This document provides installation instructions for SJE Rhombus control panel accessories, specifically the Riser Mounting Kit and the Simplex/Duplex Kit. It also includes a drilling template for the mounting post.
Riser Mounting Kit Installation

- Locate and Drill: Position the post next to the riser and determine the access hole location. Use a hole saw to create a 2 3/8" (6.03 cm) hole in both the riser and the post for conduit entry.
- Pre-assembly: Before mounting the post to the riser, pre-assemble the parts and cut the conduit so it extends 1 inch (2.54 cm) past the PVC washer.
- Final Assembly: Install the post to the riser by assembling the parts as shown in the diagrams. Solvent weld the male adapters to both ends of the conduit.
Simplex/Duplex Kit Installation

- Mounting: Mount the enclosure to the post by assembling the parts as shown. Refer to the template on the back of the manual for recommended hole locations.
- Sealing: Ensure the final assembly is secure. If all positions in the cord seal are not used, plug the open positions with the provided PVC plugs. Tighten the nut on the cord seal to prevent gas and moisture from entering the panel.
- Capacity Limit: The maximum enclosure size for the panel mounting post is 14 x 12 x 6.
Panel Mounting Post Template
The manual includes a full-scale template on page 2 for drilling the mounting post. When using the template:
- Align the edge of the template with the back wall on the top of the panel mounting post.
- Align the edge of the template with the back wall on the bottom of the enclosure.
- Use a hole saw to drill the large holes as indicated.
- The template provides specific hole sizes for various hubs, including 3/4", 2.0", and 2-1/2" hubs.
