UNIT ENC8 - STEEL ENCLOSURE DIMENSIONS In inches (mm) 4.50 3.50 (114.3) (88.9) 4.00 4.15 (101.6) (105.4) DESCRIPTION This enclosure is designed for use with the CUB4, CUB5, DT8 & DT9 units. The enclosures are large enough to accommodate a Micro-line Power Supply (MLPS1) attached to the unit. These rugged enclosures are fabricated of formed steel with all seams welded to withstand NEMA 4/IP65 wash-down applications. The kits are coated with a durable black polyurethane finish. The holes for conduit fittings or other types of wiring connectors can be drilled through the removable rear access panel, or through the enclosure itself.
