6 Electrical installation
Switch the entire machine/system off line!
The machine/system could unintentionally start up while you are connecting the devices.
Ensure that the entire machine/system is disconnected during the electrical installation.
Connect OSSD1 and OSSD2 separately!
You are not allowed to connect OSSD1 and OSSD2 together, otherwise signal safety will
not be ensured.
Ensure that the machine controller processes the two signals separately.
Downstream contactors must be positively guided and monitored.
Only ever connect one downstream switching element to an OSSD!
Each output signal switching device (OSSD) is only allowed to be connected to one
switching element (e.g. relay or contactor). If several switching elements are required, you
must choose a suitable form of contact duplication.
