11 Interface for NZM compact circuit-breakers
11.2 Surface mounting
SmartWire-DT module IP20 01/20 MN05006001Z-EN www.eaton.com 231
11.2.4 Control outputs Q0 and Q1
The control outputs for the remote operator are powered using the Smart-
Wire-DT line's supply voltage. These outputs can handle a maximum load of
200 mA. DILA-22 contactors must always be used as the interface to the
NZM remote operator. After a switch command, one output will always be
“1” and one output will always be “0” - please refer to￫ Section
11.8.1.7, "Outputs", page 242 as well.Wiring must be done as shown in
Figure 87.
If the relevant output is actuated, terminal Q0 or Q1 has a voltage of
24 V DC.
The following switch commands are possible:
In addition to the communication signal, the 8 pole SmartWire-DT connecting
cable provides a voltage of 24 V DC to actuate the auxiliary contactors for the
remote operator.

DANGER
If the remote operator is used, switching commands may be
delayed and therefore carried out when unexpected.
This may result in voltages being applied or motors starting at
unexpected moments.
Because of this, make sure to carry out the "Measures for using
the remote operator" ￫ Page 243.
State Permissible command

ON (switch on)
Trip
OFF (switch off)
ACHTUNG
The outputs must only be used to actuate the remote operator.
The remote operator can only be used for normal operational on/
off switching. Any disconnection in the event of a fault must
always be implemented with an undervoltage release.
