[ 50 Hz single-phase models are factory-connected as 230 volts. Field-adjustable to 220 or 240 volts by an authorized service technician.

] 50 Hz 3-phase models are factory-connected as 230/400 volts. Field-adjustable to 220/380 or 240/416 volts by an authorized service technician.

Note: The line circuit breaker is automatically selected based on the generator set model and voltage configuration.

RATINGS: Standby ratings apply to installations served by a reliable utility source. All three-phase units are rated at 0.8 power factor. All single-phase units are rated at 1.0 power factor. The standby rating is applicable to variable loadswith an average load factor of 80% for the duration of the power outage. No overload capacity is specified at this rating. Ratings are in accordancewith ISO--3046/1, BS5514, AS2789, and DIN 6271. GENERAL GUIDELINES FOR DERATING: ALTITUDE: Derate 4% per 305 m (1000 ft.) elevation above 153 m (500 ft.). TEMPERATURE: Derate 2% per 5.5_C (10_F) temperature increase above16_C (60_F). Availability is subject to changewithoutnotice. Thegenerator setmanufacturer reserves the right to change thedesign or specificationswithoutnotice and without any obligation or liability whatsoever.

Generator Set Sound Data Model 14RESA 8 point logarithmic average sound levels are 63 dB(A) during weekly engine exercise and 67 dB(A) during full-speed generator diagnostics and normal operation. For comparison to competitor ratings, the lowest sound levels are 58 dB(A) and 63 dB(A) respectively.*

All sound levels are measured at 7 meters with no load.

* Lowest of 8 points measured around the generator. Sound levels at other points around generator may vary depending on installation parameters.
