Installation of GCT Thyristor

GCT Thyristor is put on the gate driver to coincide with the holes

each other and covered by gate attachment at the ring gate of

GCT Thyristor. By screwing at each hole, GCT Thyristor is in-

stalled on the gate driver.

NOTE 1

Please prepare these parts beforehand.

NOTE 2
