 Use the Auxiliary Switch (AUX SW) output terminals on the
PM-30. If shutting down power to an external device is sufficient,
then connecting to the Auxiliary Switch (AUX SW) terminals on the
PM-30 power module ensures power is cut off when the LoLo alarm
is triggered. This may be the preferred solution if the ROC800
provides critical controls. When the LoLo alarm is triggered and the
ROC800 CPU goes into sleep mode, it cuts power to the Auxiliary
Switch (AUX SW) terminals.
