Power Redundancy

DC

Up to 8 power modules can be installed, and only 7are needed to be active at any time. This allows support for 7+1 power redundancy and A and B battery plant dual feeds redundancy.

AC

Up to 8 power modules can be installed, and only 4 are needed to be active at any time. This allows support for 4+4 power redundancy by using two independent AC power sources (4 feeds each).
