4.11.8 Maximum line length for 24 VAC supply
Important: For the NVF24-MFT2, dimensional output must be multiplied by
a factor of 2.

Determining maximum line lengths
The dimensional outputs [VA] of all MFT (2) actuators used must be added together
and the corresponding line lengths read from the diagram.
Example: 1 × NM.., 1 × AM.., 1 × AF.. and 1 × NV.. are connected to the MP-Bus.
Total dimensional output: 3 VA + 5 VA + 10 VA + 5 VA = 23 VA

Kabellänge [m]
Cable length vs dimensional output applies to AC supply
(minimum transformer voltage 21.6 VAC)
The following can be read from the family of curves:
– Cable with conductor Ø 0.75 mm² gives: Cable length 25 m
– Cable with conductor Ø 1.0 mm² gives: Cable length 33 m
– Cable with conductor Ø 1.5 mm² gives: Cable length 50 m
– Cable with conductor Ø 2.5 mm² gives: Cable length 85 m

Determining maximum line lengths
Determining maximum line lengths The power consumption values [W] of all
MFT / MFT2 actuators used must be added together and the corresponding line
lengths read from the diagram.
Example: 1 × NM.., 1 × AM.., 1 × AF.. and 1 × NV.. are connected to the MP-Bus.
Total power consumption: 1.3 W + 2.5 W + 6.0 W + 3.0 W = 12.8 W
