The following options for the Eaton 9155 are available:
S Maintenance Bypass Module (MBM)
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.
S Power Distribution Module (PDM)
The optional PDM provides the same functionality as the MBM and also comes
equipped with several different types of output receptacles.
S Wall-Mounted Bypass Switch
The optional wall-mounted bypass switch is used to bypass the UPS during
maintenance or servicing, providing wrap-around bypass for UPS service without
shutting down the load.
S Parallel Tie Cabinet
An optional parallel system with up to three UPSs can be installed to provide a
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. Refer to the Eaton 9155 Parallel UPS
(8–15 kVA) User's Guide for more information.
S Input Isolation Transformer
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.
S Seismic Kit
The optional seismic kit secures the UPS and optional EBMs for Zone 4 seismic
installations.
