The power consumption [W] of the MP/MPL/MFT(2) actuators used is to be added, and the 
corresponding signal conductor lengths are to be read from the diagram. 

Example: 
The following is connected to the MP-Bus: 1 pc. NM24A-MP, 1 pc. SM24A-MP, 1 pc. LMV-D3-
MP and 1 pc. NV24A-MP 

Total power rating 3.5 W + 4 W + 3 W + 3 W = 13.5 W
