General directions for installation
CONNECTION TO MAINS
The system must be installed according to national rules in force, in particular we recommend to:
• Connect the system to the mains through an
all-pole circuit breaker
which shall have contact separation of at least 3mm in each
pole and shall disconnect all poles simultaneously;
• The
all-pole circuit breaker
shall be placed for easy access and the switch shall remain readily operable.
POWER SUPPLY INSTALLATION
• Remove the terminal side covers by unscrewing the retaining screws;
• Fix the power supply to a DIN bar or directly to the wall using two expansion type screws;
• Switch off the mains using the circuit breaker mentioned above and then make the connections as shown on the installation diagrams;
• Check the connections and secure the wires into the terminals;
• Replace the terminal covers and fix them using the relevant screws;
• After completing the wiring, double check all connections then restore the mains.
CABLE SIZE
Video connections and Audio connections must be wired in twisted pair: pair the video lines (terminals/signals “V1” and “V2”),
pair the audio lines (terminals /signals “1” and “2”).
IMPORTANT NOTE: SOLID COPPER CABLES MUST BE USED. COPPER COATED STEEL (CCS) AND COPPER COATED
ALUMINIUM (CCA) CAN NOT BE USED ON THE SYSTEM.
