Mount the guide pins the bottom heatsink.

lubrication.

• Drip couple drops silicone oil on
the cleaned contact surfaces, avoid
getting oil the guide hole. Then wipe the surface
in order get very thin layer oil.
The contact surfaces must dry before
lubrication.

• Lightly polish the contact surface f
semiconductor (the nickel layer must not
be polished through) with abrasive cloth
P600 which fix flat surface.
• void contact with surface. Preparation heat sink and semiconductor.
Place the semiconductor the right direction.
• Lubricate directly after
polishing/cleaning, within minutes. Check the semiconductor's symbol and type
specification. Smooth the
oil lightly over the whole surface using
lint-free paper. Rem ove the faulty thyristors.
• Use well moistened lint-free paper.
• Clean all polished contact surfaces
carefully with Ethanol.
