The following diagram can be used to determine the cable lengths and wire cross-
sectional areas.
Cable length L
Power P
Permissible cable length L as a function of power P and cross-sectional area of wire as a parameter
P is the decisive power consumption of all actuators connected in parallel. When
operating on AC 24 V, power consumption is in VA; when operating on DC 24 V,
in W.

2.10 Warranty
The engineering data specified in chapter 2.5 Equipment combinations (page 10)
are only guaranteed in connection with the Siemens valves listed. Siemens rejects
any and all warranties in the event that third-party products are used.
When using the actuators in connection with valves of other manufacture, correct
functioning must be ensured by the user, and Siemens will assume no
responsibility.
