Safety Precautions

WARNING
Indicates a potentially hazardous situation which, if not avoided, will result in minor or moderate injury, or may result in serious injury or death.
Additionally there may be significant property damage.

Alert Statements

WARNING

Use only appropriate components or devices complying with relevant safety standards corresponding to the required performance level and category. Conformity to requirements of the performance level category must be determined as an entire system. It is recommended to consult a = certification body regarding assessment of conformity to the required safety level.
Serious injury may occur in an accident. Make sure to use the dedicated actuator D40A-A2, and install the switch and actuator at an appropriate distance so that they do not create a gap that provides access to the hazard.
Serious injury may occur in an accident. When complying with safety standards, install the product in accordance with ISO/EN ISO 14119 with due consideration of the risk of the operator deactivating it.
Auxiliary output is NOT a safety output. Do not use the Auxiliary output individually for any safety function. Such incorrect use causes loss of the safety function of the product and its relevant systems.
Serious injury may possibly occur in an accident. Do not put the actuator or magnet close to the switch when the door is opened.
Be sure to inspect the product daily and every 6 months. Otherwise, serious injury may possibly occur due to the system malfunction.
