Overview InfraStruXure Power Generation System The InfraStruXure Power Generation System consists of a diesel-powered generator and a Smart Distribution Panel with Automatic Transfer Switch (ATS). The ATS is connected to both the utility (Source 1) and the generator (Source 2), with the utility as the preferred source. The ATS can alternatively be connected to a second utility.
How the InfraStruXure Power Generation System Operates Operation of the ATS during a utility failure when automatic operation is enabled Your data center equipment is typically powered by the utility [Source 1] (), while the generator [Source 2] remains off. When the level of incoming utility power falls below a specified threshold (), the ATS signals the generator to start ().
How the InfraStruXure Power Generation System Operates 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 is set to Yes. If 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.
How the InfraStruXure Power Generation System Operates Open and closed transfers When transfers are not occurring, one switch is ON and one 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.
How the InfraStruXure Power Generation System Operates 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.
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.
Smart Distribution Panel with ATS Front view, door open Remove the dead front to obtain access to the panel board for maintenance and wiring. The Source 1 motorized switch (see “Motorized switches” on page 15) controls operation of the Source 1 input switch.

Appendix: Custom Installations If Source 2 is a Second Utility Differences in your system from information presented in this manual The ATS was designed for operation with an APC InfraStruXure generator, and this manual assumes that Source 2 is an APC InfraStruXure generator. If using a secondary utility instead of a generator, almost all references to the “generator” should be considered references to your second utility as well.
If Source 2 is a Generator that is Not an APC InfraStruXure Generator Differences in your system from information presented in this manual The ATS was designed for operation with an APC InfraStruXure generator, and this manual assumes that Source 2 is an APC InfraStruXure generator. If using a non-APC generator instead of an APC generator, almost all references to the “generator” will still be applicable. However, non-APC generators will generally function differently than APC generators.
