Control Panels
Control panels may be built into units, mounted in a separate electrical panel attached to equipment assemblies, or mounted as a separate electrical panel attached to the building structure.
If an electrical panel is mounted separately from the unit and the unit is vibration-isolated, use flexible electrical connections to allow for differential movement.
Step 1: Select control panel support configuration
If the control panel is:
- Built into the equipment, no other action is needed.
- An electrical panel attached to the assembly, check that the attachment is rigid and tight. No other action is needed.
- A remote panel attached directly to the building structure or attached using support angles or strut, continue with the following instructions.
The four ways of supporting control panels are by
attaching them to:
- Walls with wall anchors as shown in Figure 158.
- Vertical angles or strut extending down to the floor with angles slanted back to the floor as shown in Figure 155. This is the typical method. Details are shown in Figure 157.
- A double-strut support spanning the floor and ceiling as shown on the right in Figure 156. Struts are attached to the building structure with small angle clips.
- An aluminum plate extending from the floor to the ceiling. The aluminum plate is attached to the floor and ceiling with angles, as shown on the left in Figure 156.
Step 2: Assemble the mounting frame
Use bolts or weld support framing together as shown in Figures 155 to Figure 158. See Steel Bolt and Sheet Metal Screw Connections, or Welding for more information.
