Application:
1. explosive atmospheres Zone 1 and Zone 2;
2.combustible dust Zone 21 and Zone 22;
3.IIA, IIB and IIC groups explosive atmospheres;
4.Designed for explosive hazardous locations such as oil refinery, storage, chemical, pharmaceuticals,military industries, etc.
5.Designed for wiring/ branching.
Installation:
When installing, open the junction box cover and the introduction device, select the appropriate inner diameter of the sealing ring according to the outer diameter of the cable, and then pass the cable through the compression nut of the introduction device, the gasket and the sealing ring are connected to the cavity, and fasten. The compression nut seals the cable, the introduction device that does not introduce the cable replaces the cable with a plug, and tightens the compression nut. Connect the wire to the corresponding position of the terminal block, connect the grounding wire, close the cover, and fasten the cover with bolt.
