20. Mount the cables from the thermal switch
and current transformers the LV-Board. Mount the new HV-Board with the five
screws.

Be careful how you connect the cables
from the current transformers (correct
phase sequence). careful how you
connect the cables from the thyristors.16. Change the position the cables the
current transformers obtain correct
position necessary.

19. The resistance
of the current transformer are between
0,2-6 ohm. Mount the cables from the thyristors and
fans the HV-Board. the two cables each current
transformer are black use multimeter to
detect the right connection
