140 gNote: 1. To meet UL listing requirements with the H7CX-R11@ models, an OMRON P2CF-11-@ or P3GA-11 Socket must be mounted on the H7CX. Otherwise,H7CX-R11@ 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 theH7CX and installation panel.■ Life-test Curve (Reference Values)Resistive LoadInductive Load1,000No.
