Goodrive20 Series VFD
Safety precautions
-3-
Install away from children and other public places.
The leakage current of the VFD may be above 3.5mA during operation. Ground with proper
techniques and ensure the grou
nding resistor is less than 10Ω. The conductivity of PE
grounding conductor is the same as that of the phase conductor. For models higher than
30kW, the cross sectional area of the PE grounding conductor can be slightly less than the
recommended area.
R, S and T are the input terminals of the power supply, while U, V and W are the motor
terminals. Please connect the input power cables and motor cables with proper techniques;
otherwise, the damage to the VFD may occur.
1.3.2 Commissioning and operation
Disconnect all power supplies applied to the VFD before the 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 except for the 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 break the motor suddenly. A mechanical
braking device should be provided.
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.
Cover the front board before running; otherwise, electric shock may occur.
1.3.3 Maintenance and component replacement
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
