Disconnect the rectifier unit or the converter from the power supply and
and switch OFF the unit. Remove the 24V power supply for the
electronics. Take off all connecting leads.
Optional boards are mounted when the power section is already
installed.
♦ Loosen the 2 fixing screws on the front of the unit at the top. There
is no need to remove the screws completely, since cutouts are
provided in the housing to permit the front to come away after the
screws have been loosened.
♦ Carefully swing the upper front section forwards (approx. 30 °) away
from the housing.
♦ At the power section, open the locking lever of the ribbon cable that
connects up with the control electronics.
♦ Take off the front of the unit by moving it forwards.
♦ Remove the cover of the selected slot on the front panel.
♦ To do so, you must carefully cut through the four connecting points
of the cover on the front panel with a thin knife or remove the
existing blind caps.
♦ Undo the two optional board screws by about one turn each.
♦ Loosen the connection between the system connector and the
board so as to prevent any mechanical tension arising when the
screws are fully unscrewed.
♦ Take out the optional board screws and remove the board.
