The F1 miniature fuse is now accessible (see Figure 2-9).
Figure 2-9 Miniature fuse F1
Replace the miniature fuse F1 using the plastic tweezers by a fuse type which is identical or
recommended by Siemens.
Reassemble the device in reverse order.
Caution
Make sure that all components are correctly and fully inserted and that the locking levers are
safely engaged.
Caution
Please observe the following assembly notes when connecting the plug connectors of the ribbon
cables at the front cover with the pin contact strip of the CPU board:
•
The plug connectors of the ribbon cables each have one contact more than the pin contact
strips of the CPU board. For this reason, the topmost contact of the ribbon cable plug con-
nector is sealed with a pin. Therefore, plug the ribbon cable plug connector on the corre-
sponding pin contact strip offset by one contact.
•
When inserting the plug connectors of the ribbon cable, their lateral guides must face to the
outer sides of the pin contact strips of the CPU board.
•
Make sure that you actually feel the two ribbon cable plug connectors snap into the pin con-
tact strips of the CPU board.
