1. The safety barrier should be installed in a safe place, and the environmental conditions should meet the requirements of the "application conditions" in the "Safety Barrier Selection Sample".

                               The principle of installation of safety barriers

2. The connecting wires of the intrinsically safe end (blue end) and non-intrinsically safe end circuits of the barrier safety barrier should be laid separately in the assembly duct, and independent protective sleeves should be selected for each. No other power cords are allowed in the wiring duct on the intrinsically safe side, including the power cords used in the intrinsically safe circuit.

3. The conductor leading to the risk place should be an intrinsically safe conductor marked in blue, the soft copper area of the conductor must be greater than 0.5mm2, and the dielectric strength should be greater than 500V.

4. Before powering and debugging the barrier safety barrier, it is necessary to pay attention to whether the model, wiring method, and line polarity of the barrier safety barrier comply with the rules in the design and product requirements, otherwise it may cause harm to people and equipment.

5. It is strictly forbidden to test the dielectric strength between the terminals of the barrier safety barrier with a megohmmeter. If you want to check the dielectric strength of the system, you should first disconnect all the wiring of the barrier barrier, otherwise it may cause damage to the internal circuit of the barrier.

6. Before programming the safety barrier on site, it is necessary to disconnect all wiring before connecting to the programmer, and then power on the programming, otherwise it may cause undesirable consequences.

7. The appearance of the site connected with the barrier safety barrier shall be selected through the explosion-proof test of the relevant explosion-proof inspection department determined by the state and the appearance of the explosion-proof certificate.

8. When designing, installing, operating, and protecting barrier safety barriers, the instructions in the operation manual of this product and the "GB3836.15-2000 Electrical Equipment for Blasting Gas Environments Part 15: Electrical Installation in Risk Locations (Except Coal Mines)" and "GB50058-1992 Design Code for Power Installation in Blasting and Fire Risk Environments" should be strictly observed.
