A battery energy-storage system lacks a clearly identified means to isolate its power circuits. What is required?
- Provide the listed and identified disconnecting means required for the system
- BRely on opening the utility service
- CRemove hazard markings
- DUse software shutdown as the only isolation
Why A is correct
Stored-energy equipment can remain energized after utility disconnection. Listed disconnecting and shutdown provisions, identification, and manufacturer instructions must address the battery source itself.
