Connection
The electronic trip unit must be supplied with a voltage of 24 V DC. To this end, +24 V DC (positive) must be applied at the X8.3 auxiliary connector
and -24 V DC (negative) at X8.4. The same 24 V DC are connected inside the breaker with option Z=K60 and Z=K62 to the internal relay.
The voltage of 24V ... 230V (depending on the selected undervoltage release) for supplying the undervoltage release is connected at X5.11 and X5.12
- see wiring diagram below.
