Standard DALI ballasts draw approximately 2 mA each, but older or specialized luminaires can consume up to 4 mA to 6 mA. If the combined draw of the 64 connected devices exceeds 130 mA, communication errors and ballast dropout will occur. If external DALI power supply units (PSUs) are integrated to support higher current demands, the internal DALI supply of the KL6811 must be explicitly deactivated in the controller's register settings to prevent bus instability or hardware failure.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eTo maintain signal integrity over maximum physical runs (up to 300 meters), standard 1.5 mm2 copper conductors must be used for DALI routing. DALI signals are not SELV-compliant and are frequently run in the same multi-conductor cable jacket as the 230 V AC supply. Ensure that the shielding configuration of your network isolates the 1200-baud DALI data path from high-frequency transient spikes generated by variable frequency drives or high-power motor switchgear residing on the same physical cable trays.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 15px; margin-bottom: 1.5rem;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c; display: block; margin-bottom: 0.5rem;\"\u003eCRITICAL WARNING\u003c\/strong\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0;\"\u003eDisconnect all physical power supplies from the K-bus, power contacts, and adjacent field terminals before mounting, removing, or wiring the KL6811.
