Suitable Mounting Locations
Mount the Zone Panel Expander near the Main Panel. If desired, the expander panel can be mounted up to
500 feet from the main panel. The panel can be mounted in any orientation on a wall, stud, roof truss, or the
return-air plenum. For appearance, mount the panel near the main panel for easy panel to panel wiring.
Remove the panel cover and use the base as a template to drill mounting holes (see Figure 2). Attach the
panel with appropriate screws. Use mounting anchors as needed for drywall or plaster installations.
