InfraStruXure Power Generation System 81
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. However, the following sections will not apply to your system and should be disregarded:
“Generator start sequence” on page 7
“Generator cool-down” on page 7
“Fuel monitoring/runtime calculation” on page 9
“Communication converter,” (item 4) on page 13
“Resetting automatic operation on the generator” on page 20
“Generator” on page 37
“Fuel Alarm Limits” on page 44
Note
If your installation includes a secondary utility source, the APC Field Service Engineer
performing your start-up will configure your ATS to operate with two utility sources.
