注释Inductive loads (contactors, relays etc.) are to be suppressed by suitable circuitry.

* The safety-related data are based on a load of 24 V / 1 A / DC-1 for the enabling paths.
With higher load currents for the enabling paths and other requirement rates nop, the safety-related data vary from the given data and can be provided on request.
