1. The safety fence should be installed in a safe place and the environmental conditions can meet the requirements of the "use conditions" in the "General Specifications" of this manual.
2. The wiring of the intrinsically safe end (blue mark) and the non-intrinsically safe end of the isolation barrier shall be laid separately in the busway and each adopt a separate protection sleeve. No other power cords, including the power cords used in their intrinsically safe circuits, are allowed inside the wiring harness on the intrinsically safe side.
3. The conductor leading to the dangerous place should use the intrinsically safe conductor marked in blue. The copper cross-sectional area in the conductor must be no less than 0.5mm2, and the dielectric strength should be greater than 500V.
4. Before energizing and debugging the isolated safety barrier, it is necessary to pay attention to the type, wiring method, line polarity, etc. of the isolated safety barrier. Whether it meets the requirements in the design and product requirements, otherwise it may cause harm to people and equipment.
5. Never use megohmmeters to test the insulation strength between isolated barrier terminals. If you want to check the insulation strength of the system, you should disconnect all the wiring first, otherwise it may cause damage to the internal circuit of the safety barrier.
6. Before programming the safety barrier in the field, you must first disconnect all the wires and then connect it to the programmer, and then energize the programming, otherwise it may cause adverse consequences.
7. Field instruments connected to isolated safety barriers shall pass the explosion-proof test of the explosion-proof inspection department recognized by the State and obtain the explosion-proof certificate. The use of our isolated barrier may not require joint certification.
8. When designing, installing, using, and maintaining isolated barriers, observe the instructions in this product manual and “GB3836.15-2000 Electrical Equipment for Explosive Gas Environments Part XV: Electrical Installation in Dangerous Areas (Except for Coal Mines) ), "GB3836.15-2000 Electrical Equipment for Explosive Gas Environments Part XIV: Classification of Hazardous Locations, GB50058-1992 Explosion and Fire Hazard Environment Power Design Specification" and other standards.
