Rigid or flexible wires with a 0.2 to 1.5 mm² cross-section
can be inserted in the spring-loaded terminal blocks for
the serial connection. If the wires have wire end ferrules
with a plastic collar, the maximum cross-section reduced
to 0.75 mm².
For correct and safe connection, carry out the following
operations:
- Strip back the wires by 8mm as shown below;
- if the cable is rigid the end of the wire can be inserted
easily, whereas with flexible cable it may be easier to
use a long pointed pair of pliers to insert correctly.
- Push the wire completely in and check that it is
anchored by pulling it gently.
- To disconnect the cables, press the corresponding
white indent (ref. C) with a screwdriver and remove
the conductor.
Spring-loaded terminal connections -AB+ and CP
CP occupancy contact input connection
On closing the contact connected to the CP input (ref.
A) the panels are placed into stand-by. If the contact is
open the units are active, if the contact is closed they are
deactivated when a key is pressed the symbol flashes.
- To connect the CP input in more than one PCB,
observe the polarity between external relay contact
and CP contacts as shown in the figure.
