The following options for the Eaton 9155 are available:

The parallel tie cabinet is used to connect up to three UPSs providing parallel capacity and/or redundant system.
This load sharing system provides more capacity than a single UPS and can provide backup, depending on the
load and configuration. In addition, when one UPS is taken out of service for maintenance or is not operating
properly, a redundant UPS continues to supply uninterrupted power to the critical load. A parallel Powerware
Hot Sync Controller Area Network (CAN) Bridge Card provides connectivity for system metering and
operational mode control. The parallel system consists of two to three UPSs, each with a parallel CAN Bridge
Card, and a parallel tie cabinet.

The optional MBM is installed on the UPS rear panel and is used to bypass the UPS during maintenance or
servicing. The maintenance bypass switch on the MBM provides a Make-Before-Break (MBB) wrap-around
bypass for UPS service without shutting down the load.

The optional PDM provides the same functionality as the MBM and also comes equipped with several different
types of output receptacles.

The Eaton Bypass Power Module (BPM) is designed to be a maintenance bypass switch that also contains
flexible output power distribution and mounting options.
The BPM provides added reliability to Eaton uninterruptable power supply (UPS) systems by ensuring
seamless, uninterrupted, no-break transfer as well as a lock-out/tag-out (LOTO) feature to ensure the greatest
safety for UPS technicians and electricians. The BPM also offers output distribution in order to simplify wiring in
a rackmount IT environment, potentially removing the need for a panelboard, breakers, and conduit for
distribution.

The optional input isolation transformer is located at the bottom of a 3-high UPS model. The input isolation
transformer provides a neutral from a 208V or 240V input source with 240V output and can be wired to the UPS
or to an MBM/PDM.

The optional seismic kit secures the UPS and optional EBMs for Zone 4 seismic installations.
