CAUTION
No overvoltage protection is used when switching inductive loads

• Risk of heavy electromagnetic disturbances and lower contact life when no overvoltage protection is used when switching inductive loads.
• When switching inductive loads (e.g. contactors or electric motors) it is strongly recommended to use suitable overvoltage protection devices to avoid heavy electromagnetic disturbances and to ensure the specified contact life.
