An external DC power supply can power the SmartTrol. The supply must provide 12-27
VDC and at least 250 mA of current. Connect the positive side (+DC) of the supply to
terminal 14 and the negative (or ground) side to terminal 12. Units Powered by DC voltage
do not have an isolated voltage on terminals 15 and 16.
