General Structure
When using the interference-free variant “…/xxx-8xx”of the IO module 750-530
in safety related applications, the modules belonging to a safety switching device
shall be combined to form a potential group. Power to the potential group shall be
supplied via a power supply module 750-601 or 750-602 or via filter module
750-626. Either a power supply module or a separation module without power
jumper contacts (750-616) must be connected at the end of the potential group.
