5.4 Opening and Closing the Casing
Sometimes, for particular operational reasons, it is required to open the
system’s casing and to close it after having finished the intended work.
Both tasks will be explained in this section.
5.4.1 Opening the Casing
To open the casing of the DVS system perform the following:
 Shut down the system as described in section “Shutting Down the
System” on page 4-2.
 Disconnect all power cords from the system.
 Unscrew the three screws at the rear of the system (1) and move
the cover towards the rear of the system (2).
Figure 5-4: Removal of the cover of the casing
Once the cover is slid backward, it can be taken off the system.
All items that may be replaced in case of a failure can be ac-
cessed from the outside.
For this reason, opening the casing is only necessary in excep-
tions.
The system you are working on operates with voltages
that can be hazardous to your health. Never work on the
system or access its interior with the power cable(s) being
plugged in. Make sure the power supply is disconnected
from the components you intend to work on.
The system must be operated only with the chassis’ cover in-
stalled to ensure proper cooling.
