Environmental Specifications
The 1391-DES must be mounted in an enclosure that is clean, dry and ventilated by filtered or cooled air. Enclosures vented with ambient air must have appropriate filtering to protect against contamination caused by oils, coolants, dust, condensation etc. The ambient air temperature must be kept between 0 to 60° C (32 to 140° F) and the humidity between 5 and 95%, non-condensing.
The 1391-DES is equipped with an integral cooling fan. The general flow of air through the unit must be maintained by following the recommended spacing guidelines found in Chapter 7. The 1391-DES can operate at elevations to 3300 feet (1000 meters) without derating, however, the current rating must be derated by 3% for each additional 1000 feet (305 meters) up to 10,000 feet (3050 meters). Consult with your local Allen-Bradley Sales Representative prior to operation over 10,000 feet (3050 meters).
