Warning
If using console power wires to provide power to a dry contact relay channel, ensure that the
console is positively shut down during installation and service. Failure to remove power may result
in damage to equipment, personal injury or even death.
10. The TS-SCCM sensor wiring must enter the console in IS conduit through a knockout on the IS side of the barrier.
Secure each pair of sensor wires to a single channel on the 4-20mA Analog Input Module. Always use the next
available channel when wiring; for example, if Channels 1 – 3 are being used, Channel 4 must be used next. Pay
close attention to the polarity (+/-) of the wires.
