12.7 TERMINALS - WIRE CONNECTIONS
Figure 31: This control unit utilises WAGO’s CAGE CLAMP®S terminal blocks, allowing for quick and easy connection.
30. 11. 15. Leaflet Number 671710
JUMPERS
- Terminal blocks can be commoned together to increase the number of terminals at the same
potential using push-in jumpers. In these cases the terminals are treated as one conductor.
JUMPER REMOVED
- Insert the operating tool
blade between the jumper and the partition wall
of the dual jumper slots, then lift up the jumper.
PUSH IN TERMINATION - Stripped solid
conductors, fine-stranded conductors with
ferrules, or ultrasonically “bonded” conductors are
simply pushed in until they hit the backstop.
No tool required.
TERMINATION OF FINE-STRANDED
CONDUCTORS
-
Open the clamp by inserting
an operating tool (as shown below) until it clicks
into position. Then insert the conductor and
remove the operating tool to complete the
connection.
CONDUCTOR REMOVAL
-
Insert an operating
tool in to the operating slot to remove the
conductor, just like the original CAGE CLAMP®
terminal blocks.
DOUBLE DECK TERMINAL BLOCK
- Each deck has a different potential (2-conductor), which creates
a space saving on the rail. Decks can be commoned to adjacent terminal blocks and/or the top to the
bottom deck.
EARTH TERMINAL BLOCKS
-
The earth
terminal block (green/yellow) has a direct
electrical connection to the DIN rail, with the
earthing foot (earth connection only).
FUSE TERMINALS - Replaceable cartridge fuses
are housed in quick release fuse terminals.
