service conditions.
Temperature
Operating
Average ambient temperature for any 24 hour period not to exceed 30°C (86°F), and
maximum temperature not to exceed 40°C (104°F). Average ambient temperature for any
24 hour period may be increased to 40°C (104°F),and the maximum temperature may be
increased to 50°C (122°F),if the load is decreased to 90%of standard rating. Minimum
