Reserve Power (CTX100 and CTX670)

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 2-61~2-64). 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 changer is standard on the CTX670 power supply. An optional ABCS battery changer must be used in the CTX100 power supply.
