Legend for wiring diagrams a) and b)
1.) SIMOCODE-DP input: not connected (NC)
2.) SIMOCODE-DP input for indicating circuit-breaker state "OFF"
3.) SIMOCODE-DP input for indicating circuit-breaker state "ON"
4.) SIMOCODE-DP input for indicating circuit-breaker state "Tripped"
5.) SIMOCODE-DP output: internal 24 V voltage supply for inputs
6.) SIMOCODE-DP input for 230 V AC operating voltage for motorized operating mechanism.
Note: If rated voltages < 230 V are required for motorized operating mechanisms, the relay
outputs of SIMOCODE-DP can be overloaded (max. continuous rated current 5 A). Suitably
powerful auxiliary relays or contactors must be used in such cases. Please refer to the 3VF
circuit-breaker catalogs for other operational voltages of motorized operating mechanisms.
7.) SIMOCODE-DP output: for "ON" command to 3VF motorized operating mechanism
8.) SIMOCODE-DP output: for "OFF" command to 3VF motorized operating mechanism
9.) SIMOCODE-DP output: not connected
10./11.) SIMOCODE-DP output: not connected
12.) SIMOCODE-DP input: for connecting the screen of the 2-wire cable (earth)
13.) SIMOCODE-DP input: for direct connection of a PROFIBUS-DP 2-wire cable

F1.) Back-up fuse for SIMOCODE-DP voltage supply (cf. SIMOCODE-DP manual)
Power consumption at 230 V AC: 5 VA
F2.) Back-up fuse for motorized operating mechanism
Fuse links gl/gA 6 A; quick-response 10 A or 1.6 A miniature circuit-breaker
Use C characteristic.
Rated continuous current 5 A, simultaneity factor of 100 %
HS.) Auxiliary switch for indicating circuit-breaker state
Note: Any of the SIMOCODE-DP inputs and outputs which are not connected can be parameterized
by the customer as required.
