Precautions when using Verun Tong inverter
When shipping and storage
During the storage period, it is necessary to ensure that the inverter is not subjected to physical shocks and oscillations. It is also necessary to ensure that they are not exposed to rain and are not placed in places where the ambient temperature is too high.
When transferring, please hold the bottom of the body. Holding only the panel has the risk of the main body falling and hurting the foot.
At the time of installation
Please install it on a board of non-flammable materials such as metal. Installed on flammable materials with a risk of fire.
When more than two inverters are installed in the same control cabinet, please set up a cooling fan and keep the air temperature of the air inlet below 40 degrees Celsius. Overheating can cause fires and other incidents.
Before wiring, please admit that the input power supply has been blocked. There is a risk of electric shock and fire.
Ask an electrical engineering professional to do the wiring work. There is a risk of electric shock and fire.
When debugging
The grounding terminal must be firmly grounded. Otherwise, there is a risk of electric shock and fire.
After the emergency stop terminal is connected, be sure to check whether its action is useful. There is a risk of injury, (the responsibility for wiring is borne by the user).
If the inverter is set to restart the function after power failure, please do not approach the mechanical equipment, because the inverter will suddenly restart when the call comes. There is a risk of injury.
Please connect the braking resistor or braking unit according to the wiring diagram. There is a risk of fire.
operation
Before operation, please confirm the scope of use of the motor and machinery again. There is a risk of injury.
The high-voltage discharge at both ends of the braking resistor will increase the temperature, please do not touch the braking resistor. There is a risk of electric shock and burns.
If the inverter is set to start again after power failure, do not approach the mechanical equipment, because the inverter will suddenly restart when the call comes, and there is a risk of injury.
Repair and dismantling
Intercept the power supply of the main circuit, and admit that the CHARGE light-emitting diode is extinguished before maintenance and inspection. There is a residual voltage on the electrolytic capacitor and there is a risk of electric shock.
Non-professional technicians, please do not carry out maintenance and inspection work. There is a risk of electric shock.
