Vertiv APS EBC with 4 Vrla Battery Strings - AS7EBC4CCUBXLKB

Vertiv AS7EBC4CCUBXLKB External Battery Cabinet

Overview

The Vertiv AS7EBC4CCUBXLKB is a 14-bay Extended Battery Cabinet (EBC) designed to supplement the runtime of compatible Vertiv Liebert APS UPS systems. It houses four VRLA (Valve Regulated Lead Acid) battery strings, providing extended backup power for critical IT infrastructure, server rooms, and data closets. This cabinet specifically addresses scenarios where the UPS's internal batteries are insufficient for planned shutdown procedures or extended grid outages.

Compatibility

This EBC model, AS7EBC4CCUBXLKB, is engineered to integrate with the Vertiv Liebert APS UPS series. It is designed to work with the specific APS models that support external battery cabinets. Additionally, it utilizes standard EBC cables (APSEBCCBL1M, APSEBCCBL3M, APSEBCCBL5M) and can incorporate an optional 10 Amp charger module (APSCHRGRMOD) for use with third-party battery cabinets if needed, though this unit is pre-configured for VRLA strings.

Installation Notes

Installation requires connecting the unit to the host Liebert APS UPS using the appropriate EBC cable, ensuring correct polarity and secure connections. The cabinet must be placed on a level, stable surface capable of supporting its weight when fully populated with batteries. Ensure adequate ventilation around the unit to prevent heat buildup, as VRLA batteries can off-gas during charging. Refer to the Liebert APS UPS installation manual for specific wiring diagrams and power-up sequences.
