Connection line
We recommend the following maximum cable lengths for installing a 24 V system:
Cable | Section | Length |
Standard DDC line | 0.22 mm² | 20 m |
J-Y(ST)Y | 0.8 mm² | 45 m |
NYM/NYIF | 1.5 mm² | 136 m |
Transformer/power supply unit
A safety isolating transformer according to EN 61558-2-6 or a switching power supply according to EN 61558-2-16 must always be used.
The dimensioning of the transformer or the switching power supply results from the maximum making capacity of the OEM Actuators.
