Smart Distribution Panel with ATS 3
Overview
InfraStruXure Power Generation System
The InfraStruXure Power Generation System consists of a diesel-powered generator and a Smart
Distribution Panel with ATS. The ATS is connected to mains (Source 1) and the generator (Source 2),
with mains as the preferred source. The ATS is designed for the data center floor, which places the
ATS and the power distribution closer to your data center equipment. Labels on the ATS provide
quick visual indication of which ATS sub-feed breaker is supplying power to each piece of
equipment. The diagram below provides examples of data center equipment that can be connected to
the ATS.

Generator start sequence
The generator start sequence is followed only if the Crank setting in the Operating Settings menu
on the Generator Settings screen on the ATS display interface menu is set to Ye s . If it is enabled, the
following sequence will occur:
After a start signal is initiated, either by the ATS or manually, and the generator battery is good,
the generator engine will crank and the generator should start. If the generator does not start, it
will crank for the length of the Crank Time, and then rest for the length of the Rest Time. The
generator will repeat this pattern for the number of times set in the Crank Cycles before
stopping the attempt to start. Check the messages on the display interface for reasons why the
generator did not start.
Overview
On the generator controller interface, the LEDs track conditions during the start sequence:
LED Behavior on the Generator Controller Interface
Start sequence initiated: Generator Started: Generator Failed to Start:
Generator cool-down
After the load is powered by the generator, and mains returns and is powering the load, the generator
may enter a cool-down period. If the coolant temperature is above the Coolant Temperature Limit,
the generator will enter a cool-down period. During generator cool-down, the generator disconnects
the alternator from the output and then runs at idle speed for 10 minutes. After the idle speed time
expires, the generator will shut down. If the coolant temperature is not above the Coolant
Temperature Limit, the generator will not enter a cool-down period but will shut down after mains
returns and is powering the load.

Overview
Open and closed transfers
When a transfer is not occurring, one switch is ON and the second switch is OFF.
During a closed transfer, the second switch will turn ON before the first switch turns OFF, creating a
brief period of time when both switches are ON.
Closed Transfer
Source 1 Source 1 Source 2
Source 2
During an open transfer, the first switch will turn OFF before the second switch turns ON, creating a
period of time when neither source is connected (neutral time).
Open Transfer
Source 1 Neutral Source 2
You can set whether or not to Allow Closed transfers under the Transfer Setup item on the ATS
Setup menu on the display interface. (See page 35 for details on these settings.) If the Allow Closed
setting is Ye s , the ATS will always seek to perform closed transfers. In order for a closed transfer to
occur, the voltage and frequency for both sources has to be good; in addition, a closed transfer cannot
occur if the two sources are not synchronized. The ATS monitors for both sources to be synchronized
before transferring. If the time it takes for the sources to be synchronized exceeds the configured
Max Sync Time, the ATS will perform an open transfer instead. During a closed transfer, the ATS
also takes into account the time it takes for the switch to actuate, which creates a seamless transfer—
non-UPS-protected equipment will not be interrupted and the UPS time on battery will be reduced,
and in some cases, eliminated.
If the Allow Closed setting is No, the ATS will never perform closed transfers—it will always
perform open transfers. (See page 35 for details on these settings.) During an open transfer, the first
switch will turn OFF before the second switch turns ON, creating a period of time when neither
source is connected. This period is commonly referred to as the neutral time. The neutral time is
defined by the configurable Open Xfer Time.

Fuel monitoring/runtime calculation
Fuel monitoring is a unique feature of the InfraStruXure Power Generation System. Fuel level is
monitored at the generator (if purchased through APC) and load is measured at the ATS. These
measurements are used to calculate runtime, as explained in the following paragraph.
Fuel is monitored by a level sensor in the generator fuel tank (calibrated to the bottom of the fuel
tank) that changes readings every 12.7 millimeters of fuel level change. From these fixed level points,
the ATS counts the number of liters of fuel used (based on load over time) and subtracts this from the
fixed-level fuel amount to give an accurate estimate of fuel level. The remaining runtime is then
calculated based on the fuel usage rate at the current load and the remaining fuel in the tank. Once a
new fuel level point is reached, the value of the calculated fuel used is reset and the computation
begins again.
The Fuel Level and Runtime Estimate are displayed on the Generator Status screen on the ATS
display interface, and you can set the following Fuel Alarm Limits in the Alarms menu of the
display interface:
Overview
Percent Fill: If the amount of fuel as a percentage falls below this value, an alarm condition
exists.
Runtime: If the estimated runtime falls below this value, an alarm condition exists.

Overview
ATS label kit
ATS Label—Place this label on the outside of the ATS enclosure to
identify the ATS, and to associate it with the appropriate source 1 and
source 2.
Source Label—Use a Source 1 label at the primary mains breaker to
identify the ATS that it is connected to. Use a Source 2 label if you are
connecting to a secondary mains breaker instead of a generator.
Generator Label—Use three of these labels at the generator to identify
which ATS it is connected to. Place one label on each long side of the
generator near the generator brand name labels, and place one label on
the door where the generator controller is located.
Single-Pole Label—Use one of these labels with a single-pole breaker
on the ATS distribution panel to identify to what equipment the breaker
is feeding power. Use the marker (included) to write on the label.
Three-Pole Breaker Label—Use one of these labels with a three-pole
breaker on the ATS distribution panel to identify to what the breaker is
feeding power. Use the marker (included) to write notes on the lower
portion of the label. The labels are customized for typical components
in an InfraStruXure system. Blank labels are also included for
components that do not have pre-marked labels.
Front Bezel Label—If you are not using a generator for source 2, use
one of these labels to replace the Generator Power System label on the
left-hand side of the bezel. You can use either the Automatic Transfer
Switch or the Standby Power System label to describe your system.
ATS Deadfront Source Label—Use these alternate labels for source 1
and source 2 if you do not want Mains and Generator to describe your
sources. Using these labels, you can use Primary and Secondary or
Normal and Alternate to describe source 1 and source 2.

Operation
How to reset automatic operation on the ATS and on the generator
Resetting automatic operation on the ATS. If the Not in Automatic Operation LED is lit and
the Automatic Operation switch is in the Enable position, you need to reset automatic operation
after the event that caused this condition has been corrected. (See page 21 for a detailed description
of the events that might lead to this condition.) You can also clear certain alarms by resetting
automatic operation on the ATS. See “Clearing latched alarms” on page 44 for more information.
To reset automatic operation on the ATS, set the Automatic Operation switch to Disable () and
then back to Enable ().
Resetting automatic operation on the generator. If the ATS display interface reports a
generator shutdown alarm and the Alarm LED is red, you must reset automatic operation on the
generator to clear the alarm (the Shutdown LED on the generator control panel will also be red).
Events that lead to this condition include engaging the data center EPO switch and engaging the
E-Stop button on the generator. If any EPO was engaged, the switch must be disengaged before
automatic operation can be reset. If shutdown was not caused by EPO, contact APC service (see
“Service” on page 82). To reset automatic operation on the generator:
Set the
Acknowledge/Reset button on the generator control panel.
