Dual Power Feed Option
Dual power feed option is used to receive AC power for the main unit from two separated power
systems.
Connecting AC power of the main unit to two separate power systems provides redundancy, thus
the system can operate continuously, even if a power failure occurs in one of the input power
systems. PRIMEPOWER1000 requires this unit for the Base cabinet and each System
Expansion cabinet. Dual power feed option installation is required in both the Base cabinet and
the System Expansion cabinet.
When planning the installation of a UPS, note that a UPS needs to be installed for each power
line.
