The following options for the Powerware 9155 are available:
쑺 Maintenance B ypass Module (MBM)
The o ptional 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.
쑺 Power Distribution Module (PDM)
The o ptional PDM provides the same functionality as the MBM and
also comes equipped with several different types of output
receptacles.
쑺 Wall-Mounted Bypass Switch
The o ptional 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.
쑺 Parallel Tie Cabinet
A parallel system with up to three UPSs can be installed t o provide a
parallel capacity and/or redundant system. This load sharing system
provides more capacity than a single UPS and can provide b ackup,
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 Computer 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 Powerware 9155 Parallel UPS (8–15 kVA) User’s Guide for more
information.
쑺 Input Isolation Transformer
The o ptional 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.
쑺 Seismic Kit
The seismic kit secures the UPS and optional EBMs for Zone 4 seismic
installations.
