Vertiv PSI5-48VCBL1 Concise Descriptor

Overview

The Vertiv PSI5-48VCBL1 is a 1-foot (300mm) EBC (External Battery Cable) extension cable designed to connect an external battery pack to specific Vertiv Liebert PSI5 series Uninterruptible Power Supply (UPS) units. This cable is essential for deployments requiring additional battery runtime beyond the internal capacity, ensuring critical equipment remains powered during outages. Its short length minimizes signal degradation and simplifies installation in tight spaces.

Compatibility

This PSI5-48VCBL1 cable is specifically engineered for use with the following Vertiv Liebert PSI5 UPS models that utilize a 48V external battery configuration: PSI5-1500RT120 and PSI5-1500RT120N. It is not compatible with other voltage configurations or UPS series.

Installation Notes

The cable facilitates a direct connection between the external battery module and the UPS unit. Ensure both the UPS and the external battery pack are powered off and disconnected from AC mains before making any connections. The 1ft length is ideal for situations where the external battery is placed directly adjacent to the UPS, such as within a shared rack or enclosure.
