
Cross head screwdriver
The I/O panel is fastened to the back side of the Energy Manager and to
the back of the Extension Board with four screws. It can be removed
without releasing the attached connectors. Thus the Energy Manager can
easily be replaced.
If there is enough space left behind the Energy Manager, you can remove
the I/O panel from the 50 pin plug connector. If there is not enough
space, you have to pull the Energy Manager out with the I/O panel about
20 cm or rotate the Energy Manger by 90 degrees then remove the I/O
panel form the 50 pin plug connector.
