Installation
17.10 Connecting the ZSI input and output contacts
For zone selectivity on the STD protection and/or the earth fault protection:
Connection to downstream circuit breakers:
STD1: selectivity on the Short time delay protection
GF1: selectivity on the earth fault protection
Cmn1: common
Connection to the upstream circuit breaker:
STD2: selectivity on the Short time delay protection
GF2: selectivity on the earth fault protection
Cmn2: common
hw+ air circuit breakers have 6 ZSI terminal blocks enabling the upstream or downstream
circuit breakers to be connected to deploy zone selectivity (ZSI).
