Note:

(1)  Position contact terminal #56-#61 do not pass through the secondary terminal
(2)  Buttons and indicator lights are provided by users themselves
(3)  The secondary wiring of the power supply module is shown in the diagram - the external power supply is input from U1 (+) and U2 (-), and the two output terminals of the

power supply module are connected separately to corresponding secondary wiring terminals #1 (+) and #2 (-)

(4) The contact output functions are optional. The output functions can be selected with reference to "DO Function Setting Table" on Page 54; for default settings, refer to

“Contact Default Setting" on Page 32.

(5)  The above circuit diagrams are the ones when the circuit breaker is in the open position.
(6)  Voltage protection of Phase A, B, C and N is connected to terminals with the maximum voltage of 400V; if above 400V, a voltage module is required
(7)  This wiring diagram includes all the functions. Optional functions are available only after selected and equipped by users
