InfraStruXure Power Generation System 11
Smart Distribution Panel with ATS
Front view, door closed
 Knockouts are provided on the roof, the
sides, and the floor of the ATS for
running utility and generator input wires
and for distributing power to equipment
in your data center. Connecting conduit
to the ATS does not require drilling. Use
a knockout punch to enlarge a knockout,
if necessary.
 The user connection plate is attached to
the ATS monitoring unit. The plate can
be removed, simplifying access to input
contact, relay output, network, and EPO
connections. These connections can
likewise be routed through a knockout in
the plate (see “User connection plate” on
page 16 for more information) to avoid
wiring complications.
 The bottom access panel can be
removed for better access to the panel
board. Use a #2 Phillips screwdriver to
remove the two M6 flat-head screws
securing the panel to the enclosure.
 The perforated steel front door protects
against ready access to the switches, the
circuit breakers, and the display interface
(see page 29). To access the display
interface without opening the front door,
simply remove the display’s Plexiglas
covering (see page 67 for instructions).
