IMPORTANT NOTES:
- For ratings and voltages not listed above consult Factory
- Standby ratings do not have an overload capability but can be used for the duration of the utility failure per ISO-3046,DIN6271 and BS5514
- Prime (Unlimited Running Time) ratings are continuous per DIN 6271 and ISO-3046 with 10% overload capacity
- Base Load (Continuous) ratings are continuous per DIN 6271, BS5514 and ISO-8528 with no sustained overload capacity
- Consult factory for Base Load ratings
- Altitude derate is 4% for each 1000 feet over 5000
- Temperature derate is 1% for 10°F over 100°F ambient

Ratings – Standby Ratings: Standby ratings are applicable for supplying emergency power for the duration of a utility power outage. Primary power to the installation is utility supplied. No overload capability for standby rating. Standby ratings in accordance with ISO 3046, BS55114, DIN 6271. Continuous Power Rating: Continuous power is the maximum power available for continuous duty. A 10% overload capacity is available for 1 hour out of 12 hours of operation. Prime Power ratings in accordance with ISO 3046, BS55114, DIN 6271. For additional information, please consult factory. Manufacture reserves the right to implement specifications or design changes without notice.
