Operators should pay attention to the following points when assembling intrinsically safe equipment:
Ensure Reliable Installation of Internal Printed Circuit Boards:
The installation of internal printed circuit boards should be securely executed to maintain their functionality and safety.
Secure Internal Wiring Connections:
It’s crucial to ensure that all internal wiring connections are firmly secured, preventing any potential disconnections or malfunctions.
Maintain Adequate Protection Level of Enclosures:
The protection level of intrinsically safe enclosures should not be less than IP20, while the safety protection level for mining equipment should be at least IP54.
Installation Compliance with GB3836.18-2010:
The installation of intrinsically safe systems must comply with GB3836.18-2010 “Explosive Atmospheres – Part 18: Intrinsic Safety ‘I’ Systems” requirements.
Ensure Reliable Grounding of Safety Barriers:
Safety barriers must be effectively grounded to ensure proper functioning and safety.
