External Battery Cabinets

Chapter 1       Introduction

The Eaton® External Battery Cabinet (EBC) provides extended emergency short-term backup power for the 
93E 80-200 kVA, 93E 300–400 kVA and 93PM 50-200kW UPS to enhance the usability and reliability of the 
systems. The EBC safeguards operation during brownouts, blackouts, and other power interruptions providing 
cost-effective extended battery run time. Two models are available, the Single EBC and Double EBC and are 
equipped with valve-regulated lead-acid (VRLA) batteries.

The EBC is housed in a single free-standing cabinet with safety shields behind the doors for hazardous voltage 
protection. Up to two EBCs per UPS may be used to meet application runtime needs. The cabinets match the 
UPS cabinet in style and color. 

Mechanical lugs located at the back of the cabinet reduce installation time, and removable battery trays with 
quick dosconnectors between trays reduce battery maintenance time. A DC-rated circuit breaker within each 
cabinet provides protection and servicing isolation.

Figure 1-1 shows the Eaton Single EBC and Eaton Double EBC.

Startup and operational checks must be performed by an authorized Eaton Customer 
Service Engineer, or the warranty terms specified become void. This service is offered 
as part of the sales contract for the EBC. Contact an Eaton service representative in 
advance (usually a two-week notice is required) to reserve a preferred startup date.

External battery cabinets cannot be used in combination with a UPS containing internal 
batteries. The UPS must be supplied without internal batteries.

NOTE 

NOTE 

The EBC is designed to be installed in a line-up-and-match or standalone configurations. In line-up-and-match 
configurations power wiring may be routed either external to the cabinet or pass wiring between adjacent 
cabinets. In standalone configurations power wiring is routed using external conduit. Connections are made to 
easily accessible terminals at the front of the cabinet.
