The Aim of Anti-tip Components and Precautions

The anti-tip components are necessary for meeting the requirements of IEC60950-1, the international
standard for safety.

The aim of these components is to prevent the products, which are heavy in weight, from toppling as a
result of people running into or leaning onto the products, which can lead to serious accidents such as
persons becoming trapped under the product. (U.S.: UL60950-1, Europe: EN60950-1)

Therefore, removal of such components must always be with the consent of the customer.

Do not remove them at your own judgment.
