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 20~23). The
batteries are kept in a highly-charged state by the power supplys 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 changer is standard on the CTX670 power supply. An optional ABCS battery changer
must be used in the CTX100 power supply.
