Replacing transistor module and diode stack
(i) Disconnect the leads which are connected to the
transistor module or stack and remove them from the
heat radiation fin.
(Note) Since part of the terminals G and E of the
transistor module is of the insert type, when
removing them,
take care of it.
(ii) Equally apply silicone grease on the rear side of
. .
the module or stack.
(iii) At the specified tightening torque (see the following
table),
mount the devices in the same direction as
the old ones and then connect the leads.
(Note) Put on the tube on the terminal G of the tran-
sis tor module.
