Remote Emergency Power-off
REPO is used to shut down the UPS from a distance. This feature can
be used for shutting down the load and the UPS by thermal relay, for
instance in the event of room overtemperature. When REPO is
activated, the UPS shuts down the output and all its power converters
immediately. The UPS remains on to alarm the fault.
WARNING
The REPO circuit is an IEC 60950 safety extra low voltage (SELV) circuit. This circuit must be
separated from any hazardous voltage circuits by reinforced insulation.
CAUTION
SThe REPO must not be connected to any utility connected circuits. Reinforced insulation
to the utility is required. The REPO switch must have a minimum rating of 24 Vdc and
20 mA and be a dedicated latching-type switch not tied into any other circuit. The REPO
signal must remain active for at least 250 ms for proper operation.
STo ensure the UPS stops supplying power to the load during any mode of operation, the
input power must be disconnected from the UPS when the emergency power-off function
is activated.
NOTE For Europe, the emergency switch requirements are detailed in Harmonized
document HD-384-48 S1, “Electrical Installation of the Buildings, Part 4: Protection for Safety,
Chapter 46: Isolation and Switching.”

UPS Monitoring on the System i and AS/400
To set the system for UPS monitoring:
1. Set the QUPSDLYTIM system value for the UPS monitoring
feature.
2. UPS monitoring is a standard feature of the System i (AS/400)
operating system. QUPSDLYTIM is a timer that tells the system
how long to run on UPS power before shutting down. Each system
is initially assigned a default value for QUPSDLYTIM. A complete
description of QUPSDLYTIM is provided on the AS/400 Information
Center Internet Site at:
http://publib.boulder.ibm.com/pubs/html/as400/ic2924/info/index.htm
Select System Administration and Maintenance.
CAUTION
The *NOMAX value tells the AS/400 to use customized shutdown software, and if none is
available it will begin shutdown immediately when utility power fails. Do not set
QUPSDLYTIM to “*NOMAX” unless you understand the implications of the “*NOMAX”
function as described at the AS/400 Information Center Internet Site.

The Eaton 9130 front panel indicates the UPS status through the UPS
indicators (see Figure 7 on page 18).
Normal Mode
During Normal mode, the indicator illuminates solid and the UPS is
powered from the utility. The UPS monitors and charges the batteries as
needed and provides filtered power protection to your equipment.
The UPS may at times silently implement a High Alert mode, usually
when incoming utility conditions are unfavorable. In High Alert mode,
the UPS disables the battery support test to ensure maximum capacity
from the batteries if needed. The UPS will remain in High Alert for
24 hours or until changed by a Power Strategy command before
returning to its previous mode.
Optional High Efficiency and Energy Saving settings minimize heat
contribution to the rack environment. See “User Settings” in the UPS
user's guide.
Battery Mode
When the UPS is operating during a power outage, the alarm beeps
once every five seconds and the indicator illuminates solid.
When the utility power returns, the UPS transfers to Normal mode
operation while the battery recharges.
If battery capacity becomes low while in Battery mode, the indicator
flashes slowly and the audible alarm beeps once every second. If the
“Battery Low” alarm is set, the indicator also illuminates solid. This
warning is approximate, and the actual time to shutdown may vary
significantly.
NOTE Depending on the UPS load and the number of Extended Battery Modules (EBMs)
connected, the “Battery Low” warning may occur before the batteries reach 25% capacity.
Refer to the UPS user's guide for estimated runtimes.
When utility power is restored after the UPS shuts down, the UPS
automatically restarts.
