4.2 Connecting Power and Equipment
- Input Power: Connect the UPS input power cord to a dedicated, grounded 120V AC outlet. Ensure the outlet is rated for the UPS's capacity (30A for L5-30R).
- Output Equipment: Connect your critical equipment (servers, networking devices, etc.) to the NEMA 5-20R and L5-30R output receptacles on the rear of the UPS.
- The UPS features six NEMA 5-20R outlets and one L5-30R outlet.
- Four of the 5-20R outlets are grouped into two load banks, allowing for load shedding.
- Communication Ports: Connect the USB or serial cable from the UPS to your computer or server for monitoring and graceful shutdown capabilities.
- Optional Network Card: If using the optional NETWORK-M2 card, install it into the expansion slot and connect an Ethernet cable for remote management.
- Optional External Battery Modules (EBMs): If extending runtime, connect up to four 5PXEBM72RTG2 EBMs (sold separately) to the UPS according to their respective manuals.
4.3 Initial Power-Up
- After all connections are made, press the power button on the front panel of the UPS.
- The UPS will perform a self-test, and the display will illuminate.
- Allow the UPS to charge its internal batteries for at least 24 hours before relying on it for extended backup runtime.
5. Operating the UPS
