Thyristor module location in T5 units
Notes:
− All T5 units feature 6 thyristor modules (only one of the two thyristors is used due to cooling reasons).
− This drawing is only showing the location of the thyristor modules, the actual unit module size is different!
Thyristor module terminals
The next figures show the terminals of the used thyristor modules. The terminal description is also stamped or
marked by a sticker on the thyristor modules.
For all firing pulse cables is valid:
− Yellow is gate lead.
− Red is cathode lead.
