3.3.2 How to detach the custom interfaces
1. Switch off the mains voltage and wait a few
minutes as specified.
2. Loosen the 8 screws with which the in-
verter cover is attached and remove it.
Take care not to disturb the PE connection
(see the figure showing the PE connection
on the preceding page).
3. Use a srewdriver to ease the custom inter-
face out of its locked position (see figure
opposite). If this doesn't work unlatch the
hooks to the left and right. Pull out the
module completely with your hand.
4. Reattach all covers.
Don't forget to reconnect the PE con-
ductor. The device must never be op-
erated without a PE connection!
