Backup Battery Module Gives Your Compatible Eaton UPS System Extended Runtime The 93PX2EBM480U offers extended battery runtime when used in conjunction with Eaton’s 93PX 3-phase UPS systems. It can also be daisy-chained for a maximum of four auto-detected pairs of 3U extended battery modules (EBMs) to deliver even longer extended-run operation. Heavy-gauge cabling with high-current DC connectors is included for safe, simple installation. Innovative Quick-Connect Design for Easy Plug-and-Play Deployment and Service Interconnections between the 93PX2EBM480U, UPS power module(s) and a maintenance bypass panel provide easy plug-and-play setup and serviceability. You can mount all UPS modules in an EIA-standard 19-inch rack using the included hardware, and connect the modules together using the included cables.
