12.
• Lubricate directly after
polishing/cleaning, within minutes. Smooth the
oil lightly over the whole surface using
lint-free paper.
• Use well moistened lint-free paper.
• Clean all polished contact surfaces
carefully with Ethanol.
• void contact with surface.
13.
• void contact with the surfaces after
lubrication. Mount the guide pins the bottom heatsink.
• Lightly polish the contact surface f
semiconductor (the nickel layer must not
be polished through) with abrasive cloth
P600 which fix flat surface.
The contact surfaces must dry before
lubrication.
Place the semiconductor the right direction.

11.10. Connect the gate cables. Then wipe the surface
in order get very thin layer oil.
• Drip couple drops silicone oil on
the cleaned contact surfaces, avoid
getting oil the guide hole. Rem ove the faulty thyristors. Check the semiconductor's symbol and type
specification
