Introduced into the system through the introduction of cable fixtures cold proof lights, from installation to use the entire process, if there is likely to be tension-proof lights, the introduction of the compression nut on the device or close to the introduction of the device inside the lamp to increase anti-pull off the cable clips, to prevent the force is transmitted to the mobile terminals and prevent the cable possible to prevent poor contact or failure of electrical connections. Lamps at design time may be required to provide more than one introduction means, user different installation requirements. At the factory, should be introduced in all of the devices are installed to block parts, structural block piece must fit the type of protection. Or, install only one entries, the rest (after the introduction of device removal) hole with a suitable type of protection bulkhead instead. Thus, the excess will not forget to block the introduction of device failure caused by flameproof enclosure. A selection of personnel must understand the basic principle proof lighting, explosion familiar logo. 2 hazardous locations according to an explosive level of proof lamp box, select the exact lamp explosion category, type, level and temperature group. 3 for use of environmental conditions and requirements of gas explosion-proof lights, a reasonable choice of explosion-proof lamps with various functions. For example: shell lamps explosion protection class IP43 for outdoor use at least or more. In the request to identify the color of the place, you can not use high-pressure mercury lamps and high pressure sodium lamp explosion, because the two sources significantly poorer color.
