Usage cautions
- * Since the NC relay is a polar relay, follow the instructions in the wiring diagram for the (+) (-) connection of the coil. If you make a mistake, it may cause a malfunction or it may not work.
- * In the case of NC relay, there is no problem in operation even if it is used with full wave current, but please note that the suction force will be slightly weakened and the vibration resistance and impact resistance will deteriorate.
