Distributed Bypass System
There are two types of redundancy: UPS based (based on the number of UPS units)
and UPM based (based on the number of UPMs). Each UPS contains three or four
UPMs.
A distributed bypass UPS system with two to five UPS units can be installed to
provide a 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 UPM is taken out of service for maintenance or is
not operating properly, a redundant UPM continues to supply uninterrupted power to
the critical load. A Powerware Hot Sync
provides connectivity and operational mode control. The distributed bypass system
consists of two to five UPS units each with a parallel CAN card, and a
customer−supplied tie cabinet or load distribution panel to act as a tie point. The tie
cabinet should contain Module Output Breakers (MOBs) with dual auxiliary contacts
for control of the system.

Monitoring and Communication
S
Remote Monitor Panel II (RMP II) – An optional RMP II contains backlit status
indicators and a local horn, allowing monitoring of the operational status and alarm
condition of the UPS from virtually any location within the facility.
S
Relay Interface Module II (RIM II) – An optional RIM II uses relay contact closures to
indicate the UPS operating status and alarm condition.
S
Supervisory Contact Module II (SCM II) – An optional SCM II establishes an interface
between the UPS system equipment and the customer's monitor.
S
X−Slot Cards – Optional X−Slot cards support several protocols, such as SNMP,
HTTP, IBM
AS/400

S
eNotify Remote Monitoring and Diagnostics Service – An optional service that provides
24/7 remote monitoring of 43 alarms, temperature/humidity and battery charge
information, daily heartbeat check, and monthly report. The service also provides
customer notification of significant alarms, remote diagnostics, and dispatch of
technicians. A ConnectUPS−X Web/SNMP Card is required in an X−Slot
communication bay. An optional Powerware Environmental Monitoring Probe
(EMP) is required for temperature/humidity monitoring.
See Chapter 8, Communication," for additional information on monitoring and
communication features.
Although not provided with the UPS, a battery system is required to provide
emergency short term−backup power to safeguard operation during brownouts,
blackouts, and other power interruptions. The battery system should be equipped
with lead-acid batteries. An external battery disconnect switch must be used.
The UPMs may be powered with either a common or separate battery system. In a
common battery system, single and multiple UPMs are powered from one common
battery source. In a separate battery system, multiple UPMs are each powered from
separate battery sources.
UPMs in distributed bypass and parallel systems must use a separate battery system.
A supplemental 48 Vdc shunt trip signal for the battery disconnect device is provided
by the UPS, but is not required for normal operation.
