Cascade Battery Enclosures

If you have multiple Battery Enclosures as part of your InfraStruXure system, you can cascade Battery Enclosures to form a “daisy-chain” to a Symmetra PX UPS. Starting with the Battery Enclosure furthest away from the UPS:

1.Route DC output cables and the ground cable (coiled on the floor of the enclosure) from one Battery Enclosure to the next Battery Enclosure through the adjacent holes in the side panels of the enclosures.

2.Connect the DC output cables from one Battery Enclosure to the DC Input Breaker of the next Battery Enclosure [(+) to (+), (CT) to (CT), (–) to (–)].

3.Connect the ground wire from one Battery Enclosure to the grounding stud on the next Battery Enclosure.
