OMX-WCI Addressing
ADDRESS
Contact Closure Wiring
• Connect the desired input(s) and common wires to the
switch provided by others.
• Cap off unused input wires.
Low-Voltage PELV (Class 2: USA) Wiring
Use low-voltage PELV (Class 2: USA) wiring to daisy-
chain the OMX-WCI to the processor panel.
• Use two 2.5 mm
2
(#12 AWG) conductors for common
(terminal 1) and 24 V
(terminal 2). These will not fit
into terminals; see opposite for connection details.
• Use one shielded, twisted pair 1.0 mm
2
(#18 AWG) wires
for data link (terminals 3 and 4).
• Connect drain/shield as shown opposite.
- Do not connect ground/earth to OMX-WCI.
- Connect the bare drain wires and cut off the outside
shield.
• Make connections inside the wallbox, in a switchbox, or
in a junction box with a maximum wire length of 2.5 m
(8 feet) from the link to the OMX-WCI.
