Electrical connections
• The installation must comply with national requirements and European standards (e.g. EN 60335-1/ EN 50165) for electrical safety;
• The phase and neutral must be connected correctly, an error can lead to dangerous situations. In case of non-compliance with the phase-neutral, the controller will operate in manual reset mode at the end of the start-up safety time;
• Check the cable connections carefully before starting the system. An incorrect connection can damage the controller and compromise security;
• Check the grounding of the controller, the metal housing of the burner and the grounding of the main power supply;
• Ensure the distance between the ionization cable and the power cables/ignition cables;
• Use the shortest and straightest ignition cable possible (max length 25kV).
