SOLID-4 connection example
with downstream relay module, MSI-RM2
Warning!
If K4 and K5 are installed in the same switching rack as the MSI-RM2, each relay must be
connected via a separate connecting cable with the MSI-RM2. The connecting cables must
be routed in a strong conduit so that mechanical damage is prevented. Also be sure to
follow the MSI-RM2 connection and operating instructions.
Note!
Additional functions such as Muting or Cycle Control can be implemented with intelligent
safety interfaces of the MSI series from Leuze electronic. For this, see accessories in
Chapter 12.3.
a = EDM feedback circuit
b = Positive-driven relays, spark suppression
