7.4 Connecting to the potential compensating
system
If required by local regulations, the PRIMECENTER M1 19-inch rack can be
connected to the indoor potential-compensating system via the grounding
screw located at the lower left side of the rack chassis (see photo below). This
grounding only protects from external parasitic voltages and does not replace
the protective conductor in the mains feeders.
