Guidelines for Installing an Island Grounding System Definition: Island grounding system In an industrial environment the electrical equipment is usually grouped into specific areas or islands. A grounding system does not necessarily have to cover the entire building. Instead, the islands grouping together electronic equipment should be defined. When electronic equipment is grouped into an area that is larger than approximately ten square meters, a cage measuring 3 m2 to 5 m2 should be created by interconnecting the different grounding structures and enclosures. A grounding cell is created by daisy chaining the grounding points. This can be cabinets, machine chassis and metallic cable ducts :
NOTE: Sensor and actuator cables outside of these islands must be shielded with great care!
