Conditions Of Acceptability
The installation was not evaluated. The ESS shall be installed in accordance with applicable local installation code NFPA 70, IEEE C2, ICC IFC, ICC IRC, NRC NFC, NFPA 1, NFPA 855 and etc. as applicable.
The altitude shall be less than 3000m.
Ratings for salt-fog were not declared; additional evaluation shall be considered for systems to be installed in marine applications.
Installations were not evaluated for High Seismic active areas.
Final separation distances should be addressed in the final system installation requirements.
The DC ESS is intended for stationary applications. ESS will be installed on site using a (PCS) Power Conversion System and additional components.
The DC ESS is considered a pollution degree (PD) 3 and an overvoltage category (OVC) III.
Power Conversion System is not a part of this evaluation. Further evaluation shall be considered on product when the ESS subassembly is integrated with the power conversion equipment.
The DC ESS is only intended to be used with the Lunar (PCS) Power Conversion System and the intended Lunar system installation design.
