The internal parts from VSD's with IP55 enclosure must be dismounted in the following sequential order:
1. LCP, front panel and terminals
2. Heat sink fan
3. Optional relay card
4. Control card
5. Internal fan

It is recommended to keep each dismounted part grouped together with its screws. This will facilitate

Remounting non-defective or new parts must be done in reverse order (starting with the power card,
ending with the LCP).

The main fan is accessible from the outside of the aluminium housing.
• Unscrew the fan from its support.

The optional relay card (130B1110) is located below the LCP, if installed. It is plugged on the control card,
without any screws.
