Strata CIX General Description
Reserve Power
Two or four customer-supplied 12VDC reserve batteries (80 ampere-hours max.) can be connected
to either system to maintain normal operation during a power failure (see
Tables 11
~
14
). The
batteries are kept in a highly-charged state by the power supply’s battery charger and must be
connected when the system is operating normally. Fully charged batteries must be connected when
normal AC power is available, batteries cannot be connected after/during an actual power failure.
The battery charger is standard on the CIX670 and CIX1200 power supply. An optional ABCS
battery charger must be used in the CIX100 power supply.
