Mount the cables from the thermal switch
and current transformers the LV-Board. For upgrade Torque Control is
important check the connection the
current transformer (see fig below).
Be careful how you connect the cables
from the current transformers (correct
phase sequence). Change the position the cables the
current transformers obtain correct
position necessary. careful how you
connect the cables from the thyristors. Mount the cables from the thyristors and
fans the HV-Board. The resistance
of the current transformer are between
0,2-6 ohm.
