ATTENTION!
!
The case may only be opened by experienced personnel when the power to the process
control station has been cut off!
Re-jumpering (see section 4.) or retrofitting the process control station with an interface board
requires that the case be opened as follows:
1. With panel-mounting cases, remove small paper labels (see 1, Fig. 3 ) if necessary. With
19inch rack-mounting units, remove the two protective nipples. Unscrew the two screws
located on the front-panel of the case (see Fig. 3 or Fig. 4 , depending on the type of
case).
2. Withdraw controller section towards the front. Then, proceed as described for the
respective PCB to be modified.
