Working Principle:
The safety barrier limits the voltage and current that can pass into the hazardous area to levels below the ignition threshold of the explosive atmosphere. It uses zener diodes and resistors to clamp voltage and limit current, while providing galvanic isolation between the safe area and hazardous area circuits.
Installation Requirements:
- Install in safe area control panels
- Mount on DIN rail according to specifications
- Ensure proper grounding of safety barrier
- Separate intrinsically safe and non-intrinsically safe wiring
- Follow hazardous area classification requirements
- Maintain proper creepage and clearance distances
- Use approved cable glands and conduits
Usage Precautions:
- Installation must comply with hazardous area regulations
- Only qualified personnel should install and maintain
- Regularly inspect for damage or deterioration
- Ensure proper grounding connections
- Do not modify or bypass safety circuits
- Keep documentation for safety system verification
- Follow lockout/tagout procedures during maintenance
