If the floodlights are shut down, a 10-minutecool-down period is required before turning them back on.High pressure sodium floodlights require 1–2 minutes to start and 2–5minutes of cooldown time to restart.3.19 Stopping—LombardiniSee Graphic: wc_gr001426, wc_gr0027583.19.1 Turn the circuit breakers (a, b, c) off and remove any other loads fromthe generator.CAUTION: Never shut down the engine without turning off the lights.Damage to the generator will occur.3.19.2 Turn the key (q) to OFF.3.20 Stopping—CATSee Graphic: wc_gr001670, wc_gr0027563.20.1 Turn the circuit breakers (a, b, c) off and remove any other loads fromthe generator.CAUTION: Never shut down the engine without turning off the lights.Damage to the generator will occur.3.20.2 Turn the key (r) to “OFF”.3.21 DeratingAll generator sets are subject to derating for altitude and temperature.Although derating should not affect operation of the floodlights, it willreduce the available reserve power to the receptacle.Ratings are typically reduced 3% per 300 m (1000 feet) elevation fromsea level, and 2% per 10°F (5.5°C) increase in ambient temperatureabove 78°F (25°C).
