Grounding rail ACC-LBF-EB.6
For attaching Surge Protectors to the spur connections of Fuchs fieldbus couplers
R2-SP*, R3-SP*, and F4D0-FB-IA*, the optional grounding rail ACC-LBF-EB.6 is used
to provide a common earth point and mechanical support for up to 6 SCP-LBF-1.36* modules.
For Surge Protectors that are placed on both sides of the fieldbus couplers, 2 grounding rails
ACC-LBF-EB.6 are required. If fieldbus couplers are used with less than 6 spurs on one side,
the grounding rail can easily be cut or snapped to length.
The grounding rail provides a screw clamp to be connected to an equal potential bonding
system using a minimum cross core section of 4 mm
