￭ Preparing the cable ends and making 360-degree grounding at the
cable entry
1. Peel off 3…5 cm (1 1/4 … 2 in) of the outer insulation of the cables at the cable entries
with the conductive sleeves for the 360° high-frequency grounding.
2. Prepare the ends of the cables.
WARNING!
Apply grease to stripped aluminum conductors before attaching them to
non-coated aluminum cable lugs. Obey the grease manufacturer’s instructions.
Aluminum-aluminum contact can cause oxidation in the contact surfaces.
3. If fire insulation is used, make an opening in the mineral wool sheet according to the
diameter of the cable.
4. Put the cables through the entry plate.
