3. Intentional interruption of the protective conductor either along the feed line or in
the product itself is not permitted. Doing so can result in the danger of an electric
shock from the product. If extension cables or multipoint connectors are used, they
must be checked on a regular basis to ensure that they are safe to use.
4. If the product does not have a mains switch for disconnecting the product from the
power supply
, the plug attached to the connecting cable must be used as a discon-
nect device. In such cases, it must be ensured that the power plug is within easy
reach and accessible at all times (length of connecting cable approx. 2 m). Func-
tional switches or electronic switches are not suitable for disconnecting the product
from the power supply. If products without mains switches are integrated in racks or
systems, a disconnect device must be provided at the system level.
5. Never use the product if the power cable is damaged. Check the power cable on a
regular basis to ensure that it is in proper operating condition. Take appropriate
safety measures and lay the power cable carefully to ensure that the cable will not
be damaged and that no one can be hurt by, for example, suffering an electric
shock or tripping over the cable.
6. Operation is only permitted in TN/TT supply networks which are fuse-protected with
max. 16 A (higher fuse ratings should only be used after consultation with the
Rohde & Schwarz group of companies).
7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and
completely into the socket provided. Disregard of these points can lead to sparks,
fire and/or injury.
8. Do not overload the sockets, extension cables or multipoint connectors as this can
cause fire or electric shocks.
9. For measurements in electric circuits with voltages V
rms
> 30 V, suitable measures
(e.g. appropriate measuring equipment, fusing, current limiting, electrical separa-
tion, insulation) must be taken to avoid any hazards.
10. In the case of connections to IT equipment (e.g. PCs or industrial computers), it
must be ensured that such connections satisfy the IEC60950‑1/EN60950‑1 or
IEC61010‑1/EN61010‑1 standards that apply in each case.
11. Unless expressly permitted, never remove the cover or any part of the housing
while the product is in operation. Doing so would expose electrical lines and com-
ponents and could lead to injuries, fire or damage to the product.
12. If a product is to be permanently installed, the connection between the protective
conductor terminal on site and the product's protective conductor must be made
first before any other connection is made. The product may be installed and con-
nected only by a qualified electrician.
13. For permanently installed equipment without built‑in fuses, circuit breakers or simi-
lar protective devices, the supply circuit must be fused in such a way that anyone
who has access to the product, as well as the product itself, is adequately protec-
ted from injury or damage.
