7.3.4 Assembly principle for connection joints with protection type
IP68
Step Action
1 Remove the two transport protection steel plates at the end of the
busbar elements (on the non-jointed side) and dispose of them.
2 Remove the 4 covers for the joint block (flanges of the joint block).
3 Before connecting, make sure that the ends of the busbar elements and
the joint block are clean and undamaged.
4 Insert the ends of the busbar elements carefully into the joint block.
5 Push the two elements together so that the distance is 220 mm. Take
care that the inner conductors in the joint block are all aligned evenly.
6 Tighten the shear-off bolt on the single bolt clamp until the
double-headed bolt shears off. This occurs at approximately 60 Nm.
7 Check the insulation resistance. It will not be possible to perform this
check after filling with the casting resin mixture.
8 Fit the side flanges.
