Operating Temperature: -40°C to+60°C. <br /> 2. Relative Humidity: 5 to 95%. <br /> 3. Operating altitude: 0 to 12,000 feet. <br /> 4. Audible Noise: Less than 35 DBA at 3 feet. <br /> B. Cabinet: <br /> 1. Provide a NEMA 1 cabinet with front accessible lockable hinged door(or screw-attached door)and for surface <br /> wall or equipment or building structure mounting as indicated. Provide over-current protection within TVSS <br /> cabinet. <br /> C. Monitoring: <br /> 1. Provide cabinet with LED visual status monitoring for indication of system operation noting that system is <br /> operating properly and visual LED status monitoring indication noting that the system has a fault. Provide <br /> cabinet with audible status monitoring that will alarm on a system failure in the event the protection has failed. <br /> Provide audible alarm silence push-button. <br /> D. Description: IEEE C62.41, selected to meet requirements for category indicated. <br /> 1. Exposure: Low. <br /> 2. Exposure: Medium. <br /> E. Impulse sparkover voltage coordinated with system circuit voltage. <br /> F. Factory mounted assembly with UL-recognized mounting devices. <br /> 2.03 EXTERNALLY MOUNTED PANELBOARD TVSS <br /> A. General: Design for non-linear loads that provide transient voltage surge suppression (TVSS) and high-frequency <br /> electrical line-noise filtering for Medium to Low Exposure levels at secondary distribution and branch circuit <br /> panelboards that are externally mounted adjacent panelboard. <br /> 1. Include coordination of TVSS equipment manufacturer installation with panelboard manufacturer. <br /> 2. Refer to drawings and/or panelboard schedules and to Section 16470 "Panelboards" for panelboards <br /> designated to be protected with TVSS. <br /> 3. Mount adjacent to panelboard as close as feasible, keeping feeder length as short as feasible; twist feeder <br /> conductors to reduce impedance. <br /> B. Operating Voltage: Refer to drawings and panelboard schedules for voltage and configuration. <br /> 16478-3 No. 01088 <br />
