IMPORTANT
The max. length of a signal cable with 24 Vac supply is 550 ft (170 m).
The max. length of a two-wire, 0 to 10 Vdc signal cable is 1,300 ft (400 m).
The secondary side of the transformer must not be connected to earth
ground.
For detailed information on cable types to be used in accordance to regional
requirements, please refer to the U.S. and European Specifications chapters.
