Fasten the cable to the cable bracket underneath the heat-shrinkable splitting cap; use a clamp.
Optionally: Mount a zero-sequence current transformer between the cable clamp and the rubber
sleeve. When doing so, lead the earth connection back through the zero-sequence current
transformer.

Mount the connection bar (3) as interconnection between the earthing busbar and the bottom
pan. To do this, remove the connection bar from the earthing busbar.
Lead the cable lug of an earth connection to the connection bar of the earthing busbar, apply it
to the bolted joint size M8 and bolt tight.
Bolt one cable lug each to one of the connection points of a phase, without distortions and gaps,
using the supplied connecting elements.
The bottom pan, the cables and the cable sealing ends are mounted in the connection
compartment.
