Note:
1. To meet UL listing requirements with the H7CX-A11[] models, an OMRON P2CF-11-[] or P3GA-11 Socket must be mounted on the H7CX. 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.
