Specifications A-5
Environmental
➀ The product’s allowable operational ambient temperature must be derated by -3 °C (-27°F) per
1000 m (3280 ft.). Maximum operating altitude is 7000 m (23,000 ft.). Current rating of the SMC-Flex
does not change for altitudes that require a lower maximum ambient temperature.
