The unit has hazardous voltage levels up to 5 minutes after it has been
powered down due to the DC link capacitors. The unit or the DC link
terminals must not be worked on until at least after this delay time.
Disconnect the rectifier unit from the power supply and and switch OFF
the unit. Remove the 24V power supply for the electronics. Take off all
connecting leads.
Dismantle the unit as follows:
♦ Open the terminals of the DC link bus module.
♦ Remove the fixing screws by means of which the unit is fixed to the
mounting surface.
♦ Pull the unit down until the DC link bus module is completely
exposed.
♦ Pull the unit out towards you.
♦ Lay the unit on its left side.
If you are using an AC unit as a single drive, there is no DC link bus
module. You can then withdraw the unit directly after removing the
fixing screws.
♦ Unscrew the four fixing screws of the right-hand side wall. The fixing
screws are on the unit at the top on the right and at the bottom on
the right.
♦ You do not have to remove the four fixing screws completely, as the
wall of the unit is provided with a cutout to enable you to swing out
the cover once the screws have been loosened.
♦ Open the right-hand side wall. To open the side wall use a slotted
screwdriver to lever out the front panel from its latches. The front
panel only has to be loosened on one side of the side wall and can
stay on the unit housing. Now the side wall can be removed
upwards.
♦ 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.
