HF
With simultaneous connection of a large number of electronic ballasts, voltage can fall, which can cause individual luminaires not to start. In such circumstances we recommend that the luminaires are split into groups using a contactor that delays the starting point by 1 - 2 seconds.

F
The values for starting current are set in relation to automated fuses with C-characteristics. The number of luminaires on a 16Amp circuit with 16C fuses will then be: (16/Is) * 0.8. Factor 0.8 is used as the safety factor.

LED
LED luminaires can have a starting current that leads to disconnection of fuse circuits. Starting current can be higher than expected in comparison to conventional luminaires. Read more about the starting current for LED luminaires under the section LOAD AND FUSES under technical specification on each LED luminaire.
