1. Primary surge suppression shall consist of a wall or flush mounted unit with 12 AWG <br />terminals with a maximum 80kA (8/209s), protecting lines L -N, L -G, L -L, and N -G. The <br />unit shall meet the following environmental requirements: ambient temperatures of - <br />409F to 1859F (409C to 852C working) and 95% RH (non -condensing). Dimensions shall <br />be 4.5" x 2.9" x 2.3". <br />2. A nine -outlet (seven switched, two un -switched) rack mounted surge suppressor unit <br />shall be installed. The maximum surge current shall be 84kA with a load current of <br />15A or 20A, at a working voltage of 120V 50/60Hz. <br />3. A 19" DIN Rail kit assembly shall be installed and have enough space for 32 modular <br />surge suppressor devices (RJ11, RJ45, or BNC connector type) attached, meeting the <br />following criteria: ambient temperature of -402F to 1852F (-209C to 859C working) <br />and 95% RH (non -condensing). Dimensions shall be 5.04"H x .99"W x 2.25"D. <br />h) Common Grounding System: A floor mounted 12 -position ground bar shall be provided <br />with the cabinet. <br />i) Cabinet Construction: <br />1. The cabinet shall contain R-4 insulation to control the effect of environmental <br />conditions. <br />2. Cabinet shall be of 1/8", 5052 Aluminum construction with white powder coat finish to <br />eliminate rusting. <br />3. Doors shall have NEMA 311 rated with neoprene gasketing, for maximum equipment <br />protection, and shall have heavy-duty 3 -point hardware on all doors. <br />4. All hinges shall be 1/8" aluminum with a stainless steel piano hinge, or continuous door <br />length stainless steel hinges. <br />7.9.3 Field Device Cabinet Type III (332 Special) <br />Install field device cabinet that provides an environmentally secure enclosure to house ITS field device <br />equipment, subsystems and systems, lighting and surge protection. The cabinet shall be designed for the <br />explicit use of housing and protecting sensitive electronic equipment (Encoders, 10/100/1000 Ethernet <br />switches, media converters, port/terminal servers, fiber optics equipment, and other related <br />components, etc.) within a controlled environment necessary for the proper operation of installed <br />electronic equipment. <br />The detector cabinet shall meet or exceed the following minimum requirements: <br />a) Size: Outside dimensions shall be approximately 66"H x 24"W x 30"D; <br />b) Lighting: The cabinet shall include door activated 20W cool white fluorescent lights; <br />c) Electrical Outlets: One duplex (GFI) receptacle shall be included with every cabinet; <br />d) Equipment Racks: One 19" equipment rack, adjustable 4 -post design, with 5/8" - 5/8" — <br />1/2" spacing with holes tapped for #12-24 screws, a rack -mounted drawer shall be <br />included with the rack; <br />e) Air Filtration: The cabinet shall contain a filtered air intake vent featuring re -usable, <br />washable type filters; <br />f) Power Distribution: The 30A main breaker provided in the cabinet shall distribute power <br />to rack mounted equipment, lighting, and outlets; <br />g) Surge Protection: <br />1. Primary surge suppression shall consist of a wall or flush mounted unit with 12 AWG <br />terminals with a maximum 80kA (8/209s), protecting lines L -N, L -G, L -L, and N -G. The <br />unit shall meet the following environmental requirements: ambient temperatures of - <br />409F to 1859F (-409C to 859C working) and 95% RH (non -condensing). Dimensions shall <br />be 4.5"H x 2.9"W x 2.3"D. <br />37 <br />
