VCC-X EM1 Expansion Module Outputs
The VCC-X EM1 Expansion Module must be connected to 24
VAC as shown in the wiring diagram below. Please see Table 1 for
correct VA requirements to use when sizing the transformer(s) used
for powering the expansion module.
Also, please note that when wiring the VCC-X EM1 Expansion
Module, its contacts must be wired as wet contacts (connected to
24 VAC).
See Figure 26 below for input wiring.

WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and 24VAC-to-
24VAC. Failure to observe polarity will result in damage to one or more of the
boards. Expansion Modules must be wired in such a way that the expansion
modules and the controller are always powered together. Loss of power to the
expansion module will cause the controller to become inoperative until power is
restored to the expansion module.
