ETC Installation Guide Contact and Demand Response Interfaces Input and Demand Response Interface Wire Terminations The Input and Demand Response Interfaces provide four sets of terminals (“In” and “V out”) for connection to a momentary (Input Interface only) or maintained contact input. Terminals accept 24-12 AWG (0.2 mm -4 mm wire. - Page 4 ETC Installation Guide Contact and Demand Response Interfaces Terminate Wiring Connect Auxiliary 24 VDC An external 24 VDC (Class 2) auxiliary power supply is required to power the interface. Terminate to the interface terminals labeled 24 VDC. Terminals accept 24-12 AWG (0.2-4 mm ) wires (typically a 16 AWG black and red wire pair).
