Multiple Transformer Wiring
WARNING
Shock Hazard!
If the use of multiple transformers is necessary, locate them so that they do not allow
simultaneous human contact. Touching both 24 Vac outputs simultaneously on two
electrically connected transformers could result in death or serious injury.
Using a dedicated transformer to power the receiver is seldom necessary and is not
advised. Use it only when the host transformer does not have enough volt-ampere (VA)
capacity to power the receiver (see “Specifications,” p. 47 for receiver power
consumption).
If you are using a dedicated transformer to power the receiver, make sure the grounds
(commons) of the multiple transformers are electrically connected to one another, as
shown in the diagram.
