2.2 Connections and terminal designation
The input terminals ① can be used to establish the connection to the supply voltage. The
"0 V" connection
② is used to supply the internal electronics. The output terminals ③ are
used to connect to the loads to be supplied (see also Chapter Installation (Page 47)).
The operating state of the device can be processed using the group signal contact
④ (for
the function and content rating, see Figure 2-4 Status displays and signaling (Page 16)).
The remote reset (RST) input
④ is used to reset outputs that have automatically been shut
down (function, see Chapter Status displays and signaling (Page 16)).

8 mm of insulation has to be stripped when using conductor end sleeves
Figure 2-2 Terminal data
The terminal location must first be opened for smaller conductor cross-sections and for
flexible conductors without conductor end sleeves. To do this, an appropriate slotted
screwdriver must be inserted into the square slot at the appropriate connection.
We recommend the CRIMPFOX 6 - 1212034 crimping tool to crimp conductor end sleeves. If
the conductor end sleeve is longer than the permissible length of the crimping tool, then the
end sleeve must be crimped in several steps.
Applying pulling and lateral forces to the terminal should be avoided.
