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 R&S DVS system perform the following:
1.
Shut down the system as described in section “Shutting Down
the System” on page 4-2.
2.
Disconnect all power cords from the system.
3.
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 accessed from
the outside.
For this reason, opening the casing is only necessary in exceptions.
High voltages
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 installed to
ensure proper cooling.
