WIRING
CAUTION: Do not apply power to the unit until all secondary
wiring is complete, and dip-switches have been set.
The CM-324 can be powered from 12 or 24 volts, AC or DC.
Connect the two Red wires, (which are non-polarity sensitive)
to the power source.
The output is a form C relay. N.O is Blue, N.C. is Violet, and
Common is Green. Selecting the correct output is also
dependant on the operating mode chosen. (See Section 4)
Most applications will utilize the N.O. and Common terminals.
