when loads are greater than 50% of the system rating. Therefore, shifting the load to fewer UPMs can achieve
higher efficiencies when the UPS load is lighter.
In VMMS mode, the UPS is actively monitoring the critical bus and UPMs are available to assume load in less
than 2 ms to respond to load changes.
The VMMS feature has three configurable modes of operation: Online mode, Online mode with VMMS, and
High Alert mode. All modes are selectable from the front panel.
VMMS mode supports both distributed bypass and SBM parallel configurations.
In High Alert mode, all idle UPMs go online for one hour. At the completion of the hour, the UPS defaults back
to VMMS mode. If the High Alert command is received during the one hour, the one hour timer will be
restarted.

The UPS system can be further enhanced by adding optional accessories such as a Remote Emergency Power-
off (REPO) control, RMP II, SCM II, RIM II, or X-Slot communication cards. See
Installing Options and Accessories
for additional information.
•
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.
•
Relay Interface Module II (RIM II)
– An optional RIM II uses relay contact closures to indicate the UPS
operating status and alarm condition.
•
Supervisory Contact Module II (SCM II)
– An optional SCM II establishes an interface between the UPS
system equipment and the customer's monitor.
•
X-Slot Cards
– Optional X-Slot cards support several protocols, such as SNMP, HTTP, IBM
®
AS/400
®
, and
Modbus
®
RTU.
•
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 Environmental Monitoring Probe (EMP) is required for temperature/humidity monitoring

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.
Consult the
Power Xpert 9395 Integrated Battery Cabinet (Model 1085 and 1085HR) Installation Manual
for
specifics on battery cabinet usage with the PowerXpert 9395.
A supplemental 48 Vdc shunt trip signal for the battery disconnect device is provided by the UPS, but is not
required for normal operation.
