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.

Please twist the plus and
minus power supply cables.
NOTE 1
Please prepare these parts beforehand.
NOTE 2
A cross section of power supply cable is 0.75mm² or 0.83mm² and
twist the plus and minus cable.
The power supply cable is shorter than 2m and lower inductance.
