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.
