ETAS
Differences in case ground potentials can cause high currents to flow
through the shields of the cables that connect various system modules.
Ensure that the module mounting surfaces are at the same electrical poten-
tial or insulate the modules from their mounting surfaces.
Cabling
Use exclusively ETAS cables at the connections of the product! Adhere to the
maximum permissible cable lengths! Observe the assignment of the cables to
