Vertiv APS EBC with 2 Vrla Battery Strings - AS7EBC2CCUBXLKB

Vertiv AS7EBC2CCUBXLKB Extended Battery Cabinet

Overview

The Vertiv AS7EBC2CCUBXLKB is a 14-bay Extended Battery Cabinet (EBC) designed to augment the runtime of compatible Vertiv Liebert APS UPS systems by incorporating two VRLA battery strings. This unit is a critical component for deployments requiring extended backup power during utility outages, ensuring continuous operation for sensitive IT infrastructure in data centers and enterprise environments. It specifically addresses the need for increased autonomy beyond the internal battery capacity of the UPS itself.

Compatibility

This Extended Battery Cabinet, model AS7EBC2CCUBXLKB, is engineered for direct integration with Vertiv Liebert APS UPS units. It is designed to house and connect two VRLA (Valve Regulated Lead Acid) battery strings. Ensure your Liebert APS UPS model supports external battery cabinets and is configured to manage two VRLA strings for proper operation and battery management. The unit also supports optional accessories such as the APSEBCCBL1M (1 Meter EBC Cable), APSEBCCBL3M (3 Meter EBC Cable), APSEBCCBL5M (5 Meter EBC Cable), and the APSCHRGRMOD (10 Amp Charger Module for third-party battery cabinets), allowing for flexible deployment and charging strategies.

Installation Notes

Installation requires careful attention to battery string connection order and polarity. The EBC must be positioned close to the UPS to minimize cable length, especially when using the available 1m, 3m, or 5m EBC cables, to avoid voltage drop. The 10 Amp Charger Module (APSCHRGRMOD) is an optional accessory for scenarios where the primary UPS charger is insufficient or when utilizing third-party battery cabinets. Refer to the Liebert APS UPS installation manual for detailed wiring and configuration procedures specific to external battery cabinets.
