Connection example of SOLID-4 with downstream MSI-SR4 Safety Interface
Device
Attention!
If K3 and K4 are installed in the same switching rack as the MSI-SR4, each relay must be
connected via a separate connecting cable with the MSI-SR4. The connecting cables must
be routed in a strong conduit so that mechanical damage is prevented. Also be sure to
follow the MSI-SR4 connection and operating instructions.
