Installation Manual
7.8 Terminal Wire Connections
7.8.1 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 tools are required.
7.8.2 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.

Removing a Jumper
7.8.3 Conductor Removal
Insert an operating tool in to the operating slot to remove
the conductor, just like the original CAGE CLAMP® terminals blocks.
7.8.4 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.
7.8.5 Jumper Removal
Insert the operating tool blade between the jumper and the partition
wall of the dual jumper slots, then lift up the jumper.
7.8.6 Double Deck Termination 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.
7.8.7 Earth Terminals
The earth terminal block (green/yellow) has a direct electrical
connection to the DIN rail, with the earthing foot (earth connection
only).
7.8.8 Fuse Terminals
Replaceable cartridge fuses are housed in quick release fuse terminals.
7.9 Wiring Diagrams
A series of basic connection wiring diagrams have been provided to
assist on-site wiring. In order to reference the relevant diagrams please
use the code breakdown opposite to determine:
•
Unit size
•
If an electric heater is present
•
If Reverse Cycle DX heating or cooling is present.
The below tables can then be used to reference the required connection
and wiring diagrams.
Example:
Unit onsite has code
B822V/ER/AT-L.
This indicates a size 22 unit with
electric heating and Reverse Cycle DX cooling. Section 9.4 and 9.13
include the basic connection diagram and wiring diagram respectively.
