2009 0 0x0001 ZSI R/W Encoded ZSI, zone-selectivity:
If enabled for releases with ground-fault protec-
tion, ZSI is implemented for both the short-time
delayed short-circuit release and for ground-fault
protection. If enabled for releases without
groundfault protection, ZSI is only implemented
for the short-time delayed short-circuit release.
