ATEX / FM approved static earthing clamps and cables
If sites determine that ground monitoring status capability is not a requirement, basic grounding clamps with cables or cable reels can be specified.
Wherever the object requiring grounding is covered in product deposits or coated surfaces it is important to ensure the clamp teeth have penetrated to the base metal of the object. In addition cables should have a high mechanical strength to provide a reliable and repeatable connection.
Electrical continuity checks should be performed on a routine basis to check for wear and corrosion of metal parts and connections.
Factory Mutual tested grounding clamps can be specified in such situations. It is the ultimate responsibility of the end-user / site operator to ensure that solid and stable connections to the object(s) requiring grounding or bonding are made.
