Circuit (B6)A(B6)C (4-quadrant drive)
# Short-circuit proof cable installation
<1> Firing pulse transformer module inserted into the available plastic holders (following the order of the terminal names
shown in the figure).
Cables routed to the firing pulse transformers run from terminal strips XIMP_1 and XIMP_6 to XIMP11 (IMP11, P24) -
XIMP26 (IMP26, P24).
Firing cables X11 (K, G) to X26 (K, G) routed to the thyristors not shown
(X11 to X16 each routed to thyristor V01 in the thyristor double block, X21 to X26 routed to thyristor V02)
<2> Connection of the fuse monitoring equipment to the Faston tabs on the fuse holders.
The equipment for measuring the line voltage can be connected to the fuses in the thyristor blocks A1 (= AK1 = U),
A3 (= AK3 = V), and A5 (= AK5 = W) (see circuit diagram below).
<3> Do not connect X1, X2
<4> Measurement of armature voltage: connection of KW (AW) - C and AW (KW) - D
