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.
