  • Page 13: Special Conditions Of Safe Use

    5.2. S PECIAL CONDITIONS OF SAFE USE Diameter of the cable should match the cable conduit. The cable outside the unit should be fixed so that it should be free of loading. The terminal box should be selected in accordance with the electrical class of the area. The device should read or programmed through IR port only outside of the explosive hazardous atmosphere because the infrared interface connected to the computer is not an explosion-proof apparatus.
