Suitable for explosive gas atmospheres 1 and Zone 2 areas. Suitable for IIA, IIB, IIC explosive atmosphere. Applicable to combustible dust. Suitable for places containing corrosive gases. For wet, higher protection demand environments. Suitable for the energy requirements of the higher places. Features: Using the latest energy-efficient LED light source as the discharge, with the internationally renowned LED constant current power supply, stable, maintenance-free. With strong color and light effects, can replace a variety of existing light sources. It is one of the preferred energy-saving lighting project. Professionally designed light distribution system, high luminous efficiency, high utilization, with light reasonable, uniform illumination. High corrosion resistance of stainless steel exposed fasteners. Aluminum die-casting object, the surface electrostatic spray. Borosilicate glass transparent cover physical atomized design glare, anti-4J high energy impact, heat fusion, light transmission rate of 90%. Pure proof structure, only the mouth and explosion proof in the form of thread, explosion-proof performance and more reliable. Light chamber, power chamber, three-chamber separation structure wiring chamber, introducing indirect way, with a separate wiring compartment. Characteristics of the constant current power supply, wide input voltage, constant power output, with constant current, open circuit protection, short circuit protection. Technical parameters: Explosion-proof mark: ExdIICT6 Protection: IP65 Rated voltage: 220v-50Hz Line thread: G3 / 4 introduction of cable: 10 ~ 14mm light type: LED light source power: 30 ~ 50W Installation: Ceiling, pendant wall, flanged, fence type Usage: According to the site environment and lighting needs, determine the installation location of lamps and ballasts and proper installation. And from the 220V power supply contacts to prepare three core cable lengths according to corresponding ballast. In determining good mounting position, the lamps and ballasts fixed. Tighten fastening bolt with a socket wrench, three core cable cord through the introduction of ballast output device to the introduction of ballast cavity, respectively, of the cable to the terminals of the ballast, and then lead to three core card Cable and then tighten the compression nut pressing. Close the lid and tighten the ballast holding bolts, and then the other end of the three-core cable connected to 220V power supply to achieve lighting. When replacing the bulb, cut off the power. Note: When the installation and maintenance of lamps, must be cut off. Non-powered operation. When used, the lamps have a certain surface temperature is a normal phenomenon; Transparency center temperature is higher, not touch. If the external flexible cable or cord of this luminaire is damaged, the line is to be replaced by the manufacturer or its service agent or a qualified person. Quality assurance: strictly in accordance with ISO9001: 2000 international quality management system standards for quality control to ensure their quality is higher than the national standard, fully meet the design requirements, the product is 3-year warranty (lamp warranty for three years). Within 3 years from the date of purchase, under normal use of any failure by the company responsible for maintenance free.
