. c Designing a DALI application Calculating the voltage drop The formula for calculating the voltage drop is as follows: U v Voltage drop in V I Current in A (0.25 A) S Cross section in mm 2 l Cable length in m γ Electrical conductivity in m / (Ω mm 2), for copper cable: 56 m / (Ω mm 2) I NOTICE The maximum current of 250 mA must be used for calculating the voltage drop. Example: DALI circuit with a cable length of 300 m and a cable cross-section of 1.5 mm² Exact result: This example shows that: for a cable length of 300 m the voltage drop along the cable is 1.786 V a further voltage drop of 0.214 V is available for terminal points (contact resistance) Rule of thump: As it is somewhat tricky to calculate the cable length based on the voltage drop the rule of thumb is as follows: If a cross-section of 1.5 mm² is used, the maximum cable length is 300 m. If a smaller cross-section is used the possible cable length is reduced accordingly. I NOTICE Tridonic recommends always using a cable cross-section of 1,5 mm² for DALI control lines.

. c Designing a DALI application Wiring The following points must be considered: Figure: Typical texture of used wires DALI systems are installed using conventional wiring material for line voltage. Two wires are needed for the DALI control circuit. The line voltage and bus line may be routed in the same cable. This corresponds to a 5-core cable (L, N, PE, DA, DA) I NOTICE According to DIN VDE 0100/T520/Part 6, main circuits and associated auxiliary circuits may be laid together even if the auxiliary circuits carry a lower voltage than the main circuits. Make sure to use cable designed to take the maximum operating voltage. Figure: Different polarity of DALI lines There is no need to worry about the polarity of the DALI line. The DALI signal is not SELV. The installation instructions for low voltage therefore apply There are no special network topology requirements (star and mixed networking are permitted) DALI Manual | 08-2013 | en 61 / 93
