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 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 may 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.
The following basic UPS system configurations are possible:
S
Single UPS with two common battery UPMs and two to four battery cabinets for
both UPMs
S
Single Plus 1 UPS with two common battery UPMs, a common battery FI-UPM,
and two to four battery cabinets for the UPMs
S
Single UPS with two separate battery UPMs and two to three battery cabinets per
UPM
S
Single Plus 1 UPS with two separate battery UPMs, a separate battery FI-UPM,
and two to three battery cabinets per UPM
S
Single UPS with two common battery UPMs and a standalone common battery
rack system
S
Single Plus 1 UPS with two common battery UPMs, a common battery FI-UPM,
and one standalone battery rack system for the UPMs
S
Single UPS with two separate battery UPMs and two standalone separate battery
rack systems
S
Single Plus 1 UPS with two separate battery UPMs, a separate battery FI-UPM,
and one standalone battery rack system per UPM
S
Distributed bypass system with two to five UPSs and a customer-supplied
tie cabinet
The UPS system configuration can be enhanced by adding optional accessories such
as a Remote Emergency Power-off (REPO) control, RMP II, or X-Slot communication
cards.
