warranty descriptions and the conditions shall be referred to the Individual Contract.
Atmospheric condition as per ISO 15550:2002 (JIS B 8003:2005) (Barometic pressure:100 kPa, ambient temperature:298 K,
relative humidity:30%).
*2: Average load factor (per day or year) shall be calculated as per the formula in ISO 8528:2005 'average power output (Ppp)'.
*3: Refer to Operation Manual for more information regarding inspection and maintenance including items and descriptions.
*4: Warranty aren't valid after Major Overhaul.
*5: For backup or emergency purpose engine, it is needed to have output margin of 5% or more for the customer demand output to
avoid engine stall by output tolerance (ISO 15550) and frequency variation etc.
*6: Although power is same as Prime rating, but DCC don't have overload. This point is influenced to step load performance. Then,
engine generator set manufacturer is required to check performance of the DCC rating engine.
*7: UPTIME compliant: This DCC rating meets the requirement of a Tier III and IV data center site with no runtime limitation when the
operation is loaded to 'N' demand for the engine generator set.
