To meet UL listing requirements with the H7CX-A11@ models, an OMRON P2CF-11-@ or P3GA-11 Socket must be mounted on theH7CX. Otherwise, H7CX-A11@ models are considered to meet UL508 recognition requirements.2. The Y92S-29 Waterproof Packing and Y92F-30 Flush Mounting Adapter are necessary to ensure IP66, NEMA4, and UL Type 4X waterproofing between the H7CX and installation panel.6Multifunction Preset Counter H7CX-A■ Life-test Curve (Reference Values)Resistive LoadInductive Load1,000No.
