Precautions
The Nexus hardware is designed to be in environments that have a temperature range of 0-60°C
(non-condensing atmosphere). Installing in an environment outside of these parameters will short-
en the life span of the hardware.
Touch-Plate recommends the use of 18 to 22 AWG wire for low voltage wiring of contact closure
products, 18 AWG wire for all 24V power connections, and 16 AWG wire for 2-wire Smart Switch
Stations.
All 120VAC wiring must use wire as specified by National Electric Code for load size and wire length.
Compatible Hardware
• Digital Control Stations
• 2-Wire Stations (Mystique and Ultra Series)
• 5-Wire Stations (Mystique and Ultra Series)
• Contact Closure Control Stations via Smart Control Bridge or on board inputs
• Panel Products (Solare, Soluxe, Calypso, and ZoneZ Series)
