3.07CONTROL PANELS

A.Refer to Part 2 - Products for construction details.

B.Field wiring shall be in conduit .

C. Panels shall be wall-mounted at eye level for accessibility and service.

D. Local control panels shall be located within same room of system served otherwise location shall be approved by UCCS HVAC Shop.

E.Control devices shall be installed in panels. Electro pneumatic switches (EPs) and relays shall be grouped together and installed in a single, central panel located next to the enclo- sure housing the associated controller. Remotely-mounted relays and EPs are not acceptable and PE switches are allowed unless preapproved by HVAC Shop.

F.Electrical power for each panel shall be from a dedicated circuit. For retrofit applications, where connecting to existing control-power wiring, it is Contractor's responsibility to verify that the power source is from a dedicated circuit. Side-by-side panels may be served by the same circuit, with separate disconnect for each panel. Notify the Owner if the source is not from a dedicated circuit. Where available in a building, utilize emergency-power circuits for all controls. [Note to Consultant: Coordinate power sources with the Electrical

Engineer, show all equipment requiring 120V power on the drawings.]

G. Mount panels on solid, non-vibrating surfaces. Where such surfaces are not readily accessible, mount the panel on a rigid, Unistrut stand attached to the floor. The sides of ducts and air-handling units are not acceptable mounting surfaces.

3.08IDENTIFICATION

A.All control equipment shall be clearly identified by HVAC shop drawing designation code and a functional description as follows:

1.Control valves: brass tags.

2.Other remote control devices and sensors: metal tags; plastic laminate labels; or, on non-porous surfaces only, permanent label tape as produced by the Brother “Easy Touch” label maker. Do not attach tag or label to removable covers, etc. Rivet or stick to device or adjacent surface.

3.Control panels: nameplate with panel number and systems served.

4.Devices in control panels: engraved plastic tags; metal tags; or, on non-porous sur- faces only, permanent label tape as above, mounted to panel adjacent to control device.

5.All wiring, including wiring within factory-fabricated panels, shall be labeled within 2"

of each termination with DDC point number/controller number or other descriptive
