Control Panels Technical Requirements for Integrated Automation System
- Provide control panels with suitable brackets for wall mounting, unless noted otherwise, for each control system. Locate panel adjacent to systems served. Mount center of control panels 60 inches above finished floor or roof. <Coordinate with the Design Drawings>
- Interior Panels: Fabricate panels of 16-gage furniture-grade steel, totally enclosed on four sides, with removable perforated backplane, removable hinged door and keyed lock, with manufacturer’s standard shop-painted finish and color. Control Panel enclosures shall be NEMA 1 rated. Lock shall be keyed identical for all Digital control panels provided for this project.
- Exterior Panels: Provide 16-gage 304 or 316 stainless steel NEMA 4X enclosures. Panel shall have hinged door, keyed lock, and integral, thermostatically controlled heater. Provide hinged dead front inside panel when flush-mounted control and/or indicating devices are included in panel. Fiberglass or aluminum, as applicable, to be used when gases that are being used in the panel area are corrosive to stainless steel.
- Provide UL-listed cabinets for use with line voltage devices.
- Control panel shall be completely factory wired and piped, and all electrical connections made to a terminal block. All wiring from field devices must terminate on Terminal Blocks. Connections made in the panel shop will then interconnect from the Terminal Block to the Controllers.
- Provide a 6 inch x 6 inch minimum wire way (metal wiring/tubing) trough across the entire width of the panel mounted to the top of the panel with close nipples of sufficient size for additional 50 percent wiring and tubing capacity. Wire ways shall not be less than 24 inches in length. Control panel wiring shall be installed and distributed in the wire way to minimize routing of wiring and tubing within the control panel. Wire way construction to be the same as the associated control panel.
- Each control panel shall have a power transformer with integral disconnect switch and 120V Power outlet as defined on the IAS drawings. <Coordinate with the Design Drawings>
- All Digital Control panel wire/tubing paths shall be housed in Panduit (open slot wiring duct with cover).
- Each Control Panel shall have permanently affixed lamacoid label with the following information:
- Control Panel number (DCP-1, DCP-2, NCP-X etc.).
- Equipment served (Chiller 1, AHU-1, etc.).
- Circuit Breaker number feeding panel.
- All gauges and control components shall be identified by means of nameplates.
- Complete wiring and tubing termination drawings shall be mounted in, <and a second set mounted adjacent to,> each panel in a frame with lexan cover of sufficient size to be easily readable.
- Sheet metals screws shall not penetrate the cabinet walls, door, or back.
