Wiring Notes:
• Use a wire connector to attach one
#18 AWG wire for Common (terminal
1) and one #18 AWG wire for 24 V
(terminal 2) from the Class 2/PELV
link to the control. Two #12 AWG
wires cannot both be terminated at
the control station connector.
Maximum wire length from link to
control is 8 feet (2.5 m).
• Only connect the Drain/Shield wire
(bare copper) to terminal ‘D’, in
Softswitch128 panels. Maintain the
shield throughout the link but do not
allow it to touch ground (earth) or
wallstation circuitry.
