4 All single-phase units are rated at Power Ratings:The standby rating is applicable to varying loads for the duration of apower outage. There is no overload capability for this Power Ratings:At varying load, the number of generator set operating hours is unlimited. A 10% overload capacity is available for onehour in twelve. Ratings are in accordance with ISO-8528-1 and ISO-3046-1. For limited running time and continuous ratings, consult the factory. Obtain technical information bulletin (TIB-101) for ratingsguidelines, complete ratings definitions, and site condition derates. The generator set manufacturer reserves the right to change the design or specifications without notice and without any obligation or liabilitywhatsoever.
