According to 5^th appendix of CEE directive about machineries

Up to eight rings: the terminal of the brushes are on a single side. Above eight rings they are alternated on two sides.

In the picture there are all the 15 rings that can be provided with numeration corresponding at the terminal board. If less the exceeding rings are not provided and the numeration counts for the number of rings provided.

DIRECTIONS FOR USE AND ASSEMBLY

The collector can be assembled with the nuts up or down. The seal vs. dripping is better with the nuts up. The ring part (pipe) must be jointly fixed at a support with maximum thickness of 28mm with either a threaded hole Æ48 pitch 1,5 or with a passer-by hole Æ50 mm or Æ53 mm looking that it cannot turn, clasping carefully the nuts. The brushes part, turning as regard to the rings-part, must be dragged with the special peg (dragging peg in the picture). Before the final clamping of the commutator let the raising cable pass in the pipe (if necessary). Unthread the cap “B” to execute the connections at the terminal board of the rings. The inspection of the terminals of the rings-part or to the terminals of the brushes is easy even at work and with the passer by cable, unthreading the cap “B” and the custody “A”, without removing the linked cables. Usually, until eight rings, the collector has got one pipe union for each side. Above eight rings there are two pipe unions. You can assembly the second pipe union on demand, with the collector already at work. The rings must always be clean and polished to avoid abnormal consummation of the brushes. Remember to remove occasional carbon-deposits caused by discharges. Be sure to hold the heads of the cable grips, the ferrule that holds the cap, and the nuts that fix the custody closed.
