2 The output contacts cannot be closed if the On pushbutton is alreadyclosed before the voltage is applied to S12, S22 (also in the event of a linefault at the On pushbutton).A line fault at the On pushbutton which occurs after activation of thedevice is recognized when switching- on takes place again and closingof the output contacts is then a line fault occurs at the On pushbutton after the voltage is alreadypresent at S12, S22 undesired activation will take place, because this linefault does not differ from the normal closing power supply:on when operating voltage presentLED K2:on when supply on K2 LED K3.

8 7 VA, 1 mW .. 7 W in therange 0,1 .. 60 V, 1 .. 300 mA. The contacts also permit the maximumswitching current. However, since the gold plating will be burnt off at thiscurrent level, the device is no longer suitable for switching small loadsafter PE terminal permits operation of the device in IT systems withinsulation monitoring and also serves as a reference point for testing thecontrol voltage. The internal short-circuit protection will be bridged on DCdevices, if the protective ground is connected to terminal or more extension modules BN 5989 or external contactors withpositively-driven contacts may be used to multiply the number of contactsof the Emergency stop Module BD automatic restart:S22 must be connected before S12.
