Strata CTX670 Installation

Power Considerations

Power Considerations

Each CTX670 Base and Expansion Cabinet houses a power supply that furnishes power to all of the stations and some of the peripherals that interface with the cabinet (see Table 2-60, “Strata CTX670 Electrical Characteristics” on page 2-47).

Reserve Power

Two or four customer-supplied 12VDC reserve batteries can be connected to the system to maintain normal operation during a power failure (see Table 2-63 on page 2-49and Table 2-60 on page 2-47). The batteries are kept in a highly-charged state by the standard power supply 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.

Underwriters’ Laboratory (UL) and local electrical codes require certain standards for connecting commercial AC and reserve power to the CTX670 system. Table 4-1describes which assemblies may be required to meet UL and local electrical code standards.
