Siemens PM-E F pm DC24V PROFIsafe Installation And Operating Manual page 89

Wiring Diagram
Wire the PM using the special terminal module.
Figure 7-12
Please always use an external fuse for L+ at the PM-E F pp with the following properties to
protect the relay contacts from overload: Circuit-breaker, characteristics B, 10 A.
Relay Output
The two contacts of the relay output are used to switch voltage L+. The switched voltage is
supplied to the external terminal module and to the internal voltage buses P1 and P2. This
results in two connection options that can be used at the same time, if desired:
● One load can be wired directly to the terminal module (K1 in the figure above).
● Electronic modules can be supplied by means of the internal voltage buses P1 and P2.

WARNING
Loads can be connected to these modules in turn (K2, K3, K4 in the figure above).
WARNING
In the event of a cross circuit between 2L+ and DO, the controlled actuator is no longer
switched off. You should always wire the actuators separately, for example, using
sheathed cables or separate cable ducts, in order to prevent any cross-circuits between
2L+ and DO.
