Lifting out the module
1. Loosen the screwed connections ⑨ between the phase module frame and the insulators.
2. Raise the IGCT phase module a few millimeters. To do so, insert a washer on the screw
in each case. To do so, insert the screws from above through the lugs ⑩ on the front and
rear of the IGCT phase module. Tighten the nuts slightly.

3. Slide the two roller tracks under the raised frame of the IGCT phase module. Use the screws
which were previously used for the screwed connection of frame and insulators to fix the
roller tracks in place.

4. Position the stacker with the pre-mounted changing device in such a way that the roller
tracks under the IGCT phase module and the roller tracks on the stacker can be screwed
together.
