The isolated safety barrier produced by the isolation safety barrier manufacturer is a device used for intrinsically safe explosion-proof systems and used for safe isolation of field instruments. Explosion-proof systems and explosion-proof electrical equipment use isolated safety barriers in the design. Installed in a safe place, is a device that contains intrinsically safe circuits and non-intrinsically safe circuits.

The isolated safety barrier produced by the isolation safety barrier manufacturer is a device used for intrinsically safe explosion-proof systems and used for safe isolation of field instruments.

Explosion-proof systems and explosion-proof electrical equipment use isolated safety barriers in the design. Installed in a safe place, is a device that contains intrinsically safe circuits and non-intrinsically safe circuits.

The circuit limits the energy delivered to the circuit on site through the current limiting circuit to prevent dangerous energy outside the circuit from entering the circuit.

It is called related equipment in the explosion-proof system and is an important part of the system. Then, the following isolation safety barrier manufacturers take you to understand the installation precautions of the isolation safety barrier.

Isolation safety barrier manufacturers share the installation precautions of isolation safety barrier

Installation Note:

One. The isolated safety barrier should be installed in a safe place. The installation position should not have strong mechanical vibration, impact, and large current, spark, strong electromagnetic induction from the signal end, power end and space. The air should not contain metals and plastics. The gas that plays a serious corrosive role.

II. The wiring conductors of the isolated safety barrier intrinsically safe end (blue end) and non-intrinsically safe end circuits shall be laid separately in the bus duct, and each shall be provided with an independent protective sleeve. No other power cords are allowed in the wiring sleeve on the intrinsically safe side, including power cords used by other intrinsically safe circuits.

Three. The conductor to the dangerous place should be selected blue safety conductor, the soft copper area of the conductor must be greater than 0.5 mm2, the insulation strength should be greater than 500V.

Four. When the isolated safety barrier is energized and debugged, attention must be paid to whether the model, wiring method and line polarity of the isolated safety barrier meet the design and product requirements, otherwise it may cause damage to people and equipment.

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

VI. The field instruments connected with the isolated safety barrier shall be those that have passed the explosion-proof test conducted by the national explosion-proof department and obtained the explosion-proof certificate.

Seven. If the internal module of the isolation safety barrier is damaged and needs to be replaced, it shall be repaired together with the manufacturer, and can be put into operation again after maintenance.

Eight. The installation, use and maintenance of the isolated safety barrier shall strictly comply with the relevant provisions of the GB3836.15-2000 "Electrical Equipment for Explosive Gas Atmosphere, Part 15, Electrical Installation in Hazardous Places (Except Coal Mine)".

The above is the isolation safety barrier manufacturers introduced the installation of the isolation safety barrier precautions. If you need to know more, you can contact us at any time! Our company has many years of experience and looks forward to your joining at any time.
