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 o 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 x them using the relevant screws;
• After completing the wiring, double check all connections then restore the mains.
