The insulation housing shall prevent stray strands from shorting to adjacent terminal blocks. <br />I. The termination shall be gastight to prevent corrosion due to corrosive atmospheres. <br />J. Terminal screws shall be captive in the metal body or via the insulation housing. <br />K. Once tightened the terminal screws shall be locked in place to prevent loosening due to shock and <br />vibration. <br />L. The terminal block shall be useable with accessories such as center or insertion bridges; test sockets; <br />separating plates; and end covers, etc. The accessories used shall also be touch safe. <br />M. For wire identification, the terminal block shall provide space for marking with pre-marked labels. <br />Handwritten labels shall not be allowed. <br />N. Manufacturer/Model: <br />1. Allen Bradley <br />2. Phoenix Contact <br />3. ABB <br />4. Or Equal <br /> CONTROL PANEL WIRING <br />A. Stranded copper conductors with color-coded 600-volt insulation. <br />B. Both ends of all conductors identified with wire tags which are numbered in accordance with the wiring <br />diagrams, and which are protected with a clear, heat-shrinkable sleeve. <br />C. Complete wiring diagrams prepared specifically for this Site. All termination points shall be numbered. <br />D. Both ends of all conductors identified with wire tags which are numbered in accordance with the wiring <br />diagrams, and which are protected with a clear, heat-shrinkable sleeve. <br />E. Provide enclosed wire ways in the panel. <br />1. Wireways shall be mounted parallel or perpendicular to panel enclosure lines. <br />2. Wire ways shall have removable covers, which do not require the use of tools. <br />F. All spare PLC inputs/outputs shall be wired to terminal blocks. <br />G. Provide separate terminal block grouping or segments for digital inputs, outputs, analog inputs and <br />analog outputs. <br />H. Designated wire coloring shall be used to identify the function of the wire. Example, all digital input <br />cabling shall be a designated color different than digital output wiring. <br /> NETWORK COMMUNICATION EQUIPMENT (PROVIDED UNDER ALTERNATE 2 AND ALTERNATE 3) <br />A. Unmanaged Ethernet Switches <br />1. Unmanaged, store and forward wire speed switching. <br />2.
