(shutdown).
4.10.3

External E-STOP button

Terminals are available at which an external push button (form B contact) can be integrated
into the E-STOP circuit. This contact must be floating, since the electrical circuit is supplied
by a special safety voltage ES/P24 from the SINAMICS DCM DC Converter. These
connections can be omitted if option L57 (Emergency Off) or L59 (Emergency Stop) is
selected.
