connect the input power cables and motor cables correctly; otherwise, damage to
the VFD may occur.
1.4.2 Commissioning and running
Disconnect all power supplies of the VFD before terminal wiring and wait for
at least the designated time after disconnecting the power supply.
High voltage is present inside the VFD during running. Do not carry out any
operation on the VFD except for keypad setting.
The VFD may start up by itself when P01.21=1. Do not get close to the VFD
and motor.
The VFD cannot be used as “Emergency-stop device”.
The VFD cannot be used to brake the motor suddenly. A mechanical brake
device must be installed.
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 pilot run
first before actual application.
Close the front cover before running the VFD; otherwise, electric shock may occur.
1.4.3 Maintenance and component replacement
Only well-trained and qualified professionals are allowed to carry out
maintenance, inspection, and component replacement of the VFD.
Disconnect all power supplies of the VFD before terminal wiring and wait for
at least the designated time after disconnecting the power supply.
Take proper measures to prevent screws, cables and other conductive
objects from falling into the VFD during maintenance and component
replacement.
Note:
Use proper torque to tighten screws.
Keep the VFD and its parts and components away from combustible materials during
maintenance and component replacement.
Do not carry out any insulation voltage-endurance test on the VFD or measure the control
circuit of the VFD by megameter.
