Use copper conductors with a minimum cross-section of 1,.5 mm2. Connect the communication buses to the electrical switchgearsswitchgear, in which the VERTEX controllers will be installed as well as to all actuators (luminaires, buttons and sensors).
...
The maximum length of the DALI wiring with a 1,.5 mm2 cross-section is 300 m. If that distance is
exceeded or if wiring with an incorrect cross-section is used, the system may not work correctly.
...
The maximum communication bus length depending on the wire cross-section, according to the DALI standard:
Length | Minimum wire cross-section |
|---|---|
up to 100 m | 0.5 mm2 |
100-150 m | 0.75 mm2 |
150-300 m | 1.5 mm2 |
...
Continuous DALI bus current on the DALI bus:
230 mA* for VERTEX ApC
*180 mA for VERTEX ApC 2.0
Device limits on the DALI bus
