2.4 Safety Instructions for Unpacking and Transport
Specific Safety Instructions
Safety Instructions for Setup
Risk of contusion due to heavy moving parts
For transportation, the Shielded RF Test Box is originally contained in a special transport protection packaging. After unpacking, there is no additional protection to prevent
opening of the drawer (door). Especially when the chamber is tilted, the door can slide
open unintentionally. This movement can cause personal injuries, especially contusion.
Risk of injury due to heavy weight
Handling the heavy Shielded RF Test Box (e.g. lifting or transporting it) can result in
personal injury. To prevent this risk, handle the Shielded RF Test Box in an ergonomic
way. For example, carry it while maintaining a straight back and optionally with the help
of a second person. The R&S TS7121A (automatic version) must be mounted by fixing
it to a stable bench/support with 4 screws, see Chapter 5, "Setting Up the System",
on page 26.
Risk of injury due to unstable mounting
The support (bench, table, rack, or the like), onto which the Shielded RF Test Box is
mounted, must be sufficiently stable to bear the chamber's weight and to withstand the
door's momentum during operation. The screws that fix the mounting brackets to the
support, must hold a tight grip in the support's material. The screws must be strong
enough to withstand a dynamic long-term load. If the support or the screws fail, the
chamber can become destabilized and eventually tip out of place. This failing could
cause personal injuries, especially contusion.
2.5 Safety Instructions for Setup
Prerequisites for the installation of the Shielded RF Test Box:
●
Provide a stable mounting space (see weight and dimensions specified in the data
sheet).
Make sure that the location, in which the Shielded RF Test Box is mounted, leaves
sufficient room for the following: You must be able to open the door, to access the
door easily from all sides and to access all connectors and mounting brackets on
the front and rear side.
●
R&S TS7121A (automatic version): Provide external control circuitry (not included
in the delivery) that complies with the circuit diagram shown in Figure 4-3 and
includes a 24 VDC power supply.
●
R&S TS7121A (automatic version): Provide compressed air by a 6 mm push-in
tube that supplies 6 bar (max. 8 bar) of filtered, grease-free compressed air.
Risk of injury due to excess pressure of the compressed air supply
If the pressure in the compressed air supply system exceeds the limit of 0.8 MPa
(8 bar), the door operates under unspecified conditions (see data sheet). The excess
pressure can cause uncontrolled situations, which can lead to personal injuries, especially contusion.

2.5.1 Positioning the Chamber
Specific Safety Instructions
Safety Instructions for Setup
To avoid this risk, only use the Shielded RF Test Box in a site that features an air preparation unit or service unit. This unit must limit the pressure of the compressed air supply to 6 bar (max. 8 bar) and provide filtered, grease-free compressed air.
Risk of injury due to heavy moving parts
Failure to fix the chamber properly before the first usage leads to a risk of injury as
described in Chapter 2.6, "Safety Instructions for Operation", on page 12. To avoid
this risk, mount the chamber securely, as described below.
Fix the Shielded RF Test Box in place by screwing the four mounting holes (Figure 4-2)
on the front and rear side of the chamber to a stable bench or support.
Risk of collision and contusion within the danger zone
The opening door can collide with a person or an obstacle that is present in a specific
area in front of the chamber. This area, which is utilized by the opened door, must be
regarded as a danger zone of the Shielded RF Test Box.
To avoid the risk of damage or personal injury, especially due to collision and contusion, everything and everybody must stay out of the danger zone.
Mark the danger zone on the ground below the chamber's opened door, as shown in
Figure 2-1.
Figure 2-1: Danger zone of the door marked on the ground, as illustrated on the right (here shown
with a similar RF test box)
If you must remove the box from this location, for example to open the top cover,
observe the Safety Instructions for Unpacking and Transport. Only operate the door
while the Shielded RF Test Box is securely mounted to a stable support.

2.6 Safety Instructions for Operation
Specific Safety Instructions
Safety Instructions for Operation
Risk of injury due to pneumatic door operation
The heavy Shielded RF Test Box features a solid metal door that can be automatically
opened and closed. Automatic operation is required for short measurement cycle times
and is realized with the R&S TS7121A (automatic) version. The heavy weight is
required to achieve high levels of electromagnetic shielding. This combination of automation and massive construction implies some inevitable risk of injury for the operators. The risk of contusion when closing the Shielded RF Test Box occurs at the movable lever mechanism (R&S TS7121M), at the movable pressure cylinder, and between
the Shielded RF Test Box door part and the Shielded RF Test Box. To avoid potential
risk of contusion, keep away from the gap between the door and the chamber, when
the door is about to be closed.
Risk of injury due to remote operation
If the chamber's door is closed by a remote operator from a distant position, a local
operator near by the chamber can be injured. Especially the operator's hands can suffer contusion while placing a DUT into the chamber or taking a DUT out of the chamber. To avoid this risk, make sure that the remote operator has a good view of the
Shielded RF Test Box and observes it while operating the door.
Risk of contusion due to heavy moving parts
If the chamber comes into an unstable position, this situation can lead to personal
injury, especially contusion. Without the pneumatic system keeping the door closed,
such a tilting movement could even contribute to a faster opening. To avoid this risk,
make sure that the chamber is securely mounted to a stable support.
Risk of injury due to high pressure
Setting up the Shielded RF Test Box can lead to a risk of personal injury due to the
pneumatic system. To avoid this risk, respect the following:
●
Before initially connecting the chamber to the compressed air supply, switch off the
compressed air supply.
●
When connecting the chamber to the compressed air supply, be aware of the possibility of a sudden opening or closing of the chamber door.
●
Observe all local and national regulations applicable for pneumatic systems.
●
Any work on the pneumatic system is a service task, which must only be carried
out by properly qualified service personnel.
Risk of injury due to excess pressure of the compressed air supply
If the pressure in the compressed air supply system exceeds the limit of 0.8 MPa
(8 bar), the door operates under unspecified conditions (see data sheet). The excess
pressure can cause uncontrolled situations, which can lead to personal injuries, especially contusion.
To avoid this risk, only use the Shielded RF Test Box in a site that features a suitable
air preparation unit or service unit. This unit must limit the pressure of the compressed
air supply to 6 bar (max. 8 bar) and provide filtered, grease-free compressed air.
