System Configuration - Vertiv Liebert Installer/User Manual

2.5 System Configuration

A UPS system comprises a number of equipment cabinets, depending on the individual system design requirements. In
general, all the cabinets in an installation are the same height.
NOTE: If you are bolting cabinets together, remove the side panels before beginning installation.
• UPS with connected battery cabinets—The battery cabinets are connected to the UPS and internally wired.
The battery cabinets must be installed on the right of the UPS in a connected system. On 600-kVA and lower
models, the battery-wiring cabinet is a separate cabinet installed on the right side of the UPS between the UPS
and battery cabinets.
• Stand-alone, interconnected battery cabinets—Shown in Figure 2.3 on page 8, with the battery-junction
cabinet on one end. The battery cabinets are interconnected with the battery-wiring cabinet, but are not
connected to the right side of the UPS. In this configuration, the battery-junction cabinet may be on either end
or between the battery cabinets.
• Stand-alone battery system—The battery-cabinet system stands alone. In this configuration, there is no
junction cabinet, and the battery cabinets are not connected to the UPS. Battery power cables are routed
directly to the DC busbars in the UPS I/O cabinet.
NOTE: Make sure that you complete all cabinet and battery interconnections before making any power cabling
connections. The interconnects are very hard to access after the power wiring is complete. Refer to the submittal
drawings that shipped with the battery system, or contact your Vertiv sales representative for the drawings.
The detailed arrangement and cabinet dimensions for your Battery Cabinet is described in the installation drawings. Refer
to the appropriate illustrations for your unit included in submittal drawings that shipped with the battery system, or contact
your Vertiv sales representative for the drawings.
