The ENC16/18UL is a weather-resistant enclosure that is 16 inches wide and 18 inches tall. It is UL508A listed, with a UL listed NEMA 4X rated enclosure and components. The ENC16/18UL can house a data logger, a power supply, and at least one peripheral. This enclosure is recommended for applications that need to have multiple communication or measurement and control peripherals housed in the same enclosure. To maintain its NEMA 4X rating, the ENC16/18UL does not come with a standard Campbell Scientific ground lug. Users must bring a ground wire inside the enclosure through a conduit or cable entry seal and then ground it to a ground bar, DIN-rail mounting bracket, or something similar.
