24VAC Power Supply Connection
Use an external fuse on the 24VAC side (secondary side) of the transformer, as shown in the figure below, to protect all
controllers against power line spikes.
The ECLYPSE Controller uses the S terminal as the signal reference point for the data bus (see Common Identification La-
bels for BACnet MS/TP Data Bus Polarity for other Manufacturers).
