Goodrive20-UL Series VFD
Safety precautions
-3-
Solid-state motor overload protection is performed when the VFD runs at
150% of FLA.
The VFD does not provide motor over-temperature protection.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the
VFD and avoid physical injury or death. For physical safety, the erector should take some
mechanical protective measurements, such as wearing exposure shoes and working
uniforms.
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the VFD by its cover. The cover may fall off.
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 grounding resistor is less than
10Ω. The conductivity of PE
grounding conductor is the same as that of the phase conductor.
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 running
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 can not be used as "Emergency-stop device".
The VFD can not 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 (see Maintenance and Hardware Fault Diagnose).
Cover the front board before running, otherwise electric shock may occur.
