11 Interface for NZM compact circuit-breakers
11.4 Commissioning
SmartWire-DT module IP20 01/20 MN05006001Z-EN www.eaton.com 233
11.3.1 Safety-related applications
For most applications, disconnection in the event of an emergency or the dis-
connection by the opening of the protective doors is also required in addition
to normal operational switching. This must be implemented with suitable
contactor controls.
The circuit-breaker cannot be disconnected via an “emergency switching
off”, i.e. by disconnecting the 24 V supply and is also not normally required.
Without the 24 V power supply, the states of the circuit-breaker are not
changed and no longer displayed. In this case, bus operation is maintained.
11.3.2 Mounting NZM-XSWD-704
The module is fitted on a top-hat rail at a maximum distance of 2 m from the
circuit-breaker. A minimum clearance of 60 mm from the NZM must be
maintained.
11.4 Commissioning
The automatic addressing of all modules in the SmartWire-DT network is per-
formed via the gateway (actuation of the configuration pushbutton on the
gateway) during commissioning. During the addressing process the Smart-
Wire-DT diagnostics LED flashes. Once the addressing process is com-
pleted, the LED indicates a green continuous light.
11.5 Exchange of modules
After replacement of the modules and connection of the voltage the configu-
ration button must be pressed. When this is done, the new module will be
assigned an address.

DANGER
The exchange of the SmartWire-DT module must only be car-
ried out with the supply switched off.
ACHTUNG
The order of the SmartWire-DT units must not be altered.
