NSE9720 performance of high-efficiency gas discharge lamp as the light source, high luminous efficiency, no flicker, no glare, long life, average life of 10,000 hours or more. Protection angular design and the prism transparent pieces of technology, soft lighting, anti-glare effect, can effectively reduce the operation, construction irritation of the eyes, avoid discomfort and fatigue. The use of wide regulator, constant power technology and special circuit design. A type can be used as a normal working lighting, emergency functions; simplex type B as emergency lighting usually is turned off. A, B type in the main electrical power can immediately start emergency lighting, can also be initiated at any time during a power outage in the main electrical control external switch. Multiple anti-vibration design and high-strength alloy casing, to ensure the long-term security in the tracks in the roadbed, bridges and culverts, tunnels and other high-frequency vibration. Special sealing materials and surface coating, to ensure that lighting in the humidity, high temperature and other harsh environments never corrosion, rust. Seat, ceiling and wall-mounted variety of installation methods, illumination angle in accordance with environmental needs 180 ° up and down within the regulation. The NSE9720 use to determine the installation location of the lighting and power supply box, select the appropriate installation and ?8 three-core cable of the appropriate length of, and ?10 five core cable ready. In accordance with the installation requirements lamp and ballast box mounting, hand press two at the bottom of the lamp lid release button to raise the light front cover, and remove the fixed light bulb bubble. One end of the three-core cable through the Gülen joint introduction lamps, tighten the nut to prevent loose cables; lamps next to the Terminal Block letter "L" FireWire connection, "N" zero line, ground symbol grounding wire; then fasten the front cover. M5 hex wrench to open the ballast cover, remove the electronic ballast board. Introduction of lamps connected the other end of the three-core cable the ballast box output terminal, then the conductors to the output electronic ballast board the "L" and "N" and the ground terminal, after the five-core cable input device into the ballast tank, three larger-gauge wires connected to the electronic ballast board input of "L", "N" and the ground terminal, the smaller yellow, green wire to the electronic ballast plate "yellow", "green" Line of Control. Will be placed in the ballast tank battery black wire into the battery negative terminal of the electronic ballast board, and electronic ballasts into the box, fixed. The emergency function of the ballast circuit board to pull the switch to the OFF position, external remote control emergency lamps. Five core cable will be smaller yellow, green signal line directly access a control switch of the emergency power supply. The thicker three wires connected to the mains electricity live, neutral and ground lighting can be achieved. NSE9720 attention to the installation and maintenance must cut off the power. Replace the lamp, you should use the same type and power of the bulb; such as changing the bulb type or power, shall replace the corresponding ballast. Should you do not need to use the external switch control emergency, simply pull the emergency control switch to the "ON" position to power outage emergency functions. Multiple sets of lights with the same switch on-line control of emergency should be noted that the "yellow", "green" signal lines were connected to the same control line, non-cross-connect NSE9720 technical parameters Rated voltage: 220VAC 50Hz Enclosure protection: IP65 Emergency time:> 30 min (70W)> 80min (35W) Charging time: <20h Do the introduction of the cable: a ?6 to f8mm Dimensions: lamps: 340 × 270 × 193mm ballast box: 240 × 202 × 132mm Total weight: Lighting: 3.5kg ballast box: 6.2kg
