Safety Precautions for All Power Controllers

For the precautions for individual products, refer to the Precautions for that product.

Precautions for Safe Use

OMRON constantly strives to improve quality and reliability. Power Controllers, however, use semiconductors, and semiconductors may commonly malfunction or fail. In particular, it may not be possible to ensure safety if the Power Controllers are used outside the rated ranges. Therefore, always use the Power Controllers within the ratings. When using a Power Controller, always design the system to ensure safety and prevent human accidents, fires, and social harm in the event of Power Controller failure. System design must include measures such as system redundancy, measures to prevent fires from spreading, and designs to prevent malfunction.

1. Do not apply voltage or current in excess of the ratings to the terminals of the Power Controller. Doing so may result in failure or burn damage.

2. Do not use the Power Controller with loose terminal screws. Doing so may result in burn damage due to abnormal heat produced by the terminals.

3. Do not block the movement of the air surrounding the Power Controller or heat sink. Abnormal heating of the Power Controller may result in shorting failures of the elements or burn damage.

4. Follow the Precautions for Correct Use when performing wiring or tightening the screws. If the Power Controller is used with the wiring or screw tightening performed improperly, burn damage may occur due to abnormal heat generated when the power is being applied.
