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: either
Source 1 or Source 2.
Source Label—Use a Source 1 label at the primary utility breaker to
identify which ATS it is feeding. Use a Source 2 label in instances
where a secondary utility breaker is employed instead of a generator.
Generator Label—Use these labels (3 total) at the generator to identify
which ATS it is feeding. Place one label on each long side of the
generator near the brand name labels, and place one label on the door
where the generator controller is located.
Single-Pole Label—Use these labels with each single-pole breaker on
the ATS distribution panel to identify which data center equipment it is
feeding. Use the marker (supplied) to write on the label.
Three-Pole Breaker Label—Use these labels with each three-pole
breaker on the ATS distribution panel to identify which data center
equipment it is feeding. Use the marker (supplied) 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 not employing 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 Dead Front Source Label—Use these alternate labels for Source
1 and Source 2 if you do not want Utility and Generator to describe
your sources. These labels allow you to use Primary and Secondary or
Normal and Alternate to describe Source 1 and Source 2.
