Connecting a Common AC Power Supply
to Several Transmitters
If you are connecting a common 24 VAC power supply to several
transmitters, make sure to connect the same terminal to +Vs and –Vs on
all transmitters. This will avoid a short-circuit through the shared
common line at the controller; see Figure 20 below.
