Do not refit the inverter unauthorized; otherwise fire, electric shock or other injury
may occur.
The base of the heat sink may become hot during running. Do not touch to avoid hurt.
The electrical parts and components inside the inverter are electrostatic. Take
measurements to avoid electrostatic discharge during relevant operation.
1.4.1 Delivery and installation
Please install the inverter on fire-retardant material and keep the inverter away from
Connect the braking optional parts (braking resistors, braking units or feedback
Do not operate on the inverter if there is any damage or components loss to the
Do not touch the inverter with wet items or body, otherwise electric shock may occur.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the inverter and
avoid physical injury or death. For physical safety, the installer 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 inverter by its cover. The cover may fall off.
Install away from children and other public places.
The inverter cannot meet the requirements of low voltage protection in IEC61800-5-1 if the sea level of
installation site is above 2000m.
Please use the inverter on appropriate condition (See chapter Installation Environment).
Don't allow screws, cables and other conductive items to fall inside the inverter.
The leakage current of the inverter 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 (with the same cross sectional 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 inverter may occur.
1.4.2 Commission and running
Note:
Do not switch on or off the input power supply of the inverter frequently.
For inverters 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.
Safety precautions
combustible materials.
units) according to the wiring diagram.
inverter.
Disconnect all power supplies applied to the inverter before the terminal wiring
and wait for at least the designated time after disconnecting the power supply.
High voltage is present inside the inverter during running. Do not carry out any
operation except for the keypad setting.
The inverter may start up by itself when P01.21=1. Do not get close to the
inverter and motor.
The inverter can not be used as "Emergency-stop device".
The inverter can not be used to break the motor suddenly. A mechanical braking
device should be provided.
