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.
Lead the cable lug of an earth connection directly to the earthing busbar, apply it to the central
connection bolt size M12 and bolt tight, keeping the maximum possible distance to live parts.
Proceed in the same way with the other earth connections. Each cable sealing end must be
connected to the earthing busbar.
Bolt one cable lug each to one of the connection points of a phase, without distortions and
gaps, using the supplied connecting elements.
Check whether the minimum distance between the lower end of the cable lug and the upper
edge of the shielding cover is kept.

The bottom pan, the cables and the cable sealing ends are mounted in the connection
compartment.
