7.2.1
General Structure
When using the interference-free variation ".../8xx-xxx"of the IO module 750-
502 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.
