Description
The dual AC power module provides surge protection for the library power
system and monitors the primary AC input power to determine whether it is
present and of adequate voltage. If the primary AC input fails or drops too low,
the dual AC power module checks the voltage on the secondary input, and if it
is adequate, handles the failover to the redundant, secondary AC input until
the primary input is restored.
Each dual AC power module includes both primary and secondary AC power
connectors and two breaker switches. There are four types of dual AC power
modules: dual AC, dual AC with convenience outlet, dual AC 2 (13 A), and
dual AC 2 (16 A). Dual AC with convenience outlet and dual AC 2 power
modules include a fused 200‐240 VAC convenience outlet. The dual AC
convenience outlet is rated at 5 A. The dual AC 2 convenience outlet is rated at
2 A.

LEDs indicate the status of the primary and secondary AC inputs.
 Primary and Secondary Input Power LED States:
 Green ‐ Good/Active
 Orange ‐ Under Voltage
CAUTION! If the power sources for the AC inputs for a frame using the dual AC
or dual AC with convenience outlets are not on the same phase, damage to the
library could result.
