4.1.2.2 Power Supply
The CR1000 is powered by a nominal 12 Vdc source. Acceptable power range is
9.6 to 16 Vdc.
External power connects through the green POWER IN on the face of the
CR1000. The POWER IN connection is internally reverse-polarity protected.
4.1.2.3 Backup Battery
A lithium battery backs up the CR1000 clock, program, and memory in case of
power loss. See Internal Battery
(p. 76).
