4) 24V_O = Option
supply
The integrated option card and the sensor/actuator interfaces available on it are sup-
plied by 24V_O.
With PROFIsafe option S11, the complete safety electronics and the safe inputs/outputs
are supplied by 24V_O.
Depending on the application, the 24V_O can be supplied by either 24V_C or 24V_S
(via jumpers at X29), or it can be supplied externally. In this case, note that the entire
option card with the connected sensors and actuators is no longer supplied when
voltage is disconnected. This generally prompts an error message.
Connection of
voltages
Both voltages 24V_C and 24V_S can be connected via terminal X20 with a large line
cross-section and further looped to the next unit as "24 V power bus". The voltages
24V_P and 24V_O should be connected to terminal X29.
DANGER
When using PROFIsafe option S11, please observe the SEW publication "Safe Discon-
nection for MOVIFIT
®
".
Severe or fatal injuries
• When using PROFIsafe option S11, observe the permissible wiring diagrams and
safety conditions in the SEW publication "Safe Disconnection for MOVIFIT
®
".
TIP
For connection examples, refer to section "Power bus connection examples"
(see page 80).
