9 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.
