GENERAL
The switchboard cabinet is built-in the unit and located on removal of the lhousing against the large support of the
unit (view from the right).
Cables must always be lead in the back or via the feet via the cable inlets.
Ensure that the cables form a loop before they enter the switchboard cabinet so that the lowest point of the cable
sits below the cable openings of the switchboard cabinet.
NEVER RUN THE CABLES THROUGH THE TOP OF THE SWITCH CABINET:
DATA PRIVACY IP24 WILL THUS BE CANCELLED.
CONNECTION TERMINALS
The supply must be connected to the connection terminals as given on the diagram supplied.
ATTENTION
NEVER CONNECT 230VAC TO THE LOW VOLTAGE BOARD TERMINALS.
THIS WILL INEVITABLY LEAD TO A FAULT IN THE ELECTRONIC CONTROL AND TRANSFORMER.
CONNECTIONS MUST BE MADE ACCORDING TO THE RULES OF THE ART,
IN ACCORDANCE WITH THE CE STANDARDS AND EXECUTED BY A REGISTERED INSTALLER
THEY ARE THEREFORE NEVER OUR RESPONSIBILITY.
COMPONENTS
All components used – except the circuit board (CDH product) - are standard electrical components.
They can be replaced easily thanks to their mounting on DIN rails.
Equivalent types must replace the relays used.
CONNECTION DIAGRAM
Each installation manual and each switchboard cabinet contains a specific connection diagram for the supply and a
connection diagram for options and controls
Diagrams are drawn in quiescent condition
All PCB are equipped with:
−
a fast glass fuse of 6,3 A for transformer supply and 230V exits
−
a slow glass fuse of 200 mA (5x20 mm) on the secondary 24VDC transformer exit.
