
Do not use a load which generates surge voltage.
When a surge-generating load such as a relay or solenoid is driven directly, use a product with a built-in surge
absorbing element.

The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes
in the system.

Mount the product in a place that is not exposed to vibration or impact.
Otherwise failure or malfunction can result.

Prevent foreign matter such as remnant of wires from entering the product.
Take proper measures for the remnant not to enter the product in order to prevent failure or malfunction.


Adjustment and Operation

Turn the power on after connecting a load.
Otherwise it can cause excess current causing instantaneous breakage of the product.
